◆ operator<<() [1/3]

std::ostream & operator<<	(	std::ostream &	stream,
		const Data_Component &	component
	)

Prints a Data_Component to a stream.

Parameters

stream	The ostream where the Data_Component will be printed.
component	The Data_Component to be printed.

Returns: The stream that was written.

See also: Data_Component::print(ostream, bool)

◆ print_value()

std::ostream & print_value	(	u_int_32	value,
		int	format = `Data_Component::DECIMAL`,
		std::ostream &	stream = `std::cout`,
		int	width = `0`
	)

Prints a value in a consistent Data_Component format.

The integer value will be printed using one of these formats:

Data_Component::DECIMAL: Base 10 representation. If width is non-zero the representation will be padded with leading spaces to provide the specified field width.
Data_Component::HEX: Base 16 representation preceded by "0x". If width is non-zero the representation will be padded with leading zeros to provide width digits.
Data_Component::BOOLEAN: Either "true", if the value is non-zero, or "false" if the value is zero. If width is non-zero the representation will be padded with leading spaces to provide the specified field width.
Bits (a positive, non-zero value): As a sequence of bits, where the number of bits is specified by the format value.

@param  value   The value to be printed.
@param  format  The selected format of the output.
@param  stream  The ostream for output.
@param  width   The width of the representation, as applicable.
@return The stream that was written.

◆ bits()

std::string bits	(	const unsigned int	value,
		unsigned int	count = `0`
	)

Gets the string representation of a value in binary.

The most significant bit (msb) will be the first character in the string. If a bit is set, the corresponding character will be '1', otherwise it will be '0'. As an aid in reading the string of bits, after each fourth bit (from the right; lsb) a space character will be inserted.

Parameters

value	The value to be represented.
count	The number of bits to be included in the representation. If the count is 0 then all bits of the value will be represented.

Returns: The string representation.

Referenced by Science_Channel_Header::print(), and print_value().

◆ max_strlen()

unsigned int max_strlen ( const char ** strings )

Finds the length of the longest string in the list.

Parameters

strings The list (char**) of strings. The list must be NULL terminated.

Returns: The length of the longest string in the list. A NULL strings list has zero length.

◆ to_upper()

std::string to_upper ( const std::string & characters )

Converts all characters of a string to uppercase.

Parameters

characters The string to be uppercased.

Returns: A copy of the string with its characters converted to uppercase.

◆ PVL_parameter()

idaeim::PVL::Parameter * PVL_parameter	(	idaeim::PVL::Aggregate &	aggregate,
		std::string	pathname,
		bool	case_sensitive = `false`,
		int	skip = `0`,
		Parameter_Class_Selection	parameter_class = `ANY_PARAMETER`
	)

Gets a named PVL Parameter in an aggregate.

The Parameter to be found may be specified by a simple name, a relative pathname or an absolute pathname. A simple name is the name of a Parameter itself. A relative pathname is a simple name preceeded by the pathname of an Aggregate Parameter that must contain the Parameter with the simple name. An absolute pathname is a pathname that begins with a pathname delimiter ('/'); i.e. it is a fully qualified pathname beginning at the root of the Aggregate hierarchy, compared to a relative pathname that may begin at any Aggregate in the hierarchy.

Since it is not necessary that the pathname to each Parameter be unique, the number of matching pathnames to skip before selecting a Parameter may need to be specified to get the desired Parameter. Also, a specific type of Parameter - an Aggregate of Parameters or an Assignment of Values - may be specified. When skipping parameters, only the specified type, if any, are counted.

Parameters

aggregate	The PVL::Aggregate to search.
pathname	The pathname of the parameter to find.
case_sensitive	If true, the pathname search is case sensitive; if false the pathname is not case sensitive.
skip	The number of parameters that match the pathname to skip before selecting a matching parameter.
parameter_class	A Parameter_Class_Selection: If AGGREGATE_PARAMETER, only Aggregate parameters will be selected; if ASSIGNMENT_PARAMETER, only Assignment parameters will be selected; otherwise any type of parameter (ANY_PARAMETER) is acceptable.

Returns: A pointer to the matching parameter, or NULL if it could not be found.

◆ PVL_values()

std::vector< std::string > PVL_values	(	idaeim::PVL::Aggregate &	aggregate,
		std::string	pathname,
		bool	case_sensitive = `false`,
		int	skip = `0`
	)

Gets the values of a named PVL Parameter in an aggregate.

Only Assignment Parameters, which have Values, will be selected.

Each Value of the slected Parameter is converted to a string and added to the return vector. Numeric values may be converted back to a real number using the string_to_real function. An Array Value is flattened, at the place it occurs, to its Value contents.

Parameters

aggregate	The PVL::Aggregate to search.
pathname	The pathname of the parameter to find.
case_sensitive	If true, the pathname search is case sensitive; if false the pathname is not case sensitive.
skip	The number of parameters that match the pathname to skip before selecting a matching parameter.

Returns: A vector of zero or more string values.

		std::string	pathname,
		unsigned int	value,
		bool	case_sensitive = `false`,
		int	skip = `0`
	)

Sets the value of a named PVL parameter in an aggregate.

Only Assignment Parameters with a Value that is not an Array will be modified. However, the search for a matching pathname does not make this distinction.

Parameters

aggregate	The PVL::Aggregate to search.
pathname	The pathname of the parameter to find.
value	The int value to assign to the parameter.
case_sensitive	If true, the pathname search is case sensitive; if false the pathname is not case sensitive.
skip	The number of parameters that match the pathname to skip before selecting the parameter to modify.

Returns: true if the parameter was found; false otherwise.

◆ UTC_time()

std::string UTC_time	(	double	seconds,
		unsigned int	epoch = `Instrument::SPACECRAFT_EPOCH`
	)

Converts time in seconds to UTC representation.

The UTC representation has the form:

YYYY-MM-DDTHH:mm:SS

where all values, except the year, are zero-padded to two digits.

There are two possible implementations of this method: System functions or SPICE functions. The former will be used if INCLUDE_SPICE has not been defined at compile time and will always be used for an epoch that is not the Instrument::SPACECRAFT_EPOCH.

The system functions implementation converts the seconds argument value into the number of seconds since the host system's localtime epoch (1970) which is then converted to the UTC representation.

The SPICE functions implementation is more accurate than the system functions as it adjusts for leap seconds. This requires the use of an external file containing the leap seconds information. In addition, a file providing information about the MRO spacecraft clock must be provided. These files - called SPICE kernels - are referenced in a SPICE metakernel. The pathname to this file is identified by the SPICE_METAKERNEL_VARIABLE environment variable or, if this environment variable is not present, the DEFAULT_SPICE_METAKERNEL. The name of the SPICE_METAKERNEL_VARIABLE environment variable is set at compile time by the SPICE_METAKERNEL_VARIABLE_NAME macro; if this is not provided the default value is "SPICE_METAKERNEL". The value of the DEFAULT_SPICE_METAKERNEL is set at compile time by the DEFAULT_SPICE_METAKERNEL_PATHNAME macro; if this is not provided the default value is "/HiRISE/Data/NAIF/kernel.list". The seconds argument value is first converted to Ephemeris Time (ET). This requires a clock identifier which is specified by MRO_CLOCK_ID that is set at compile time by the MRO_CLOCK_NAIF_ID macro; if this is not provided the default value is -74999. ET is then converted to the UTC representation. N.B.: If any of the required external files are not accessible, or any of the SPICE functions fail, the INVALID_UTC_TIME value is returned. For details on the SPICE time functions see the documetation available from the ftp://naif.jpl.nasa.gov/pub/naif/toolkit_docs/C/html/individual_docs/time.html URL.

Parameters

seconds	The number of seconds since the epoch. N.B.: If the seconds value is negative the INVALID_UTC_TIME value (set at compile time by the DEFAULT_INVALID_UTC_TIME macro; if this is not provided the default value is "0000-00-00T00:00:00.000") is returned.
epoch	The epoch reference (year 1/1/XXXX at 00:00 base) for the seconds value.

Returns: A string containing the UTC representation.

Referenced by Observation::PVL_PDS().

◆ clock_count()

std::string clock_count	(	double	seconds,
		Clock_Selector	clock = `HiRISE_Clock`
	)

Converts time in seconds to clock count representation.

The clock count representation has the form:

seconds:subseconds

where seconds is a decimal count in seconds since the Instrument::SPACECRAFT_EPOCH, and subseconds is a zero-padded five digit decimal integer measuring fraction of a second ticks. For the HiRISE instrument clock each subsecond tick is Instrument::HIRISE_CLOCK_SUBTICK_MICROS microseconds; for the MRO spacecraft clock a tick is Instrument::MRO_CLOCK_SUBTICK_MICROS microseconds.

Parameters

seconds	The number of seconds since the Instrument::SPACECRAFT_EPOCH.
clock	A Clock_Selector: either the HiRISE_Clock or the MRO_Clock.

Returns: The clock count representation string.

		const std::string &	filename,
		const std::string &	extension
	)

Assembles a pathname from directory, filename, and extension segments.

The directory string, if it is not empty, is prepended to the filename string. A PATHNAME_DELIMITER character is provided between them if the directory does not already end with one. If the extension is not empty it is then appended with a '.' character delimiter.

Parameters

directory	The pathname string for the directory.

The beginning of each line of text - where a line is terminated by a new-line ('
') character - is prepended with the specified amount of whitespace (' ' characters). If no new-line is present but the lines string is not empty it is taken to be a single line that is shifted.

Parameters

lines	An arbitrary string.
amount	The amount of whitespace to shift the lines. If this is less than or equal to zero no shifting is done.

Returns: The modified lines string.

Parameters

stream	The ostream where the Gap_Map will be printed.
map	The Gap_Map to be printed.

Returns: The stream.

See also: Gap_Map::print(std::ostream&, bool) const

◆ pukool_table()

Pixel_type * pukool_table	(	const idaeim::PVL::Value &	conversion_table,
		Pixel_type *	maping_table,
		double	offset_percentage = `LUT::DEFAULT_PUKOOL_OFFSET`
	)

Generates a reverse lookup (pukool) table from a LUT PVL_PDS LOOKUP_CONVERSION_TABLE Parameter Value.

A pukool maps output pixel values back to their input CCD sensor values. The index of the pukool table corresponds to a single byte image data value. A two byte table entry value corresponds to the CCD sensor value. Thus, while a LUT maps two byte (UA::HiRISE::Pixel_type) CCD sesnor values to single byte image pixel values, a pukool maps single byte image pixel values to CCD sensor values.

However, due to the loss of precision during LUT mapping, pukool mapping is not able to identify which of of multiple CCD sensor values that mapped to the same pixel value. Since the LUT is expected to be a monotonically increasing set, a many-to-one LUT mapping is over a continuous range. The offset_percentage is used to selected a value from this range based on a percentage of the distance between the ends of the range. An offset_percentage of 0.0 will pick the low end, 1.0 will pick the high end, and 0.5 will pick the middle of the range.

Note: The last pukool entry will always map invalid (gap) pixel values to invalid (-1) CCD sensor values.

Parameters

conversion_table	The Array Value containing the reverse map ranges, as produced by the LUT::PVL_PDS method.
maping_table	The data storage arrage for the reultant pukool table. Warning: Space for 256 UA::HiRISE::Pixel_type values must be provided.
offset_percentage	A value between 0.0 and 1.0, inclusive.

Returns: The mapping_table.

Exceptions

invalid_argument If the maping_table is NULL or the offset_percentage is not in the range 0.0 to 1.0.
