Method Detail

Get_Stream

public static InputStream Get_Stream(String source)

Obtain an InputStream from a named source.

The source String is first treated as a URL specification. If this fails the source is treated as a pathname to a locally accessible file. If no file is found the source is treated as the name of a system resource, which can find a file inside a jar file when the application is being run from a jar.

Parameters:

source - The name of a stream source.

Returns:

An InputStream, or null if no source file can be found.

Get_Image_Stream

public static ImageInputStream Get_Image_Stream(String source)

Obtain an ImageInputStream from a named source.

If a URL can be constructed from the source String an attempt is made to construct an HTTP_ImageInputStream from the URL. If the source is not a valid URL, the source is treated as a pathname to a locally accessible file and an attempt is made to construct a FileImageInputStream from the File.

Parameters:

source - The name of a stream source.

Returns:

An ImageInputStream, or null if no source is accessible.
