Constructor Summary

StringSubstitution()
Default constructor initializing substitution to a zero length String.

StringSubstitution(java.lang.String substitution)
Creates a StringSubstitution representing the given string.

Method Summary

void	appendSubstitution(java.lang.StringBuffer appendBuffer, MatchResult match, int substitutionCount, PatternMatcherInput originalInput, PatternMatcher matcher, Pattern pattern) Appends the substitution to a buffer containing the original input with substitutions applied for the pattern matches found so far.
java.lang.String	getSubstitution() Returns the string substitution represented by this object.
void	setSubstitution(java.lang.String substitution) Sets the substitution represented by this StringSubstitution.
java.lang.String	toString() Returns the same value as getSubstitution().

Constructor Detail

StringSubstitution

public StringSubstitution()

Default constructor initializing substitution to a zero length String.

StringSubstitution

public StringSubstitution(java.lang.String substitution)

Creates a StringSubstitution representing the given string.

Parameters:

substitution - The string to use as a substitution.

Method Detail

setSubstitution

public void setSubstitution(java.lang.String substitution)

Sets the substitution represented by this StringSubstitution. You should use this method in order to avoid repeatedly allocating new StringSubstitutions. It is recommended that you allocate a single StringSubstitution and reuse it by using this method when appropriate.

Parameters:

substitution - The string to use as a substitution.

getSubstitution

public java.lang.String getSubstitution()

Returns the string substitution represented by this object.

Returns:

The string substitution represented by this object.

toString

public java.lang.String toString()

Returns the same value as getSubstitution().

Overrides:

toString in class java.lang.Object

Returns:

The string substitution represented by this object.

appendSubstitution

public void appendSubstitution(java.lang.StringBuffer appendBuffer,
                               MatchResult match,
                               int substitutionCount,
                               PatternMatcherInput originalInput,
                               PatternMatcher matcher,
                               Pattern pattern)

Appends the substitution to a buffer containing the original input with substitutions applied for the pattern matches found so far. See Substitution.appendSubstition() for more details regarding the expected behavior of this method.

Specified by:

appendSubstitution in interface Substitution

Parameters:

appendBuffer - The buffer containing the new string resulting from performing substitutions on the original input.

match - The current match causing a substitution to be made.

substitutionCount - The number of substitutions that have been performed so far by Util.substitute.

originalInput - The original input upon which the substitutions are being performed. This is a read-only parameter and is not modified.

matcher - The PatternMatcher used to find the current match.

pattern - The Pattern used to find the current match.
