CharClass
protected CharClass(int containsBmp,
int containsNonBmp)
Create a character class
containsBmp
- NONE, SOME, or ALL, depending on whether the character class contains all
the BMP characters, some of the BMP characters, or none of the BMP characterscontainsNonBmp
- NONE, SOME, or ALL, depending on whether the character class contains all
the non-BMP characters, some of the non-BMP characters, or none of the non-BMP characters
addNonBmpRanges
public void addNonBmpRanges(List ranges)
Add to a supplied List, ranges of non-BMP characters that are matched by this character class.
Default implementation does nothing.
ranges
- a List to which this method will add zero or more Range objects denoting ranges
of non-BMP characters
getContainsBmp
public int getContainsBmp()
Determine whether this character class contains NONE, SOME, or ALL of the BMP characters
getContainsNonBmp
public int getContainsNonBmp()
Determine whether this character class contains NONE, SOME, or ALL of the non-BMP characters
getSingleChar
public int getSingleChar()
If this character class contains a single character, get that character
- the single character matched by this character class, or -1 if it matches multiple characters
output
public final void output(FastStringBuffer buf)
Output a representation of this character class to the supplied buffer
buf
- the supplied buffer
outputBmp
public abstract void outputBmp(FastStringBuffer buf)
Output a representation of the subset of this character class that's within the BMP, to
a supplied buffer
buf
- the supplied buffer
outputComplementBmp
public abstract void outputComplementBmp(FastStringBuffer buf)
Output a representation of the complement of the subset of this character class that's within the BMP, to
a supplied buffer
buf
- the supplied buffer
