protected SurrogateRegexTranslator.CharClass(int containsBmp,
                                             int containsNonBmp)

Create a character class

Parameters:

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 characters

containsNonBmp - 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

public int getContainsBmp()

Determine whether this character class contains NONE, SOME, or ALL of the BMP characters

Returns:

NONE, SOME, or ALL

getContainsNonBmp

public int getContainsNonBmp()

Determine whether this character class contains NONE, SOME, or ALL of the non-BMP characters

Returns:

NONE, SOME, or ALL

output

public final void output(FastStringBuffer buf)

Output a representation of this character class to the supplied buffer

Parameters:

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

Parameters:

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

Parameters:

buf - the supplied buffer

getSingleChar

public int getSingleChar()

If this character class contains a single character, get that character

Returns:

the single character matched by this character class, or -1 if it matches multiple characters

addNonBmpRanges

public void addNonBmpRanges(java.util.List ranges)
