Method Detail

getInstance

public static CharacterMapping getInstance()

Get the singleton instance of this class.

Returns:

an instance of CharacterMapping.

composeUnicodeChar

public CodePointAndVariant composeUnicodeChar(CodePointAndVariant split,
                                              boolean forbidHighplane)

Compose a new SERIF Unicode char. This function tries to compose the given char into a SERIF char which shows the same characteristics at a particular Unicode codepoint.

Parameters:

split - the char which contains a coidepoint and variant.

forbidHighplane - if the high plane is broken (e.g. on OS X).

Returns:

a CodePointAndVariant representing the same char.

extractUnicodeAttr

public CodePointAndVariant extractUnicodeAttr(CodePointAndVariant test)

Extract the given char into variant and codepoint.

Parameters:

test - the Unicode char to split up.

Returns:

A CodePointAndVariant representing the same character with explicit variant.

getAllAlternatives

public List<CodePointAndVariant> getAllAlternatives(CodePointAndVariant cpav)

Get all alternatives codePoints for this codePoint. They can be used if the original code point and variant is not available.

Parameters:

cpav - original CodePointAndVariant

Returns:

A List of alternative code points to check.

isMark

public boolean isMark(int codepoint)

Checks if the given codepoint is a "marking" codepoint. Marking codepoints do not display by themself, but are usually combined with the previous character.

Parameters:

codepoint - codepoint to check.

Returns:

true if this codepoint reprensents a mark.
