Detailed Description

A bidirectional map from character code units to unspecified code points

Remarks

The actual code point nature is unspecified, but it can either be unicode code points or CID(s) as used in CID keyed fonts. For generic terminology see https://en.wikipedia.org/wiki/Character_encoding#Terminology See also 5014.CIDFont_Spec, 2.1 Terminology

Member Function Documentation

PushMapping() [1/2]

void PdfCharCodeMap::PushMapping	(	const PdfCharCode &	codeUnit,
		codepoint	codePoint )

Convenience method to push a single code point mapping

PushMapping() [2/2]

void PdfCharCodeMap::PushMapping	(	const PdfCharCode &	codeUnit,
		const codepointview &	codePoints )

Method to push a mapping. Given string can be a ligature, es "ffi"

TryGetCharCode() [1/2]

bool PdfCharCodeMap::TryGetCharCode	(	codepoint	codePoint,
		PdfCharCode &	code ) const

Try get char code from unicode code point

TryGetCharCode() [2/2]

bool PdfCharCodeMap::TryGetCharCode	(	const codepointview &	codePoints,
		PdfCharCode &	code ) const

Try get char code from unicode code points

Parameters

codePoints

sequence of unicode code points. All the sequence must match

TryGetCodePoints()

bool PdfCharCodeMap::TryGetCodePoints	(	const PdfCharCode &	codeUnit,
		std::vector< codepoint > &	codePoints ) const

Returns false when no mapped identifiers are not found in the map

TryGetNextCharCode()

bool PdfCharCodeMap::TryGetNextCharCode	(	std::string_view::iterator &	it,
		const std::string_view::iterator &	end,
		PdfCharCode &	code ) const

Try get char code from utf8 encoded range

Remarks

It assumes it != and it will consumes the interator also when returning false
