Detailed Description

A lookup table used to check the attributes of characters in an XML stream.

The class optimises for the ASCII character range by using a fixed size array, and then falls back to a map for non-ASCII chars.

Member Typedef Documentation

typedef std::map<uint, uint> XML::CharTable::MapCharFlags [private]

A map of character to flags.

Member Enumeration Documentation

anonymous enum [private]

The character flags.

Enumerator:

DEFAULT	The default flags.
WHITESPACE	A whitespace character.
IDENTIFIER	A character for use in identifiers.

Constructor & Destructor Documentation

XML::CharTable::CharTable ( )

Default constructor.

XML::CharTable::~CharTable ( )

Destructor.

Member Function Documentation

bool XML::CharTable::isWhitespace ( tchar cChar ) const [inline]

Check if a character is whitespace.

bool XML::CharTable::isIdentifier ( tchar cChar ) const [inline]

Check if a character is valid in an identifier.

uint XML::CharTable::getFlags ( uint nChar ) const [private]

Get the flags for the character.

uint & XML::CharTable::getFlags ( uint nChar ) [private]

Get the flags for the character.

void XML::CharTable::appendFlags	(	tchar	cChar,
		uint	nFlags
	)		`[private]`

Append flags for the character.

void XML::CharTable::appendFlags	(	tchar	cFirst,
		tchar	cLast,
		uint	nFlags
	)		`[private]`

Append flags for the character range.

The range is [First, Last] and hence is inclusive of Last unlike with iterators.

Member Data Documentation

const size_t XML::CharTable::TABLE_SIZE = 127 [static, private]

The size of the ASCII table.

uint XML::CharTable::m_anASCII[TABLE_SIZE] [private]

Lookup table for the ASCII chars.

MapCharFlags XML::CharTable::m_mapOther [private]

Lookup map for non-ASCII chars.
