Includes()

bool unicode_block::Includes ( const unicode_block &  block ) const

inline

Determines if block is a subset of the unicode_block object.

Parameters

block

The Unicode block to check.

Returns

Whether or not block is a subset of the unicode_block object.

Return values

true	block is a subset of the current unicode_block.
false	block is NOT a subset of the current unicode_block.

operator!=()

bool unicode_block::operator!= ( const unicode_block &  block ) const

inline

Determines if the block object are not equal.

Parameters

block

The unicode block to compare against.

Returns

true if the block object are NOT equal, false if the block objects are exactly equal.

operator=()

unicode_block & unicode_block::operator= ( const unicode_block &  block )

inline

Copies block data into the left-hand side object.

Parameters

block

The unicode block to copy from.

Returns

A copy of block.

operator==()

bool unicode_block::operator== ( const unicode_block &  block ) const

inline

Determines if the block object are exactly equal.

Parameters

block

The unicode block to compare against.

Returns

true if the block object are exactly equal, false otherwise.

operator|()

unicode_block unicode_block::operator| ( const unicode_block &  block ) const

inline

Creates and returns a new unicode_block object that is the union of block and the unicode_block object.

Parameters

block

The Unicode block to form a union with.

Returns

The union of block and the unicode_block object.
