◆ Includes()

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

Determines if block is a subset of the unicode_block object.

Parameters
blockThe Unicode block to check.
Returns
Whether or not block is a subset of the unicode_block object.
Return values
trueblock is a subset of the current unicode_block.
falseblock is NOT a subset of the current unicode_block.

BeOS R4

◆ operator!=()

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

Determines if the block object are not equal.

Parameters
blockThe unicode block to compare against.
Returns
true if the block object are NOT equal, false if the block objects are exactly equal.
Since
BeOS R4

◆ operator=()

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

Copies block data into the left-hand side object.

Parameters
blockThe unicode block to copy from.
Returns
A copy of block.

BeOS R4

◆ operator==()

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

Determines if the block object are exactly equal.

Parameters
blockThe unicode block to compare against.
Returns
true if the block object are exactly equal, false otherwise.
Since
BeOS R4

◆ 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
blockThe Unicode block to form a union with.
Returns
The union of block and the unicode_block object.
