Functions

equals()

bool QNameComparator::equals ( const Item &  op1, const Item &  op2  ) const

virtual

Determines whether op1 and op2 are equal. It is the same as calling compare() and checking whether the return value is Equal, but since comparison testing is such a common operation, this specialized function exists.

Returns

true if op1 and op2 are equal.

Parameters

op1	the first operand
op2	the second operand

Implements QPatternist::AtomicComparator.
