◆ is_equal_hard()

virtual DLLEXPORT bool DateTimeNode::is_equal_hard ( const AbstractQoreNode v,
ExceptionSink xsink 
) const
virtual

tests for equality ("deep compare" including all contained values for container types) without type conversions (hard compare)

Parameters
vthe value to compare
xsinkif an error occurs, the Qore-language exception information will be added here
Returns
true if the objects are equal, false if not

Implements AbstractQoreNode.

◆ is_equal_soft()

virtual DLLEXPORT bool DateTimeNode::is_equal_soft ( const AbstractQoreNode v,
ExceptionSink xsink 
) const
virtual

tests for equality with possible type conversion (soft compare)

this function does not throw any Qore-language exceptions

Parameters
vthe value to compare
xsinkis not used in this implementation of the function

Implements AbstractQoreNode.
