java.lang.Exception

Type Parameters:

R - type of return

Parameters:

vis - visitor

Returns:

result of type R

equals

public boolean equals(java.lang.Object obj)

Overrides:

copy

public MilliSecondDatePropExpression copy()

Description copied from interface: PropExpression

Generate an equivalent (and where possible immutable) copy of this expression. Most implementing types should themselves be immutable, calling copy on their arguments and returning a self-reference for copy. In this case the return type of the function should be narrowed to the implemeting sub-type.

Specified by:

copy in interface PropExpression<java.lang.Long>

Returns:

PropExpression
