Method Detail
-
evaluate
protected boolean evaluate(int compareResult)
- Specified by:
evaluate
in classAbstractCompareOperator
-
getLevel
public int getLevel()
-
isLeftOperation
public boolean isLeftOperation()
Description copied from interface:InfixOperator
Defines the bind-direction of the operator. That direction defines, in which direction a sequence of equal operators is resolved.- Returns:
- true, if the operation is left-binding, false if right-binding
-
isAssociative
public boolean isAssociative()
Defines, whether the operation is associative. For associative operations, the evaluation order does not matter, if the operation appears more than once in an expression, and therefore we can optimize them a lot better than non-associative operations (ie. merge constant parts and precompute them once).- Returns:
- true, if the operation is associative, false otherwise
