Method Detail

evaluate

protected boolean evaluate(int compareResult)

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

isLeftOperation

public boolean isLeftOperation()

toString

public String toString()

returns the string representation of this operator.

Returns: string
