Method Details

toString

public String toString()

Description copied from class: Expression

Subclasses should return a String representing the parsed expression.

Overrides:

toString in class BinaryExpression

evaluate

public Object evaluate()

Performs a logical AND operation. Note this operation is naturally short- circuited by using && in conjunction with postponing RHS evaluation.

Specified by:

evaluate in interface IExpression

Overrides:

evaluate in class Expression
