Class Operator

java.lang.Object

jeb.api.ast.Operator

public class Operator
extends java.lang.Object

This class is used to represent expression operators. Operator objects are not AST elements.

Notes:

• CAST_TO_DOUBLE and CAST_TO_BOOLEAN are not legal Java operators, but present for the sake of consistency.
• LOG_IDENT is a pseudo logical operator representing the identity. It is the opposite of LOG_NOT, and can be used during AST optimizations phases to maintain expression object consistency.
• cast to non-primitive types operators can be determined using the overloaded toString() method.

Method Detail

toString

public java.lang.String toString()

Get a string representation of the operator. If the operator is a non-standard cast-to-type (where type is not a primitive type), the string representation is currently the only way to determine what the operator really does.

Overrides:
