Class LogicalOperation

java.lang.Object

org.kigalisim.lang.operation.LogicalOperation

All Implemented Interfaces:

Operation

public class LogicalOperation
extends Object
implements Operation

Calculation that performs a logical operation on two other calculations.

Calculation that resolves two calculations and then performs a logical operation (AND, OR, XOR) on the results by using a PushDownMachine within the QubecTalk runtime.

Constructor Details

LogicalOperation

public LogicalOperation(Operation left,
 Operation right,
 String operator)

Create a new LogicalOperation.

Parameters:

left - The left operand of the logical operation.

right - The right operand of the logical operation.

operator - The logical operator (and, or, xor).

Method Details

execute

public void execute(PushDownMachine machine)

Execute the calculation and leave the result at the top of the stack.

Specified by:

execute in interface Operation

Parameters:

machine - The machine in which to execute the calculation if needed.

getStaticSemantics

public OperationStaticSemantics getStaticSemantics()

Get a record describing this operation's semantics.

Get a record describing this operation's semantics that are inferrable from its static expression in code. In other words, properties and effects which do not require inspection at time of executing the operation.

Specified by:

getStaticSemantics in interface Operation

Returns:

Inference of common static properties found for this operation.
