Method Summary

Modifier and Type	Method and Description
boolean	hasOperand(Node node)
Value	operand(Node node) Returns the operand that has been previously initialized by setResult(ValueNode, Value) with the result of an instruction.
Value	setResult(ValueNode node, Value operand) Associates operand with the node in the current block.
ValueNode	valueForOperand(Value value) Gets the the ValueNode that produced a value.

Method Detail

operand

Value operand(Node node)

Returns the operand that has been previously initialized by setResult(ValueNode, Value) with the result of an instruction. It's a code generation error to ask for the operand of ValueNode that doesn't have one yet.

Parameters:

node - A node that produces a result value.

hasOperand

boolean hasOperand(Node node)

Returns:

true if there is an operand associated with the node in the current block.

setResult

Value setResult(ValueNode node,
                Value operand)

Associates operand with the node in the current block.

Returns:

operand

valueForOperand

ValueNode valueForOperand(Value value)

Gets the the ValueNode that produced a value. If the value is not associated with a ValueNode null is returned. This method is intended for debugging purposes only.
