Method Detail

length

public ValueNode length()

Specified by:

length in interface ArrayLengthProvider

Returns:

the length of the array described by this node, or null if it is not available

dimension

public ValueNode dimension(int index)

The list of node which produce input for this instruction.

dimensionCount

public int dimensionCount()

The rank of the array allocated by this node, i.e. how many array dimensions.

simplify

public void simplify(SimplifierTool tool)

Description copied from class: Node

Must be overridden by subclasses that implement Simplifiable. The implementation in Node exists to obviate the need to cast a node before invoking Simplifiable.simplify(SimplifierTool).

Specified by:

simplify in interface Simplifiable

Overrides:

simplify in class AbstractNewObjectNode
