public interface ArrayRangeWrite
extends FixedWithNextNodeInterface

Method Summary

Modifier and Type	Method and Description
AddressNode	getAddress()
int	getElementStride()
ValueNode	getLength() The length of the modified range.
boolean	isInitialization() Returns whether this write is the initialization of the written location.
FixedWithNextNode	postBarrierInsertionPosition() Returns the place where a post-write barrier should be inserted if one is necessary for this node.
FixedNode	preBarrierInsertionPosition() Returns the place where a pre-write barrier should be inserted if one is necessary for this node.
boolean	writesObjectArray() Return true if the written array is an object array, false if it is a primitive array.

Method Detail

getAddress

AddressNode getAddress()

getLength

ValueNode getLength()

The length of the modified range.

writesObjectArray

boolean writesObjectArray()

Return true if the written array is an object array, false if it is a primitive array.

isInitialization

boolean isInitialization()

Returns whether this write is the initialization of the written location. If it is true, the old value of the memory location is either uninitialized or zero. If it is false, the memory location is guaranteed to contain a valid value or zero.

getElementStride

int getElementStride()

preBarrierInsertionPosition

FixedNode preBarrierInsertionPosition()

Returns the place where a pre-write barrier should be inserted if one is necessary for this node. The barrier should be added before the node returned by this method.

postBarrierInsertionPosition

FixedWithNextNode postBarrierInsertionPosition()

Returns the place where a post-write barrier should be inserted if one is necessary for this node. The barrier should be added after the node returned by this method.
