                              Stamp stamp)

Method Detail

getArray

public abstract ValueNode getArray()

The array that is written to.

getIndex

public abstract ValueNode getIndex()

The first modified index.

getLength

public abstract ValueNode getLength()

The length of the modified range.

isObjectArray

public abstract boolean isObjectArray()

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

isInitialization

public abstract 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.
