java.lang.Object

com.oracle.graal.pointsto.flow.TypeFlow<BytecodePosition>

com.oracle.graal.pointsto.flow.OffsetStoreTypeFlow

com.oracle.graal.pointsto.flow.OffsetStoreTypeFlow.StoreIndexedTypeFlow

Enclosing class:

OffsetStoreTypeFlow

public static class OffsetStoreTypeFlow.StoreIndexedTypeFlow
extends OffsetStoreTypeFlow

Implements the type flow of an indexed store operation. The type state of an indexed store flow reflects the elements type state of the receiver array objects that triggered the store operation, i.e., the stored values. The declared type of a store operation is the component type of the receiver array, if known statically, null otherwise.
