Class ArrayNullCheckTag

java.lang.Object

soot.jimple.toolkits.annotation.tags.ArrayNullCheckTag

All Implemented Interfaces:

OneByteCodeTag, Tag

public class ArrayNullCheckTag
extends Object
implements OneByteCodeTag

ArrayNullCheckTag combines ArrayCheckTag and NullCheckTag into one tag. It uses bits of one byte value to represent the check information. The right-most two bits stand for the array bounds checks, and the right third bit represents the null check.

For array references, the right three bits are meaningful; for other object refrences, only null check bit should be used.
