Fields Summary
public final int
size
The size of this value.
public final Set
insns
The instructions that can produce this value. For example, for the Java code below, the instructions that can produce the value of i at line 5 are the txo ISTORE instructions at line 1 and 3: 
1: i = 0;
2: if (...) {
3: i = 1;
4: }
5: return i;
This field is a set of {@link AbstractInsnNode} objects.
Constructors Summary
public DataflowValue(int size)

    this(size, Collections.EMPTY_SET);
public DataflowValue(int size, oracle.toplink.libraries.asm.tree.AbstractInsnNode insn)

    this.size = size;
    this.insns = new HashSet();
    this.insns.add(insn);
public DataflowValue(int size, Set insns)

    this.size = size;
    this.insns = insns;
Methods Summary
public booleanequals(Value value)

    DataflowValue v = (DataflowValue)value;
    return size == v.size && insns.equals(v.insns);
public intgetSize()

    return size;
