Method Detail

toString

public String toString()

Overrides:

toString in class Object

hasKnownValue

public boolean hasKnownValue()

Description copied from class: Operand

Do we know the value of this operand at compile-time? If we do then it may be possible to constant propagate (one case: We also know it is also an ImmutableLiteral).

Overrides:

hasKnownValue in class Operand

Returns:

true if a known compile-time value.

getArray

public Operand getArray()

getSimplifiedOperand

public Operand getSimplifiedOperand(Map<Operand,Operand> valueMap,
                           boolean force)

Overrides:

getSimplifiedOperand in class Operand

addUsedVariables

public void addUsedVariables(List<Variable> l)

Append the list of variables used in this operand to the input list

Specified by:

addUsedVariables in class Operand

cloneForDepth

public Operand cloneForDepth(int n)

When fixing up splats in nested closure we need to tweak the operand if it is a LocalVariable

Specified by:

cloneForDepth in interface DepthCloneable

cloneForInlining

public Operand cloneForInlining(CloneInfo ii)

Specified by:

cloneForInlining in class Operand

retrieve

public Object retrieve(ThreadContext context,
              IRubyObject self,
              StaticScope currScope,
              DynamicScope currDynScope,
              Object[] temp)

Overrides:

retrieve in class Operand

encode

public void encode(IRWriterEncoder e)

Overrides:

encode in class Operand

decode

public static Splat decode(IRReaderDecoder d)

visit

public void visit(IRVisitor visitor)

Overrides:

visit in class Operand
