org.jruby.ir.operands.Filename

public class Filename
extends Operand

Represents the script's __FILE__. Isolated as its own operand because we need to be able to replace it when loading persisted IR from a location different than original script.

Method Detail

getOperandType

public OperandType getOperandType()

Specified by:

getOperandType in class Operand

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.

encode

public void encode(IRWriterEncoder e)

Overrides:

encode in class Operand

decode

public static Filename decode(IRReaderDecoder d)

visit

public void visit(IRVisitor visitor)

Overrides:

visit in class Operand

retrieve

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

Overrides:

retrieve in class Operand

cloneForInlining

public Operand cloneForInlining(CloneInfo ii)

Specified by:

cloneForInlining in class Operand

addUsedVariables

public void addUsedVariables(List<Variable> l)

Description copied from class: Operand

Append the list of variables used in this operand to the input list -- force every operand to implement this because a missing implementation can cause bad failures.

Specified by:

addUsedVariables in class Operand
