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 Summary

Modifier and TypeMethod and Description
public void
addUsedVariables(List<Variable> l)

Implements abstract org.jruby.ir.operands.Operand.addUsedVariables.

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.

public Operand
cloneForInlining(CloneInfo ii)

Implements abstract org.jruby.ir.operands.Operand.cloneForInlining.

public static Filename
decode(IRReaderDecoder d)

public void
encode(IRWriterEncoder e)

Overrides org.jruby.ir.operands.Operand.encode.

public OperandType
getOperandType()

Implements abstract org.jruby.ir.operands.Operand.getOperandType.

public boolean
hasKnownValue()

Overrides org.jruby.ir.operands.Operand.hasKnownValue.

Do we know the value of this operand at compile-time?

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

Overrides org.jruby.ir.operands.Operand.retrieve.

public void
visit(IRVisitor visitor)

Overrides org.jruby.ir.operands.Operand.visit.

public boolean hasKnownValue()

Overrides org.jruby.ir.operands.Operand.hasKnownValue.

Doc from org.jruby.ir.operands.Operand.hasKnownValue.

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).

Returns:boolean

true if a known compile-time value.
