Class StringLiteral

java.lang.Object

org.jruby.ir.operands.Operand

org.jruby.ir.operands.StringLiteral

public class StringLiteral
extends Operand

Represents a literal string value. This is not an immutable literal because I can gsub!, for example, and modify the contents of the string. This is not like a Java string.

Method Detail

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.

addUsedVariables

public void addUsedVariables(java.util.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

cloneForInlining

public Operand cloneForInlining(InlinerInfo ii)

Specified by:

cloneForInlining in class Operand

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

                                 java.lang.Object[] temp)

Overrides:
