Overrides:

hasKnownValue in class ImmutableLiteral<RubyString>

Returns:

true if a known compile-time value.

hashCode

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object other)

Overrides:

equals in class java.lang.Object

toString

Overrides:

toString in class java.lang.Object

cloneForInlining

Overrides:

cloneForInlining in class ImmutableLiteral<RubyString>

createCacheObject
