Public Methods

Method Description
Clone ( CloneContext clonectx ) : Mono.CSharp.Expression
ContainsEmitWithAwait ( ) : bool
ConvertExplicitly ( bool in_checked_context, System.TypeSpec target_type ) : Constant

Maybe ConvertTo name is better. It tries to convert `this' constant to target_type. It throws OverflowException
ConvertImplicitly ( System.TypeSpec type ) : Constant
CreateConstantFromValue ( System.TypeSpec t, object v, Mono.CSharp.Location loc ) : Constant
CreateExpressionTree ( ResolveContext ec ) : Mono.CSharp.Expression
EmitSideEffect ( EmitContext ec ) : void
Error_ValueCannotBeConverted ( ResolveContext ec, System.TypeSpec target, bool expl ) : void
ExtractConstantFromValue ( System.TypeSpec t, object v, Mono.CSharp.Location loc ) : Constant
GetTypedValue ( ) : object
GetValue ( ) : object

This is used to obtain the actual value of the literal cast into an object.
GetValueAsLiteral ( ) : string
GetValueAsLong ( ) : long
ImplicitConversionRequired ( ResolveContext ec, System.TypeSpec type ) : Constant
IsDefaultInitializer ( System.TypeSpec type ) : bool

Need to pass type as the constant can require a boxing and in such case no optimization is possible
MakeExpression ( BuilderContext ctx ) : System.Linq.Expressions.Expression
Reduce ( ResolveContext ec, System.TypeSpec target_type ) : Constant
Resolve ( ResolveContext rc ) : bool
ToString ( ) : string
TryReduce ( ResolveContext rc, System.TypeSpec targetType ) : Constant
