Method Detail

coerceBoxed

Number coerceBoxed(Number numToCoerce)

Coerce the given number to a previously determined type, assuming the type is a Boxed type. Allows coerce to lower resultion number. Does't coerce to primitive types.

Parameters:

numToCoerce - is the number to coerce to the given type

Returns:

the numToCoerce as a value in the given result type

getReturnType

Class getReturnType()

coerceCodegen

CodegenExpression coerceCodegen(CodegenExpression value,
                                Class valueType)

coerceCodegenMayNullBoxed

CodegenExpression coerceCodegenMayNullBoxed(CodegenExpression value,
                                            Class valueType,
                                            CodegenContext context)
