Method Detail

coerceBoxed

java.lang.Number coerceBoxed(java.lang.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

java.lang.Class getReturnType()
