Method Detail

getWrapperClass

protected static java.lang.Class getWrapperClass(java.lang.Class c)

Get wrapper class for a given class. If the class is for a primitive number type, then the wrapper class will be returned. If it is no primitive number type, we return the class itself.

argumentClassIsParameterClass

protected static boolean argumentClassIsParameterClass(java.lang.Class argumentClass,
                                                       java.lang.Class parameterClass)

Realizes an unsharp equal for the class. In general we return true if the provided arguments are the same. But we will also return true if our argument class is a wrapper for the parameter class. For example the parameter is an int and the argument class is a wrapper.

replaceWithMoreSpecificType

protected static java.lang.invoke.MethodType replaceWithMoreSpecificType(java.lang.Object[] args,
                                                                         java.lang.invoke.MethodType callSiteType)

Replaces the types in the callSiteType parameter if more specific types given through the arguments. This is in general the case, unless the argument is null.

isIntCategory

protected static boolean isIntCategory(java.lang.Class x)

isLongCategory

protected static boolean isLongCategory(java.lang.Class x)

isBigDecCategory

protected static boolean isBigDecCategory(java.lang.Class x)

isDoubleCategory

protected static boolean isDoubleCategory(java.lang.Class x)
