Method Summary

Modifier and Type	Method	Description
static Class<?>[]	argumentTypes(Object... arguments)	Convert method/constructor call arguments to their corresponding types. null values are represented using the Parameters.NULL_ARGUMENT_TYPE type
static boolean	parameterTypesMatches(Class<?>[] actualParameterTypes, Class<?>[] declaredParameterTypes, boolean exactMatch)	Check if an array of actual-parameter-types MATCH an array of declared-parameter-types while taking null actual parameter types and BoxedTypes.boxedType(java.lang.Class<?>) into consideration (in case exactMatch is false)

parameterTypesMatches

public static boolean parameterTypesMatches(Class<?>[] actualParameterTypes,
 Class<?>[] declaredParameterTypes,
 boolean exactMatch)

Check if an array of actual-parameter-types MATCH an array of declared-parameter-types while taking null actual parameter types and BoxedTypes.boxedType(java.lang.Class<?>) into consideration (in case exactMatch is false)

Parameters:

actualParameterTypes - the actual parameter types (deduced from actual parameter values)

declaredParameterTypes - the declared parameter types defined on the Method or Constructor

exactMatch - Must the match be exact (each parameter type MUST match precisely)
or do we allow testing using BoxedTypes.boxedType(Class), null actualParameterTypes and isAssignableFrom checks to bypass individual type matches

Returns:

true if the parameter types match or not

argumentTypes

public static Class<?>[] argumentTypes(Object... arguments)

Convert method/constructor call arguments to their corresponding types.
null values are represented using the Parameters.NULL_ARGUMENT_TYPE type

Parameters:

arguments - arguments

Returns:

the argument types
