Method Detail

isAnExecutableMethod

public static boolean isAnExecutableMethod(java.lang.reflect.Method m)

Test if the given method requires parameters of a native type. In this case the method can be executed.

Parameters:

m - The method to be tested.

Returns:

True if the method requires only native-type parameters. A parameter is native type if int, long, ... or its corresponding wrapper class (Integer, Double, Long, ...).

isCollection

public static boolean isCollection(java.lang.Class f)

Test if the given class implements the java.util.Collection interface. The whole hierarchy of the class is tested.

Parameters:

f - The class to be tested.

Returns:

True if the class is a Collection, false otherwise.

isEditable

public static boolean isEditable(java.lang.Class c)

Test if the given class is a wrapper for a native type or a string. It could be a Double, Long, Integer, Float, String, Character or Boolean.

Parameters:

c - The class to be tested.

Returns:

True if class is of a native type, false in any other case.

isEditable

public static boolean isEditable(java.lang.Object o)

Test if the given object is a wrapper for a native type or a string. It could be a Byte, Double, Long, Short, Integer, Float, String, Character or Boolean.

Parameters:

o - The object to be tested.

Returns:

True if class is of a native type, false in any other case.

setValueToObject

public static void setValueToObject(java.lang.Object o,
                                    java.lang.Object val)

Set a given value wrapped by an Object into the wrapper object.

Parameters:

o - The object to be updated. It must be of a native wrapper class (String, Double, Long, ...).

val - An object whose toString() method return a valid format for the class type of object o.
