Method Detail

cast

public static java.lang.Object[] cast(java.lang.Class[] classes,
                                      java.lang.Object[] values)

casts a set of values to classes.

Parameters:

classes - the classes to cast to

values - the values

Returns:

the newly creates values

cast

public static java.lang.Object cast(java.lang.Class clazz,
                                    java.lang.Object object)

casts an object to a instance of clazz.

Parameters:

clazz - the class to cast to

object - the object to cast

Returns:

the casted object

forName

public static java.lang.Class forName(java.lang.String className)

returns the primitiveClass of the name given as defined by the Java VM class constants. (i.e. both "int" and "I" return int.class). Both void and "V" return void.class. null is returned whenever an unknown className is given.

Parameters:

className - the className

Returns:

Class the primitiveClass

getPrimitive

public static java.lang.Class getPrimitive(java.lang.Class wrapperClass)

gets the primitive of the given wrapperClass.

Parameters:

wrapperClass - the wrapper class

Returns:

the primitive Class. null is returned whenever wrapperClass is not a wrapperclass.

getWrapper

public static java.lang.Class getWrapper(java.lang.Class primitiveClass)

gets the wrapper of this primitive class.

Parameters:

primitiveClass - the primitive class

Returns:

the Class. null is returned whenever wrapperClass is not a wrapperclass.

toFloat

public static java.lang.Float toFloat(java.lang.Object object)

casts an object to Float.

Parameters:

object - the object to parse

Returns:

Float the result

toLong

public static java.lang.Long toLong(java.lang.Object object)

casts an object to Long.

Parameters:
