Method Detail

cast

public static Object[] cast(Class<?>[] classes,
                            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 Object cast(Class<?> clazz,
                          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 Class<?> forName(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 Class<?> getPrimitive(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 Class<?> getWrapper(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.

toBoolean

public static Boolean toBoolean(Object object)

casts an object to Boolean.

Parameters:

object - the object

Returns:

Boolean

toByte

casts an object to Byte.

Parameters:

object - the object

Returns:

Byte

toCharacter

public static Character toCharacter(Object object)

casts an object to Character.

Parameters:

object - the object to parse

Returns:

Integer the result

toDouble

public static Double toDouble(Object object)

casts an object to Double.

Parameters:

object - the object to parse

Returns:

Integer the result

toFloat

public static Float toFloat(Object object)

casts an object to Float.

Parameters:

object - the object to parse

Returns:

Float the result

toLong

public static Long toLong(Object object)

casts an object to Long.

Parameters:

object - the object to parse

Returns:

Long the result

toShort

public static Short toShort(Object object)

casts an object to Short.

Parameters:

object - the object to parse

Returns:

Long the result

toInteger

public static Integer toInteger(Object object)

casts an object to Integer.

Parameters:

object - the object to parse

Returns:

Integer the result
