Constructor Summary

ObjectUtils()

Method Summary

static java.lang.Object	coercePrimitive(java.lang.String s, java.lang.Class c) resolve a string (specified as a primitive) to a object wrapper (i.e.
static boolean	containsObject(java.lang.Object[] src, java.lang.Object match) return true if an object is found in an array
static java.lang.Object	copyArray(java.lang.Object[] src, int newsize) create a new array of a specified size copying the contents of a specified array
static java.lang.Object	deserialize(byte[] b) deserialize an array of bytes into the original object
static java.lang.Class	getClass(java.lang.String classname) get a class based upon the specified classname (this method will correctly resolve primitives).
static java.lang.String	getMD5Signature(java.lang.Class c) get an md5 signature for a class based upon the methods (return type/name/parameters)
static java.lang.String	getParameterType(java.lang.Class c) return a class as a Java string
static boolean	isPrimitive(java.lang.String classname) return true if the specified string classname is a primitive.
static void	loadList(java.lang.Object[] src, java.util.List dest) load a list with the contents of an array
static byte[]	serialize(java.lang.Object obj) serialize an object into an array of bytes
static java.lang.String	toString(java.util.List objectList) generic function to iterate through a list of objects and return a concatenated 'toString' of them

Method Detail

coercePrimitive

public static final java.lang.Object coercePrimitive(java.lang.String s,
                                                     java.lang.Class c)

resolve a string (specified as a primitive) to a object wrapper (i.e. turn a String into a Byte based upon a specified byte.class) given its primitive class

containsObject

public static final boolean containsObject(java.lang.Object[] src,
                                           java.lang.Object match)

return true if an object is found in an array

copyArray

public static final java.lang.Object copyArray(java.lang.Object[] src,
                                               int newsize)

create a new array of a specified size copying the contents of a specified array

getClass

public static final java.lang.Class getClass(java.lang.String classname)
                                      throws java.lang.Exception

get a class based upon the specified classname (this method will correctly resolve primitives).

Throws:

java.lang.Exception

getParameterType

public static final java.lang.String getParameterType(java.lang.Class c)

return a class as a Java string

getMD5Signature

public static final java.lang.String getMD5Signature(java.lang.Class c)
                                              throws java.lang.Exception

get an md5 signature for a class based upon the methods (return type/name/parameters)

Throws:

java.lang.Exception

deserialize

public static final java.lang.Object deserialize(byte[] b)
                                          throws java.io.IOException,
                                                 java.lang.ClassNotFoundException

deserialize an array of bytes into the original object

Throws:

java.io.IOException

java.lang.ClassNotFoundException

isPrimitive

public static final boolean isPrimitive(java.lang.String classname)

return true if the specified string classname is a primitive. This returns true if classname is "byte", "short", "char", "int", etc.

loadList

public static final void loadList(java.lang.Object[] src,
                                  java.util.List dest)

load a list with the contents of an array

serialize

public static final byte[] serialize(java.lang.Object obj)
                              throws java.io.IOException

serialize an object into an array of bytes

Throws:

java.io.IOException

toString

public static final java.lang.String toString(java.util.List objectList)

generic function to iterate through a list of objects and return a concatenated 'toString' of them
