Constructor Summary

BeanUtil()

Method Summary

static boolean	equal(java.lang.Object obj1, java.lang.Object obj2) Simply compares two objects using equals() method and takes care about nulls null == null = false
static java.lang.Object	getPrivilegedProperty(java.lang.Object instance, java.lang.String propertyName) Retrieves a privilged property
static java.beans.PropertyDescriptor	getPropertyDescriptor(java.lang.Object anInstance, java.lang.String aPropertyName) Returns property descriptor of the selected property for the selected object instance.
static java.beans.PropertyDescriptor[]	getPropertyDescriptors(java.lang.Class instanceClass) Returns property descriptor list for a given object class selected object instance.
static java.lang.Class	loadClass(java.lang.String className)
static java.lang.Class	loadClass(java.lang.String className, java.lang.ClassLoader classLoader)
static byte[]	save(java.lang.Object object) Serialize an object to an array of bytes.
static void	setProperties(java.lang.Object anInstance, java.util.Map propertyValues)
static void	setProperty(java.lang.Object anInstance, java.lang.String aPropertyName, java.lang.Object aValue) Set's a particular property of the instance Usage: SomeBean bean = new SomeBean(); Integer propertyValue = new Integer(10); ClassTools.setProperty(bean, "propertyName", propertyValue); is in fact equal to bean.setPropertyValue(propertyValue); Simple types are also supported int propertyValue = 10; ClassTools.setProperty(bean, "intPropertyName", new Integer(propertyValue));
static boolean	setPropertyByString(java.lang.Object anInstance, java.lang.String aPropertyName, java.lang.String aStringValue) Set's a particular property of the instance by string value Usage: SomeBean bean = new SomeBean(); ObjectUtil.setPropertyByString(bean, "someProperty", "10");
static boolean	setSpecialProperty(java.lang.Object instance, java.lang.String propName, java.lang.Object value) Sets a "special" property, i.e.
static java.lang.Object	StringToValue(java.lang.String s, java.lang.Class t) Converts String value to the type specified by class

Method Detail

StringToValue

public static java.lang.Object StringToValue(java.lang.String s,
                                             java.lang.Class t)

Converts String value to the type specified by class

getPropertyDescriptor

public static java.beans.PropertyDescriptor getPropertyDescriptor(java.lang.Object anInstance,
                                                                  java.lang.String aPropertyName)

Returns property descriptor of the selected property for the selected object instance.

Parameters:

anInstance -

getPropertyDescriptors

public static java.beans.PropertyDescriptor[] getPropertyDescriptors(java.lang.Class instanceClass)

Returns property descriptor list for a given object class selected object instance.

Parameters:

instanceClass -

Returns:

PropertyDescriptor[] for passed in class

setProperty

public static void setProperty(java.lang.Object anInstance,
                               java.lang.String aPropertyName,
                               java.lang.Object aValue)

Set's a particular property of the instance Usage: SomeBean bean = new SomeBean(); Integer propertyValue = new Integer(10); ClassTools.setProperty(bean, "propertyName", propertyValue); is in fact equal to bean.setPropertyValue(propertyValue); Simple types are also supported int propertyValue = 10; ClassTools.setProperty(bean, "intPropertyName", new Integer(propertyValue));

setPropertyByString

public static boolean setPropertyByString(java.lang.Object anInstance,
                                          java.lang.String aPropertyName,
                                          java.lang.String aStringValue)

Set's a particular property of the instance by string value Usage: SomeBean bean = new SomeBean(); ObjectUtil.setPropertyByString(bean, "someProperty", "10");

setSpecialProperty

public static boolean setSpecialProperty(java.lang.Object instance,
                                         java.lang.String propName,
                                         java.lang.Object value)

Sets a "special" property, i.e. a property with special notation to indicate setting into an map or list. For example:

  setSpecialProperty (instance, "value(name)", "charles") -> calls instance.setValue ("name", "charles")
  setSpecialProperty (instance, "value[1]", "charles") -> calls instance.setValue ("charles", 1)
 

Parameters:

instance -

propName -

value -

Returns:
