Class DefaultMetaTable  

java.lang.Object
  org.progeeks.util.beans.BeanChangeSupport
      org.progeeks.meta.DefaultMetaTable

All Implemented Interfaces:

MetaTable, org.progeeks.util.beans.StandardBean

public class DefaultMetaTable

extends org.progeeks.util.beans.BeanChangeSupport

implements MetaTable

A default implementation of the MetaTable interface. This meta-table implementation contains an internal list of objects. If these objects are meta-objects then they are access directly. Otherwise, they are wrapped in meta-objects using the meta-kit provided. Optionally a list of property names can be provided or the table will pull the property names from the specified meta-class.

Version:

$Revision: 1.6 $

Nested Class Summary
private  class	DefaultMetaTable.MetaObjectListener           This is the listener that is added to all meta-objects so that any changes are forwarded along to table listeners.

 

Field Summary
private  MetaKit	kit           A reference to the meta-kit we'll use to create new meta-objects when we need to.
private  MetaClass	metaClass           The meta-class that this table is constrained by.
private  DefaultMetaTable.MetaObjectListener	objectListener           The listener that is added to all meta-objects created internally.
private  org.progeeks.util.ObservableList	objects           The original object list.
private  java.lang.String[]	properties           An array of the supported properties.
private  java.util.List	wrapperObjects           Keeps cached version of the meta-objects as they are created.

Field Detail

wrapperObjects

private java.util.List wrapperObjects

Keeps cached version of the meta-objects as they are created. If the original object list contains meta-objects, then this field will be null.

---

objects

private org.progeeks.util.ObservableList objects

The original object list. This will be the same size as the metaList, or null if the objects are all meta-objects.

---

properties

private java.lang.String[] properties

An array of the supported properties. Easy to map column to property name this way.

---

metaClass

private MetaClass metaClass

The meta-class that this table is constrained by.

---

kit

private MetaKit kit

A reference to the meta-kit we'll use to create new meta-objects when we need to.

---

objectListener

private DefaultMetaTable.MetaObjectListener objectListener

The listener that is added to all meta-objects created internally. This passes on the change events to table listeners.

Constructor Detail

DefaultMetaTable

public DefaultMetaTable(java.util.List objects,

                        MetaKit kit)

Creates a default meta-table that contains the specified list of objects.
