      org.progeeks.meta.DefaultMetaTable

All Implemented Interfaces:

MetaTable, StandardBean

public class DefaultMetaTable
extends 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.

                        java.util.List properties,
                        MetaClass metaClass,
                        MetaKit kit,
                        boolean autoWrap)

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

Method Detail

release

public void release()

Releases any listeners registered with the internal lists and objects. The internal list references will be cleared and the model will become invalid.

setObjects

protected void setObjects(java.util.List objects,
                          boolean autoWrap)

setProperties

protected void setProperties(java.util.List names)

addObject

public void addObject(java.lang.Object obj)

Adds the specified object to the list. If an object is a meta-object then it will be directly added to the meta-object list. Otherwise, a meta-object will be created.

getMetaObject

public MetaObject getMetaObject(int row)

Returns the specified row as a meta-object.

Specified by:

getMetaObject in interface MetaTable

getRowIndex

public int getRowIndex(MetaObject obj)

Returns the row index for the specified meta-object. This is an optional operation and may throw an UnsupportedOpreationException.

Specified by:

getRowIndex in interface MetaTable

getPropertyInfo

public PropertyInfo getPropertyInfo(int column)

Returns the property info for a given column.

Specified by:

getPropertyInfo in interface MetaTable

getColumnIndex

public int getColumnIndex(java.lang.String propertyName)

Returns the column index of the specified property.

Specified by:

getColumnIndex in interface MetaTable

Returns:

The index of the property or -1 if the name does not represent a supported property.

getRowCount

public int getRowCount()

Returns the number of rows in the table.

Specified by:

getRowCount in interface MetaTable

getColumnCount

public int getColumnCount()

Returns the number of columns in the table.

Specified by:
