IlpAbstractAdapter (Rogue Wave JViews 9.2 API)

java.lang.Object
- ilog.cpl.datasource.IlpAbstractAdapter

All Implemented Interfaces:

DataSourceListener, IlpRepresentationObjectMapper, EventListener

Direct Known Subclasses:

IlpAbstractHierarchyAdapter, IlpListAdapter
```
public abstract class IlpAbstractAdapter
extends Object
implements DataSourceListener, IlpRepresentationObjectMapper
```
Abstract adapter.
Provides support for the association with a data source, filtering, and JavaBean property change events.
This abstract adapter assumes that representation objects are created only when there is a data source AND a model. If one of those is removed, all representation objects are cleared.

Since:

JTGO 3.0

    id - Object identifier
    
    Since:
    
    JTGO 3.0
  - isRepresenting
```
public boolean isRepresenting()
```
    Returns true if the adapter is active, that is, representing objects from a data source in a model.
    This is a bound property.
  - hasModel
```
public abstract boolean hasModel()
```
    Returns true if the adapter is connected to a model.
  - setDataSource
```
public void setDataSource(IlpDataSource dataSource)
```
    Sets the data source.
    The representation objects are created if the adapter also has model. Note that the adapter also waits for a model to listen to data source events.
    This is a bound property.
    
    Parameters:
    
    dataSource - The data source used by adapter.
  - getDataSource
```
public IlpDataSource getDataSource()
```
    Returns the data source.
    This is a bound property.
    
    Returns:
    
    The data source used by the adapter.
  - setFilter
```
public void setFilter(IlpFilter newfilter)
```
    Sets the filter.
    The new filter is only applied if it is different from the existing filter. To perform this validation, the method equals is used in the filter instances.
    The data source objects are filtered, so only IlpObjects that pass through the filter are added to the model.
    This is a bound property.
    Note: This property can be customized using CSS, as illustrated below:
```
 Adapter {
   filter: @+filterDef;
 }
 Subobject#filterDef {
   ...
 }
 
```
    Parameters:
    
    newfilter - The filter to use to filter business objects. This parameter may be null, meaning the business objects are not filtered.
  - getFilter
```
public IlpFilter getFilter()
```
    Returns the filter.
    This is a bound property.
    
    Returns:
    
    The filter used to filter business objects.
    
    See Also:
    
    setFilter(IlpFilter)
  - setExcludedClasses
```
public void setExcludedClasses(List<IlpClass> newExclusion)
```
    Sets the list of business classes that should be excluded by this adapter.
    By default, the list is empty. This means that all business objects will be converted to representation objects. However, this does not include the ones that do not match the current filter criteria.
    If you specify business classes in the list, business objects from the given classes or from one of its subclasses will be automatically filtered. Their representation will not be created in the associated representation model.
    The current implementation is not very efficient, as it removes all representation objects and recreates them.
    Note:This property can be customized using CSS, as illustrated below:
```
 Adapter {
   excludedClasses: "business class A, business class B";
 }
 
```
    To represent all classes:
```
 Adapter {
   excludedClasses: '';
 }
 
```
    Parameters:
    
    newExclusion - The list of IlpClass. Note that this list is copied to the internal list of excluded classes.
    
    Since:
    
    JTGO 4.0
  - getExcludedClasses
```
public List<IlpClass> getExcludedClasses()
```
    Returns the list of excluded classes.
    It may well be an empty list.
    
    Returns:
    
    A copy of the internal list of excluded classes.
    
    Since:
    
    JTGO 4.0
  - initializeExcludedClasses
```
protected void initializeExcludedClasses()
```
    Initializes the predefined list of excluded classes. In general, this list is empty. This method is overridden in subclasses if the specific adapter does not handle some predefined classes.
  - replaceExcludedClasses
```
protected void replaceExcludedClasses(List<IlpClass> newExclusion)
```
    This method is called to replace the existing excluded class list with a new one.
    
    Parameters:
    
    newExclusion - New exclusion list.

```
public void batchStarted(DataSourceEvent e)
```
    Called when a batch of modifications of the data source has started.
    
    Specified by:
    
    batchStarted in interface DataSourceListener
    
    Since:
    
    JTGO 4.0
    
    Internal: do not use!
  - batchEnded
```
public void batchEnded(DataSourceEvent e)
```
    Called when a batch of modifications of the data source has ended.

    Internal: do not use!
  - setBatchable
```
protected void setBatchable(IlvBatchable batchable)
```
    Sets the batch modification delegate used by this adapter. Batch notifications sent by the data source are forwarded to this object.
    
    Internal: do not use!
  - startBatch
```
protected void startBatch()
```
    Tells the model temporarily not to send events. After this call, the model notification events are delayed until the next call to endBatch.
    This method ensures that the startBatch method of the model is called with the correct synchronization strategy; that is, in the event thread in a regular application.
    Note: The adapter needs a model for this method to work.
    Note: Use IlpAbstractDataSource.startBatch() instead.
    
    Since:
    
    JTGO 4.0

    IlpAbstractDataSource.startBatch(), endBatch()

  - endBatch
```
protected void endBatch()
```
    Tells the model that a temporary inhibition of events is terminated and sends the events buffered since the last call to startBatch.
    This method ensures that the endBatch method of the model is called with the correct synchronization strategy; that is, in the event thread in a regular application.
    Note:The adapter needs a model for this method to work.

    The synchronization strategy is obtained from the context.
  - testObject
```
protected boolean testObject(IlpObject ilpObject)
```
    Returns true if an object of the data source should be represented.
    By default, it returns true if there is no filtering or if the IlpObject passes through the filter and the excluded class list.

    Returns:
    
    Returns a new list with the business objects that will be root objects in the representation model.
    
    Internal: do not use!

```
    Will start representing objects if this was not being done and there is a model and a data source.
  - initializeRepresentationObjects
```
protected void initializeRepresentationObjects()
