All Implemented Interfaces:

Serializable, Iterable<T>, Filtering<T>, org.primefaces.model.SelectableDataModel<T>

public abstract class AbstractLazyModel<T extends EntityInterface>
extends org.primefaces.model.LazyDataModel<T>
implements Filtering<T>

Class to support generic lazy loading of data and generic filtering support. The prevered usage is to create a managed bean of a subclass and provide that as an argument to AbstractLazyController.AbstractLazyController(java.lang.Class, org.fryske_akademy.jsf.lazy.AbstractLazyModel) using JsfUtil.findInContext(java.lang.String, java.lang.Class).

getLazyController

public AbstractLazyController getLazyController()

setLazyController

public final void setLazyController(AbstractLazyController lazyController)

Called in @Postconstruct of AbstractLazyController

Parameters:

lazyController -

getCrudReadService

public final CrudReadService getCrudReadService()

getRowData

public T getRowData(String rowKey)

Calls CrudReadService.find(java.io.Serializable, java.lang.Class) with Integer.valueOf(rowKey)

Specified by:

getRowData in interface org.primefaces.model.SelectableDataModel<T extends EntityInterface>

Parameters:

rowKey -

Returns:

initParamBuilder

protected Param.Builder initParamBuilder()

creates a Param.Builder using AbstractLazyController.isSyntaxInvalue() and Param.Builder.DEFAULT_MAPPING.

Returns:

convertFilters

protected final List<Param> convertFilters(Map<String,Object> filters)

Call initParamBuilder() and call addToParamBuilder(org.fryske_akademy.ejb.Param.Builder, java.lang.String, java.lang.Object) for each entry.
