getResourceList

public IResourceList getResourceList()

Description copied from interface: IRendererStatus

returns an IResourceList that does not have to be equal to either the ITypedResourceList or the result of the getChildren method on the ICollection attribute. It may be different because of the sort and filter methods or any other operation the implementing class decides to perform. As an implementation rule, a new creation of IResource elements to fill this list should be avoided due to the performance overhead associated with that operation.

Specified by:

getResourceList in interface IRendererStatus

Returns:

an IResourceList that might be empty. Must not return null.

getSelectedResources

public IResourceList getSelectedResources()

Specified by:

getSelectedResources in interface IRendererStatus

Specified by:

setCurrentIndex in interface IRendererStatus

Throws:

WcmException

setFilter

public void setFilter(IResourceListFilter filter)

Description copied from interface: IRendererStatus

sets the class, that is used to filter out resources from the given parent-collection or the ITypedResourceList. A change of this parameter will result in a new filtering, if the filter method is called afterwards. The call of this method alone does not lead to a new filtering (and a reset of selected resources).

Specified by:

setFilter in interface IRendererStatus

Parameters:

filter - the filter instance to use, can be null

setFilterParameters

public void setFilterParameters(IParameters filterparameters)

Description copied from interface: IRendererStatus

sets the parameters, that are used by the IResourceListFilter to determine which resources are to be filtered out. A change of this parameter will result in a new filtering, if the filter method is called afterwards. The call of this method alone does not lead to a new filtering (and a reset of selected resources).

Specified by:

setFilterParameters in interface IRendererStatus

Parameters:

filterparameters - determine which rules apply to filtering, can be null

setParent

public void setParent(ICollection parent)
               throws WcmException

Description copied from interface: IRendererStatus

sets the collection whose children are to be handled within this status. Any filtering of these children can only be done via the filter method of this status. If this method is called, the status will throw away all selection information and recreate its internal list of resources. The setTypedResourceList shows a similar behavior. Must not be null.

Specified by:

setParent in interface IRendererStatus

Throws:

WcmException

setPropertyColumns

public void setPropertyColumns(IPropertyColumn[] columns)

Description copied from interface: IRendererStatus

TODO what about null? sets the IPropertyColumn[] attribute of the status. Might be null.

Specified by:

setPropertyColumns in interface IRendererStatus

setSortDefinition

public void setSortDefinition(SortDefinition sd)

Description copied from interface: IRendererStatus

                          throws WcmException

Description copied from interface: IRendererStatus

sets the ITypedResourceList, whose elements are handled within this status. Must not be null but might be of size 0. The second parameter, the context, is needed to set the IResourceContext attribute of the status. This is normally retrieved from an IResource within the list, but the list might be empty.

Specified by:

setTypedResourceList in interface IRendererStatus

Throws:

WcmException

sort

public void sort()

Description copied from interface: IRendererStatus

sorts the internal list of resources. It uses the ResourcePropertyComparator attribute to do this sorting. If that attribute is null, no sorting will be done and the list will be sorted as it was before this method was called.

Description copied from interface: IMassDataControlStatus

returns the number of entries that are managed within this status

Specified by:

entrySize

getFieldSet

Parameters:

index - TBD: Description of the incoming method parameter

Returns:

fieldSet
