com.bea.content.paging
Interface ContentListKeys

All Known Subinterfaces:

IFilterablePagedList<T>, IPagedList<T>, ISortableFilterablePagedList<T>, ISortablePagedList<T>

public interface ContentListKeys

Common context keys which can be used across CMPagedResult and IPagedList result collection types.

These keys are used in conjunction with various methods on the I*Manager classes which return ISortableFilterablePagedList objects. The methods which return the paged list objects can do sorting and filtering. Depending on the repository's implementation the sorting and filtering may be done "natively" (within the repository prior to returning the results) or "non-natively" (within the VCR itself, in-memory.) The list of native sortable and filterable properties may be found in the documentation for those objects (Node, VirtualNode, ObjectClass, Version and Workflow).

For the WLP Repository, the native sortable and filterable properties are documented below. For other repositories, see their SPI documentation.

Additional information about the paging system can be found in the package documentation at com.bea.content.paging.

This interface is intended to be implemented only by Oracle Weblogic Portal. Oracle Systems reserves the right to add abstract methods to this interface without notice. Implementations of this interface by other parties must not be expected to compile without change in future versions of Oracle Weblogic Portal.

Field Summary

static Integer	ALL_ITEMS Special size to indicate all items.
static ContextKey	BATCH_LOADING_SIZE_KEY Optional ContextKey which can be placed in the ContentContext specifies the batch loading size to use when items are retrieved.
static String	CUSTOM_OBJECT_FILTER Special property name which can be used when filtering to request an object filter (not a per-property filter).
static String	CUSTOM_OBJECT_SORT Special property name which can be used when sorting to request an object sort (not a per-property sort).
static ContextKey	FILTER_CRITERIA_KEY Optional ContextKey which can be placed in the ContentContext specifies that filtering should be used when fetching data, and specifies the FilterCriteria objects to use.
static ContextKey	SORT_CRITERIA_KEY Optional ContextKey which can be placed in the ContentContext specifies that sorting should be used when fetching data, and specifies the SortCriteria objects to use.

Field Detail

ALL_ITEMS

static final Integer ALL_ITEMS

Special size to indicate all items.

This size can be used when specifying a batch size.

See Also

When specified as a batch size, this causes all items to be loaded initially rather than on demand. One reason you might want to do this is if you know you will need to access every item, and you know you can safely load all items into memory.

BATCH_LOADING_SIZE_KEY

static final ContextKey BATCH_LOADING_SIZE_KEY

Optional ContextKey which can be placed in the ContentContext specifies the batch loading size to use when items are retrieved. If not specified, a default value will be used

CUSTOM_OBJECT_SORT

static final String CUSTOM_OBJECT_SORT

Special property name which can be used when sorting to request an object sort (not a per-property sort). Use this property name when calling creating a SortCriteria or calling ISortablePagedList.reSort(com.bea.p13n.pagination.SortOrder, String, java.util.Locale), if you want to sort using a custom object sorter.

The custom object sorter must be specified in the ContentContext.

Constants Summary

CUSTOM_OBJECT_FILTER

static final String CUSTOM_OBJECT_FILTER

Special property name which can be used when filtering to request an object filter (not a per-property filter). Use this property name when calling creating a FilterCriteria or calling IFilterablePagedList.reFilter(com.bea.p13n.pagination.FilterMethod, String, String, java.util.Locale), if you want to filter using a custom object filter.

The custom object filter must be specified in the ContentContext.

Constants Summary

SORT_CRITERIA_KEY

static final ContextKey SORT_CRITERIA_KEY

Optional ContextKey which can be placed in the ContentContext specifies that sorting should be used when fetching data, and specifies the SortCriteria objects to use. A single SortCriteria is allowed.

Native sortable properties for the WLP Repository are found via the ISortablePagedList.getNativeSortableProperties() method. This is dependent upon the items found in the list. See the javadoc for those objects for their native sortable properties.

FILTER_CRITERIA_KEY

static final ContextKey FILTER_CRITERIA_KEY

Optional ContextKey which can be placed in the ContentContext specifies that filtering should be used when fetching data, and specifies the FilterCriteria objects to use. A single FilterCriteria is allowed.

Native filterable properties for the WLP Repository are found via the IFilterablePagedList.getNativeFilterableProperties() method. This is dependent upon the items found in the list. See the javadoc for those objects for their native filterable properties.

Filter methods may be found via the IFilterablePagedList.getAllFilterMethods() method.
