## com.bea.content.paging
Interface IObjectFilter

All Superinterfaces
  com.bea.content.paging.internal.IFilter, com.bea.content.paging.internal.ITypeSupport

All Known Implementing Classes:
  CmBrowserFoldersControlImpl.CmBrowserObjectFilter

    public interface IObjectFilter

extends com.bea.content.paging.internal.IFilter, com.bea.content.paging.internal.ITypeSupport

Interface which allows custom filtering to use the entire object state, for specified Java types. This is in contrast to property filters, which only have access to individual properties.

An overview of custom sorting and filtering is provided in the package documentation at `com.bea.content.paging`.

NOTE: custom object filters are designed for small datasets (narrow queries returning a hundred or less objects). They may not scale well for large datasets.

Use this interface when you want to add support for filtering objects of a given type, such as com.bea.content.Node, in their entirety. If you need access to multiple fields when doing filtering, this might be a good choice. For example, you could use an object filter to filter on multiple properties on a com.bea.content.Node object at once.

Basically, this specifies a custom IFilter implementation defining IFilter.accept( ContentContext, Object objVal ) where objVal is the property container object value, NOT a property value. This implementation will apply for one or more Java types (such as Node, VirtualNode, etc).

A ObjectFilter could also be written to filter on multiple custom Node ObjectClass (type) properties.

Field Summary
`static ContextKey` | `OBJECT_FILTER_KEY` CONTEXT KEYS (optional) specifies an ordered List used for filtering.

Method Summary
`void` | `setState(ContentContext context, String filterString, Locale filterLocale)` called BEFORE the filter.accept() method is invoked, to configure the filter state

Field Detail

### OBJECT_FILTER_KEY

    static final ContextKey OBJECT_FILTER_KEY

  CONTEXT KEYS (optional) specifies an ordered List used for filtering. The IObjectFilter interface is used to add support for entire-object filtering.

  A single IObjectFilter can apply for a given type, such as Node. The first IObjectFilter in the list which applies for the specified type is the one used.

Method Detail

### setState

    void setState(ContentContext context,
                  String filterString,
                  Locale filterLocale)
                  throws RepositoryException

  called BEFORE the filter.accept() method is invoked, to configure the filter state

  Throws
    `RepositoryException`
