public class ValidatorFilter
extends CachedCollectionFilter

This filter uses a collection of validators to filter objects in the collection. Any object that fails one or more validations will not be included in the result.

setValidators

public void setValidators(CollectionObjectValidator[] pValidators)

Sets the array of validators that will be executed in succession to produce the final filtered results.

Returns the array of validators that will be executed in succession to produce the final filtered results.

generateContextKey

public java.lang.Object generateContextKey(java.util.Collection pUnfilteredCollection,
                                           java.lang.String pCollectionIdentifierKey,
                                           RepositoryItem pProfile)

Generates a context key.

Overrides:

generateContextKey in class CachedCollectionFilter

Returns:

a null context key.

shouldApplyFilter

public boolean shouldApplyFilter(java.util.Collection pUnfilteredCollection,
                                 java.lang.String pCollectionIdentifierKey,
                                 RepositoryItem pProfile)

Description copied from class: CachedCollectionFilter

This method is called by filterCollection prior to looking up the filtered collection in the cache or generating a new filtered collection. Implementations should use this method to bypass the filter when it doesn't apply to the current execution context. (e.g. a profile attribute has the wrong value etc.)

Overrides:

shouldApplyFilter in class CachedCollectionFilter

Parameters:

pUnfilteredCollection - the unfiltered collection

pCollectionIdentifierKey - the key param as passed to filterCollection

pProfile - the user profile

Returns:

true if there are any validators to execute

generateFilteredCollection

protected java.util.Collection generateFilteredCollection(java.util.Collection pUnfilteredCollection,
                                                          java.lang.String pCollectionIdentifierKey,
                                                          RepositoryItem pProfile)
                                                   throws FilterException

Called by the filterCollection method to generate the filtered collection. Each object in the collection is tested against all validators. If the object does not pass any validation it is not included in the filtered results.

Each validator is executed by calling its validateObjects method.

Overrides:

generateFilteredCollection in class CachedCollectionFilter

Parameters:

pUnfilteredCollection - the unfiltered collection

pCollectionIdentifierKey - the key the uniquely identifies the unfiltered collection.

pProfile - Repository item

Returns:

the filtered collection

Throws:

FilterException
