All Implemented Interfaces:

public class EntityAttributesFilter
extends AbstractInitializableComponent
implements MetadataFilter

A filter that adds EntityAttributes extension content to entities in order to drive software behavior based on them.

The entities to annotate are identified with a Predicate, and multiple attributes can be associated with each.

As of 3.4.0, another predicate can be set to validate pre-existing extension content to better protect use cases of this component.

Method Details

setRules

public void setRules(@Nonnull @NonnullElements
Map<Predicate<EntityDescriptor>,Collection<Attribute>> rules)

Set the mappings from Predicate to Attribute collection to apply.

Parameters:

rules - rules to apply

setAttributeFilter

public void setAttributeFilter(@Nullable
Predicate<Attribute> condition)

Set a condition to apply to any pre-existing extension attributes, such that failure causes their removal.

If not set, then anything is allowed.

Parameters:

condition - condition to apply

Since:

3.4.0

filter

@Nullable
public XMLObject filter(@Nullable
XMLObject metadata,
@Nonnull
MetadataFilterContext context)
                 throws FilterException

Filters the given metadata, perhaps to remove elements that are not wanted.

Specified by:

filter in interface MetadataFilter

Parameters:

metadata - the metadata to be filtered.

context - the metadata filter context

Returns:

the filtered XMLObject, which may or may not be the same as the XMLObject instance passed in to the method. Maybe be null, for example if the top-level element was removed by the filter.

Throws:

FilterException - thrown if an error occurs during the filtering process

filterEntityDescriptor

protected void filterEntityDescriptor(@Nonnull
EntityDescriptor descriptor)

Filters entity descriptor.

Parameters:

descriptor - entity descriptor to filter

filterEntitiesDescriptor

protected void filterEntitiesDescriptor(@Nonnull
EntitiesDescriptor descriptor)

Filters entities descriptor.

Parameters:

descriptor - entities descriptor to filter

addEntityAttribute

@Nonnull
private void addEntityAttribute(@Nonnull
EntityDescriptor descriptor,
@Nonnull
EntityAttributes container,
@Nonnull
Attribute input)

Get or create Attribute based on the input/template object.

Parameters:

descriptor - parent entity

container - extension container

input - input object

applyFilter

@Nullable
private void applyFilter(@Nonnull
EntityDescriptor descriptor)

Apply include policy to metadata on input.

Parameters:

descriptor - input to evaluate
