Field Details

log

@Nonnull
private final org.slf4j.Logger log

Class logger.

transcodingRegistry

@Nonnull
private final Map<String,Multimap<Class<?>,TranscodingRule>> transcodingRegistry

Registry of transcoding instructions for a given "name" and type of object.

displayNameRegistry

@Nonnull
private final Map<String,Map<Locale,String>> displayNameRegistry

Registry of display name mappings associated with internal attribute IDs.

descriptionRegistry

@Nonnull
private final Map<String,Map<Locale,String>> descriptionRegistry

Registry of description mappings associated with internal attribute IDs.

namingFunctionRegistry

@Nonnull
private final Map<Class<?>,Function<?,String>> namingFunctionRegistry

Registry of naming functions for supported object types.

extendedConditionFactory

@Nullable
private Function<Map<String,Object>,Predicate<ProfileRequestContext>> extendedConditionFactory

Optional factory function for building extended activation conditions.

applicationContext

@Nullable
private ApplicationContext applicationContext

The context used to load this bean.

Constructor Details

AttributeTranscoderRegistryImpl

public AttributeTranscoderRegistryImpl()

Constructor.

Method Details

setApplicationContext

public void setApplicationContext(@Nullable
 ApplicationContext context)

Specified by:

setApplicationContext in interface ApplicationContextAware

getApplicationContext

@Nullable
public ApplicationContext getApplicationContext()

Get the context used to load this bean.

Returns:

the context.

setNamingRegistry

public void setNamingRegistry(@Nullable
 Collection<AttributeTranscoderRegistry.NamingFunction<?>> registry)

Installs registry of naming functions mapped against the types of objects they support.

Parameters:

registry - collection of naming functions for indexing

setTranscoderRegistry

public void setTranscoderRegistry(@Nonnull
 Collection<TranscodingRule> mappings)

Installs the transcoder mappings en masse.

Each map connects an IdPAttribute name to the rules for transcoding to/from it.

The rules MUST contain at least:

• AttributeTranscoderRegistry.PROP_ID - internal attribute ID to map to/from
• AttributeTranscoderRegistry.PROP_TRANSCODER - an AttributeTranscoder instance supporting the type

Transcoders will generally require particular properties in their own right to function.

Parameters:

mappings - transcoding rulesets

setExtendedConditionFactory

public void setExtendedConditionFactory(@Nullable
 Function<Map<String,Object>,Predicate<ProfileRequestContext>> factory)

Set a factory function to call to consume a rule set and produce an optional "extended" activation condition Predicate.

This allows deployments to define extended property names that represent condition types not known to this layer of the code base.

Parameters:

factory - factory function

getDisplayNames

@Nonnull
@NotLive
@Unmodifiable
public Map<Locale,String> getDisplayNames(@Nonnull
 IdPAttribute attribute)

Specified by:

getDisplayNames in interface AttributeTranscoderRegistry

getDescriptions

@Nonnull
@NotLive
@Unmodifiable
public Map<Locale,String> getDescriptions(@Nonnull
 IdPAttribute attribute)

Specified by:

getDescriptions in interface AttributeTranscoderRegistry

getTranscodingRules

@Nonnull
@Unmodifiable
@NotLive
public Collection<TranscodingRule> getTranscodingRules(@Nonnull
 IdPAttribute from,
 @Nonnull
 Class<?> to)

Specified by:

getTranscodingRules in interface AttributeTranscoderRegistry

getTranscodingRules

@Nonnull
@Unmodifiable
@NotLive
public <T> Collection<TranscodingRule> getTranscodingRules(@Nonnull
 T from)

Specified by:

getTranscodingRules in interface AttributeTranscoderRegistry

getAttributeTranscoders

@Nonnull
private Collection<AttributeTranscoder<?>> getAttributeTranscoders(@Nonnull
 TranscodingRule rule)

Get the appropriate AttributeTranscoder objects to use.

Parameters:

rule - transcoding rule

Returns:

transcoders to install under a copy of each ruleset's AttributeTranscoderRegistry.PROP_TRANSCODER property

addMapping

private void addMapping(@Nonnull @NotEmpty
 String id,
 @Nonnull
 AttributeTranscoder<?> transcoder,
 @Nonnull
 Map<String,Object> ruleset)

Add a mapping between an IdPAttribute name and a set of transcoding rules.

Parameters:

id - name of the IdPAttribute to map to/from

transcoder - the transcoder for this rule

ruleset - transcoding rules

buildActivationCondition

@Nullable
private Predicate<ProfileRequestContext> buildActivationCondition(@Nonnull
 Map<String,Object> ruleset)

Build an appropriate Predicate to use as an activation condition within the ruleset.

Parameters:

ruleset - transcoding rules

Returns:

a predicate to install under the ruleset's AttributeTranscoderRegistry.PROP_CONDITION

getEffectiveType

@Nullable
private Class<?> getEffectiveType(@Nonnull
 Class<?> inputType)

Convert an input type into the appropriate type (possibly itself) to use in looking up rules in the registry.

Parameters:

inputType - the type passed into the registry operation

Returns:

the appropriate type to use subsequently or null if not found
