Method Summary

Modifier and Type	Method	Description
protected Collection<? extends org.microbean.attributes.Attributes>	interceptorBindings(Collection<? extends org.microbean.attributes.Attributes> as)	Given a Collection of Attributess, returns an immutable Collection consisting of those Attributes instances that are deemed to be interceptor bindings.
final boolean	test(Collection<? extends org.microbean.attributes.Attributes> receiverAttributes, Collection<? extends org.microbean.attributes.Attributes> payloadAttributes)	Returns true if and only if either (a) both the collection of interceptor bindings present in receiverAttributes and the collection of interceptor bindings present in payloadAttributes are empty, or (b) if the collection of interceptor bindings present in payloadAttributes has only one element and that element is the any interceptor binding, or (c) the sizes of the collection of interceptor bindings present in receiverAttributes and the collection of interceptor bindings present in payloadAttributes are the same and the collection of interceptor bindings present in receiverAttributes contains all the collection of interceptor bindings present in payloadAttributes and the collection of interceptor bindings present in payloadAttributes contains all the collection of interceptor bindings present in receiverAttributes.
final boolean	test(org.microbean.assign.AttributedType t, Id id)	Calls the test(Collection, Collection) method with the supplied AttributedType's attributes and the supplied Id's attributes and returns the result.

InterceptorBindingsMatcher

public InterceptorBindingsMatcher()

Creates a new InterceptorBindingsMatcher.

Method Details

test

public final boolean test(Collection<? extends org.microbean.attributes.Attributes> receiverAttributes,
 Collection<? extends org.microbean.attributes.Attributes> payloadAttributes)

Returns true if and only if either (a) both the collection of interceptor bindings present in receiverAttributes and the collection of interceptor bindings present in payloadAttributes are empty, or (b) if the collection of interceptor bindings present in payloadAttributes has only one element and that element is the any interceptor binding, or (c) the sizes of the collection of interceptor bindings present in receiverAttributes and the collection of interceptor bindings present in payloadAttributes are the same and the collection of interceptor bindings present in receiverAttributes contains all the collection of interceptor bindings present in payloadAttributes and the collection of interceptor bindings present in payloadAttributes contains all the collection of interceptor bindings present in receiverAttributes.

Parameters:

receiverAttributes - a Collection of Attributess; must not be null

payloadAttributes - a Collection of Attributess; must not be null

Returns:

true if and only if either (a) both the collection of interceptor bindings present in receiverAttributes and the collection of interceptor bindings present in payloadAttributes are empty, or (b) if the collection of interceptor bindings present in payloadAttributes has only one element and that element is the any interceptor binding, or (c) the sizes of the collection of interceptor bindings present in receiverAttributes and the collection of interceptor bindings present in payloadAttributes are the same and the collection of interceptor bindings present in receiverAttributes contains all the collection of interceptor bindings present in payloadAttributes and the collection of interceptor bindings present in payloadAttributes contains all the collection of interceptor bindings present in receiverAttributes

Throws:

NullPointerException - if either receiverAttributes or payloadAttributes is null

test

public final boolean test(org.microbean.assign.AttributedType t,
 Id id)

Calls the test(Collection, Collection) method with the supplied AttributedType's attributes and the supplied Id's attributes and returns the result.

Specified by:

test in interface BiPredicate<org.microbean.assign.AttributedType, Id>

Specified by:

test in interface org.microbean.assign.Matcher<org.microbean.assign.AttributedType, Id>

Parameters:

t - an AttributedType; must not be null

id - an Id; must not be null

Returns:

the result of calling the test(Collection, Collection) method with the supplied AttributedType's attributes and the supplied Id's attributes

interceptorBindings

protected Collection<? extends org.microbean.attributes.Attributes> interceptorBindings(Collection<? extends org.microbean.attributes.Attributes> as)

Given a Collection of Attributess, returns an immutable Collection consisting of those Attributes instances that are deemed to be interceptor bindings.

The default implementation of this method returns the value of an invocation of the InterceptorBindings.interceptorBindings(Collection) method.

Parameters:

as - a Collection; must not be null

Returns:

a List of interceptor bindings; never null

Throws:

NullPointerException - if as is null
