getInterceptors

public List<AsyncInterceptor> getInterceptors()

Specified by:

getInterceptors in interface AsyncInterceptorChain

Returns:

An immutable list of the current interceptors.

addInterceptor

public void addInterceptor(AsyncInterceptor interceptor,
                           int position)

Description copied from interface: AsyncInterceptorChain

Inserts the given interceptor at the specified position in the chain (0 based indexing).

Specified by:

addInterceptor in interface AsyncInterceptorChain

removeInterceptor

public void removeInterceptor(int position)

Description copied from interface: AsyncInterceptorChain

Removes the interceptor at the given position.

Specified by:

removeInterceptor in interface AsyncInterceptorChain

size

public int size()

Description copied from interface: AsyncInterceptorChain

Returns the number of interceptors in the chain.

Specified by:

size in interface AsyncInterceptorChain

removeInterceptor

public void removeInterceptor(Class<? extends AsyncInterceptor> clazz)

Description copied from interface: AsyncInterceptorChain

Removes all the occurrences of supplied interceptor type from the chain.

Specified by:

removeInterceptor in interface AsyncInterceptorChain

addInterceptorAfter

public boolean addInterceptorAfter(AsyncInterceptor toAdd,
                                   Class<? extends AsyncInterceptor> afterInterceptor)

Description copied from interface: AsyncInterceptorChain

Adds a new interceptor in list after an interceptor of a given type.

Specified by:

addInterceptorAfter in interface AsyncInterceptorChain

Returns:

true if the interceptor was added; i.e. the afterInterceptor exists

addInterceptorBefore

public boolean addInterceptorBefore(AsyncInterceptor toAdd,
                                    Class<? extends AsyncInterceptor> beforeInterceptor)

Description copied from interface: AsyncInterceptorChain

Adds a new interceptor in list before an interceptor of a given type.

Specified by:

addInterceptorBefore in interface AsyncInterceptorChain

Returns:

true if the interceptor was added; i.e. the beforeInterceptor exists

replaceInterceptor

public boolean replaceInterceptor(AsyncInterceptor replacingInterceptor,
                                  Class<? extends AsyncInterceptor> toBeReplacedInterceptorType)

Description copied from interface: AsyncInterceptorChain

Replaces an existing interceptor of the given type in the interceptor chain with a new interceptor instance passed as parameter.

Specified by:

replaceInterceptor in interface AsyncInterceptorChain

Parameters:

replacingInterceptor - the interceptor to add to the interceptor chain

toBeReplacedInterceptorType - the type of interceptor that should be swapped with the new one

Returns:

true if the interceptor was replaced

appendInterceptor

Note: Reusing the context for multiple invocations is allowed, however most context implementations are not thread-safe.

Specified by:

invoke in interface AsyncInterceptorChain
