public abstract class AbstractPhaseInterceptor<T extends Message>
extends Object
implements PhaseInterceptor<T>

Provides a starting point implementation for a interceptors that participate in phased message processing. Developers should extend from this class when implementing custom interceptors. Developers need to provide an implementation for handleMessage() and can override the handleFault() implementation. They should not override the other methods.

Constructor Detail

AbstractPhaseInterceptor

public AbstractPhaseInterceptor(String phase)

Instantiates the interceptor to live in a specified phase. The interceptor's id will be set to the name of the implementing class.

Parameters:

phase - the interceptor's phase

AbstractPhaseInterceptor

public AbstractPhaseInterceptor(String i,
                                String p)

Instantiates the interceptor with a specified id.

Parameters:

i - the interceptor's id

p - the interceptor's phase

AbstractPhaseInterceptor

public AbstractPhaseInterceptor(String phase,
                                boolean uniqueId)

Instantiates the interceptor and specifies if it gets a system determined unique id. If uniqueId is set to true the interceptor's id will be determined by the runtime. If uniqueId is set to false, the implementing class' name is used as the id.

Parameters:

phase - the interceptor's phase

uniqueId - true to have a unique ID generated

AbstractPhaseInterceptor

public AbstractPhaseInterceptor(String i,
                                String p,
                                boolean uniqueId)

Instantiates the interceptor with a specified id or with a system determined unique id. The specified id will be used unless uniqueId is set to true.

Parameters:

i - the interceptor's id

p - the interceptor's phase

uniqueId -

Method Detail

setBefore

public void setBefore(Collection<String> i)

Specifies that the current interceptor needs to be added to the interceptor chain before the specified collection of interceptors. This method replaces any existing list with the provided list.

Parameters:

i - a collection of interceptor ids

setAfter

public void setAfter(Collection<String> i)

Specifies that the current interceptor needs to be added to the interceptor chain after the specified collection of interceptors. This method replaces any existing list with the provided list.

Parameters:

i - a collection of interceptor ids

addBefore

public void addBefore(Collection<String> i)

Specifies that the current interceptor needs to be added to the interceptor chain before the specified collection of interceptors.

Parameters:

i - a collection of interceptor ids

addAfter

public void addAfter(Collection<String> i)

Specifies that the current interceptor needs to be added to the interceptor chain after the specified collection of interceptors.

Parameters:

i - a collection of interceptor ids

addBefore

public void addBefore(String i)

Specifies that the current interceptor needs to be added to the interceptor chain before the specified interceptor.

Parameters:

i - an interceptor id

addAfter

public void addAfter(String i)

Specifies that the current interceptor needs to be added to the interceptor chain after the specified interceptor.

Parameters:

i - an interceptor id

getAfter

public final Set<String> getAfter()

Description copied from interface: PhaseInterceptor
