Method Detail

invokeNext

protected Object invokeNext()
                     throws Exception

Throws:

Exception

interceptorChainCompleted

protected Object interceptorChainCompleted()
                                    throws Exception

Throws:

Exception

proceed

public Object proceed()
               throws Exception

Description copied from interface: InvocationContext

Proceed to the next interceptor in the interceptor chain. For around-invoke or around-timeout interceptor methods, the invocation of proceed in the last interceptor method in the chain causes the invocation of the target class method. For AroundConstruct lifecycle callback interceptor methods, the invocation of proceed in the last interceptor method in the chain causes the target instance to be created. For all other lifecycle callback interceptor methods, if there is no callback method defined on the target class, the invocation of proceed in the last interceptor method in the chain is a no-op.

Return the result of the next method invoked, or a null value if the method has return type void.

Specified by:

proceed in interface InvocationContext

Returns:

the return value of the next method in the chain

Throws:

Exception - if thrown by target method or interceptor method in call stack

getTarget

public Object getTarget()

Description copied from interface: InvocationContext

Returns the target instance. For AroundConstruct lifecycle callback interceptor methods, the getTarget method returns null if called before the InvocationContext.proceed() method.

Specified by:

getTarget in interface InvocationContext

Returns:

the target instance

getMethod

public Method getMethod()

Description copied from interface: InvocationContext

Returns the method of the target class for which the interceptor was invoked. Returns null in a lifecycle callback interceptor for which there is no corresponding lifecycle callback method declared in the target class (or inherited from a superclass) or in an AroundConstruct lifecycle callback interceptor method.

Specified by:

getMethod in interface InvocationContext

Returns:

the method, or a null value

getConstructor

public Constructor<?> getConstructor()

Description copied from interface: InvocationContext

Returns the constructor of the target class for which the AroundConstruct interceptor method was invoked. Returns null for interceptor method types other than AroundConstruct interceptor methods.

Specified by:

getConstructor in interface InvocationContext

Returns:

the constructor, or a null value

getParameters

public Object[] getParameters()
                       throws IllegalStateException

Description copied from interface: InvocationContext

Returns the parameter values that will be passed to the method or constructor of the target class. If InvocationContext.setParameters(java.lang.Object[]) has been called, getParameters returns the values to which the parameters have been set.

Specified by:

getParameters in interface InvocationContext

Returns:

the parameter values, as an array

Throws:

IllegalStateException - if invoked within a lifecycle callback method that is not an AroundConstruct callback.

setParameters

public void setParameters(Object[] params)
                   throws IllegalStateException,
                          IllegalArgumentException

Description copied from interface: InvocationContext

Sets the parameter values that will be passed to the method or constructor of the target class.

Specified by:

setParameters in interface InvocationContext

Parameters:

params - the parameter values, as an array

Throws:

IllegalStateException - if invoked within a lifecycle callback method that is not an AroundConstruct callback.

IllegalArgumentException - if the types of the given parameter values do not match the types of the method or constructor parameters, or if the number of parameters supplied does not equal the number of method or constructor parameters (if the last parameter is a vararg parameter of type T, it is considered to be equivalent to a parameter of type T[]).

getContextData

public Map<String,Object> getContextData()

Description copied from interface: InvocationContext

Enables an interceptor to retrieve or update the data associated with the invocation by another interceptor, business method, and/or webservices endpoint in the invocation chain. If interceptors are invoked as a result of the invocation on a web service endpoint, the returned value will be an instance of javax.xml.rpc.handler.MessageContext.

Specified by:

getContextData in interface InvocationContext

Returns:

the context data associated with this invocation or lifecycle callback. If there is no context data, an empty Map<String,Object> object will be returned.

getTimer

public Object getTimer()

Description copied from interface: InvocationContext

Returns the timer object associated with a timeout method invocation on the target class, or a null value for interceptor method types other than AroundTimeout. For example, when associated with an Jakarta Enterprise Beans component timeout, this method returns javax.ejb.Timer.

Specified by:

getTimer in interface InvocationContext

Returns:

the timer object or a null value
