Constructor Detail

ConstructorCalledByMethodInvocationWrapper

                                          Interceptor[] interceptors)

Method Detail

getMetaData

public Object getMetaData(Object group,
                 Object attr)

Description copied from class: ConstructorCalledByMethodInvocation

This method resolves metadata based on the context of the invocation. It iterates through its list of MetaDataResolvers to find out the value of the metadata desired.

This list usually is ThreadMetaData, InstanceAdvisor.getMetaData ClassAdvisor.getMethodMetaData (or field, or constructor) ClassAdvisor.getDefaultMetaData

Specified by:

getMetaData in interface Invocation

Overrides:

getMetaData in class ConstructorCalledByMethodInvocation

invokeNext

public Object invokeNext()
                  throws Throwable

Description copied from class: ConstructorCalledByMethodInvocation

Invoke on the next interceptor in the chain. If this is already the end of the chain, reflection will call the constructor, field, or method you are invoking on.

Specified by:

invokeNext in interface Invocation

Overrides:

invokeNext in class ConstructorCalledByMethodInvocation

Throws:

Throwable

getInstanceResolver

public MetaDataResolver getInstanceResolver()

Overrides:

getInstanceResolver in class InvocationBase

getCallingClass

public Class<?> getCallingClass()

Overrides:

getCallingClass in class ConstructorCalledByMethodInvocation

Returns:

The class that is making the call on the constructor

getCallingMethod

public Method getCallingMethod()

Overrides:

getCallingMethod in class ConstructorCalledByMethodInvocation

Returns:

The method that is making the call on the constructor

getCalledConstructor

public Constructor<?> getCalledConstructor()

Overrides:

getCalledConstructor in class ConstructorCalledByMethodInvocation

Returns:

the constructor call being executed by the calling method

isWrapped

public boolean isWrapped()

Description copied from class: ConstructorCalledByMethodInvocation

Is the called constructor aspectized? If so then there is a wrapping method that must be called.

Overrides:

isWrapped in class ConstructorCalledByMethodInvocation

Returns:

true if the constructor is wrapped

getWrappingMethod

public Method getWrappingMethod()

Description copied from class: ConstructorCalledByMethodInvocation

Is the called constructor aspectized? If so then this method returns the method that wraps the constructor.

Overrides:

getWrappingMethod in class ConstructorCalledByMethodInvocation

Returns:

the method that wraps the constructor if ConstructorCalledByMethodInvocation.isWrapped() returns true; null otherwise.

copy

public Invocation copy()

Description copied from class: ConstructorCalledByMethodInvocation

Copies complete state of Invocation object.

Specified by:

copy in interface Invocation

Overrides:

copy in class ConstructorCalledByMethodInvocation

Returns:

a copy of this instance

getAdvisor

public Advisor getAdvisor()

Specified by:

getAdvisor in interface Invocation

Overrides:

getAdvisor in class InvocationBase

getTargetObject

public Object getTargetObject()

Specified by:

getTargetObject in interface Invocation

Overrides:

getTargetObject in class InvocationBase

setTargetObject

public void setTargetObject(Object targetObject)

Specified by:

setTargetObject in interface Invocation

Overrides:

setTargetObject in class InvocationBase

getResponseContextInfo

public Map<Object,Object> getResponseContextInfo()

Specified by:

getResponseContextInfo in interface Invocation

Overrides:

getResponseContextInfo in class InvocationBase

setResponseContextInfo

public void setResponseContextInfo(Map<Object,Object> responseContextInfo)

Specified by:

setResponseContextInfo in interface Invocation

Overrides:

setResponseContextInfo in class InvocationBase

addResponseAttachment

public void addResponseAttachment(Object key,
                         Object val)

Specified by:

addResponseAttachment in interface Invocation

Overrides:

addResponseAttachment in class InvocationBase

getResponseAttachment

public Object getResponseAttachment(Object key)

Specified by:

getResponseAttachment in interface Invocation

Overrides:

getResponseAttachment in class InvocationBase

getMetaData

public SimpleMetaData getMetaData()

Description copied from class: InvocationBase

Return all the contextual data attached to this invocation

Specified by:

getMetaData in interface Invocation

Overrides:

getMetaData in class InvocationBase

setMetaData

public void setMetaData(SimpleMetaData data)

Description copied from class: InvocationBase

Set all the contextual data attached to this invocation

Specified by:

setMetaData in interface Invocation

Overrides:

setMetaData in class InvocationBase

getArguments

public Object[] getArguments()

Description copied from class: CallerInvocation

Returns a non-null array containing all call arguments.

The returned array can be changed by the advice or interceptor accordingly. All changes are reflected on joinpoint execution, and are noticed as well by other advices and interceptors that are executed after the current one.
However, changes to this array are limited to the scope of current advice execution, and must be performed before execution of InvocationBase.invokeNext(), InvocationBase.invokeNext(Interceptor[]), or InvocationBase.invokeTarget() method. Otherwise, inconsistency on joinpoint argument values may be noticed.

Overrides:

getArguments in class CallerInvocation

Returns:

the call arguments

setArguments

public void setArguments(Object[] arguments)

Description copied from class: CallerInvocation

Replaces call argument values by the ones contained in arguments.

Advices and interceptors must be aware that, for performance reasons, this array does not get copied across; its reference is directly used instead. Hence, changes to arguments array after this method being called are forbidden. Otherwise, inconsistency on joinpoint argument values may be noticed.

Overrides:

setArguments in class CallerInvocation

Parameters:

arguments - a non-null array containing the new values of call arguments. The size of this array must be the same as the one of CallerInvocation.getArguments(), as well as the element types.
