canInvoke

public boolean canInvoke(MBeanServer mbeanServer,
                ObjectName objectName)
                  throws JMException,
                         IOException

Returns whether there is any method that the current user can invoke.

Parameters:

mbeanServer - the MBeanServer where the object is registered.

objectName - the ObjectName to check.

Returns:

true if there is a method on the object that can be invoked, false else.

Throws:

JMException

IOException

canInvoke

public boolean canInvoke(BulkRequestContext context,
                MBeanServer mbeanServer,
                ObjectName objectName)
                  throws JMException,
                         IOException

Returns whether there is any method that the current user can invoke.

Parameters:

context - BulkRequestContext for optimized ConfigAdmin access, may be null

mbeanServer - the MBeanServer where the object is registered.

objectName - the ObjectName to check.

Returns:

true if there is a method on the object that can be invoked, false else.

Throws:

JMException

IOException

canInvoke

public boolean canInvoke(MBeanServer mbeanServer,
                ObjectName objectName,
                String methodName)
                  throws JMException,
                         IOException

Returns whether there is any overload of the specified method that can be invoked by the current user.

Parameters:

mbeanServer - the MBeanServer where the object is registered.

objectName - the MBean ObjectName.

methodName - the name of the method.

Returns:

true if there is an overload of the method that can be invoked by the current user.

Throws:

JMException

IOException

canInvoke

public boolean canInvoke(BulkRequestContext context,
                MBeanServer mbeanServer,
                ObjectName objectName,
                String methodName)
                  throws JMException,
                         IOException

Returns whether there is any overload of the specified method that can be invoked by the current user.

Parameters:

context - BulkRequestContext for optimized ConfigAdmin access, may be null

mbeanServer - the MBeanServer where the object is registered.

objectName - the MBean ObjectName.

methodName - the name of the method.

Returns:

true if there is an overload of the method that can be invoked by the current user.

Throws:

JMException

IOException

canInvoke

public boolean canInvoke(MBeanServer mbeanServer,
                ObjectName objectName,
                String methodName,
                String[] signature)
                  throws IOException

Returns true if the method on the MBean with the specified signature can be invoked.

Parameters:

mbeanServer - the MBeanServer where the object is registered.

objectName - the MBean ObjectName.

methodName - the name of the method.

signature - the signature of the method.

Returns:

true if the method can be invoked, false else. Note that if a method name or signature is provided that does not exist on the MBean, the behaviour of this method is undefined. In other words, if you ask whether a method that does not exist can be invoked, the method may return true but actually invoking that method will obviously not work.

Throws:

IOException

canInvoke

public boolean canInvoke(BulkRequestContext context,
                MBeanServer mbeanServer,
                ObjectName objectName,
                String methodName,
                String[] signature)
                  throws IOException

Returns true if the method on the MBean with the specified signature can be invoked.

Parameters:

context - BulkRequestContext for optimized ConfigAdmin access, may be null

mbeanServer - the MBeanServer where the object is registered.

objectName - the MBean ObjectName.

methodName - the name of the method.

signature - the signature of the method.

Returns:

true if the method can be invoked, false else. Note that if a method name or signature is provided that does not exist on the MBean, the behaviour of this method is undefined. In other words, if you ask whether a method that does not exist can be invoked, the method may return true but actually invoking that method will obviously not work.

Throws:
