Class ObjectImpl
- Object
The basic implementation of the CORBA Object. The most of the methods
delegate the functionality to the
Delegate
that can be replaced
by
_set_delegate(Delegate)
.
Request | _create_request(Context context, String operation, NVList parameters, NamedValue returns) - Create a request to invoke the method of this object.
|
Request | _create_request(Context context, String operation, NVList parameters, NamedValue returns, ExceptionList exceptions, ContextList ctx_list) - Create a request to invoke the method of this object, specifying
context list and the list of the expected exception.
|
Object | _duplicate() - Duplicate the object reference.
|
Delegate | _get_delegate() - Get vendor specific delegate, responsible for the implemented
functionality.
|
DomainManager[] | _get_domain_managers() - Retrieve the domain managers for this object.
|
Object | _get_interface_def() - Get the
InterfaceDef for this Object.
|
Policy | _get_policy(int a_policy_type) - Returns the
Policy , applying to this object.
|
int | _hash(int max) - Get the hashcode this object reference.
|
abstract String[] | _ids() - Get the array of interface repository ids, defining this object.
|
InputStream | _invoke(OutputStream output) - Invoke the operation.
|
boolean | _is_a(String idl_id) - Check if this object can be referenced by the given repository id.
|
boolean | _is_equivalent(Object other) - Return true if the other object references are equivalent, so far as
it is possible to determine this easily.
|
boolean | _is_local() - Returns true if the object is local.
|
boolean | _non_existent() - Determines if the server object for this reference has already
been destroyed.
|
ORB | _orb() - Provides the reference to ORB.
|
void | _release() - Free resoureces, occupied by this reference.
|
void | _releaseReply(InputStream stream) - Release the reply stream back to ORB after finishing reading the data
from it.
|
Request | _request(String method) - Create a request to invoke the method of this CORBA object.
|
OutputStream | _request(String method, boolean response_expected) - Create a request to invoke the method of this CORBA object.
|
void | _servant_postinvoke(ServantObject servant) - This method is always called after invoking the operation on the
local servant.
|
ServantObject | _servant_preinvoke(String method, Class<T> expected_type) - Returns a servant that should be used for this request.
|
void | _set_delegate(Delegate a_delegate) - Set the delegate, responsible for the implemented functionality.
|
Object | _set_policy_override(Policy[] policies, SetOverrideType how) - Returns a new object with the new policies either replacing or
extending the current policies, depending on the second parameter.
|
boolean | equals(Object other) - Check if this object is equal to another object.
|
String | toString() - Return the string representation of the passed object.

_create_request
public Request _create_request(Context context,
String operation,
NVList parameters,
NamedValue returns)
Create a request to invoke the method of this object.
- _create_request in interface Object
context
- a list of additional properties.operation
- the name of method to be invoked.parameters
- the method parameters.returns
- the container for tge method returned value.
_create_request
public Request _create_request(Context context,
String operation,
NVList parameters,
NamedValue returns,
ExceptionList exceptions,
ContextList ctx_list)
Create a request to invoke the method of this object, specifying
context list and the list of the expected exception.
- _create_request in interface Object
context
- a list of additional properties.operation
- the name of method to be invoked.parameters
- the method parameters.returns
- the container for tge method returned value.exceptions
- the list of the possible exceptions that the method
can throw.ctx_list
- the list of the context strings that need to be
resolved and send as a context instance.
_duplicate
public Object _duplicate()
Duplicate the object reference. This does not make much sense for
java platform and is just included for the sake of compliance with
CORBA APIs.
The method may return the object reference itself.
- _duplicate in interface Object
_get_delegate
public Delegate _get_delegate()
Get vendor specific delegate, responsible for the implemented
functionality.
_get_policy
public Policy _get_policy(int a_policy_type)
Returns the
Policy
, applying to this object.
- _get_policy in interface Object
a_policy_type
- a type of policy to be obtained.
- a corresponding Policy object.
BAD_PARAM
- if the policy of the given type is not
associated with this object, or if it is not supported by this ORB.
_hash
public int _hash(int max)
Get the hashcode this object reference. The same hashcode still
does not means that the references are the same. From the other
side, two different references may still refer to the same CORBA
object. The returned value must not change during the object
lifetime.
- _hash in interface Object
max
- the maximal value to return.
_ids
public abstract String[] _ids()
Get the array of interface repository ids, defining this object.
_is_a
public boolean _is_a(String idl_id)
Check if this object can be referenced by the given repository id.
- _is_a in interface Object
idl_id
- the repository id.
- true if the passed parameter is a repository id of this
CORBA object.
_is_equivalent
public boolean _is_equivalent(Object other)
Return true if the other object references are equivalent, so far as
it is possible to determine this easily.
- _is_equivalent in interface Object
other
- the other object reference.
- true if both references refer the same object, false
if they probably can refer different objects. Uses direct
comparison if the delegate has not been set.
_is_local
public boolean _is_local()
Returns true if the object is local.
- false, always (following 1.4 specs). Override to get
functionality.
_non_existent
public boolean _non_existent()
Determines if the server object for this reference has already
been destroyed.
- _non_existent in interface Object
- true if the object has been destroyed, false otherwise.
_orb
public ORB _orb()
Provides the reference to ORB.
_release
public void _release()
Free resoureces, occupied by this reference. The object implementation
is not notified, and the other references to the same object are not
affected.
- _release in interface Object
_releaseReply
public void _releaseReply(InputStream stream)
Release the reply stream back to ORB after finishing reading the data
from it.
_request
public Request _request(String method)
Create a request to invoke the method of this CORBA object.
- _request in interface Object
method
- the name of the method to invoke.
_request
public OutputStream _request(String method,
boolean response_expected)
Create a request to invoke the method of this CORBA object.
method
- the name of the method to invoke.response_expected
- specifies if this is one way message or the
response to the message is expected.
- the stream where the method arguments should be written.
_servant_postinvoke
public void _servant_postinvoke(ServantObject servant)
This method is always called after invoking the operation on the
local servant.
The default method returns without action.
_servant_preinvoke
public ServantObject _servant_preinvoke(String method,
Class<T> expected_type)
Returns a servant that should be used for this request.
The servant can also be casted to the expected type, calling the
required method directly.
method
- the operationexpected_type
- the expected type of the servant.
This implementation always returns null; override for different
behavior.
- the servant or null if the servant is not an expected type
of the method is not supported, for example, due security reasons.
_set_delegate
public void _set_delegate(Delegate a_delegate)
Set the delegate, responsible for the implemented functionality.
a_delegate
- a delegate, responsible for the implemented
functionality.
equals
public boolean equals(Object other)
Check if this object is equal to another object.
- equals in interface Object
other
- the other object to compare.
- true if the objects are equal.
toString
public String toString()
Return the string representation of the passed object.
- toString in interface Object
- the string representation.
