Interface IEnvironment

Deprecated. As of UDK 3.2, this interface is deprecated, without offering a replacement.

public interface IEnvironment

The interface implemented by UNO environments.

With this interface, objects can be registered at and revoked from an environment.

See Also:

IBridge, IQueryInterface, UnoRuntime

Method Summary

Object	getContext() Deprecated. Gets the context of this environment.
String	getName() Deprecated. Gets the name of this environment.
Object	getRegisteredInterface(String oid, Type type) Deprecated. Retrieves a registered object, specified by OID and UNO interface type.
String	getRegisteredObjectIdentifier(Object object) Deprecated. Retrieves the OID for a registered object.
void	list() Deprecated. Lists the registered objects to System.out.
Object	registerInterface(Object object, String[] oid, Type type) Deprecated. Registers one UNO interface facet of an object.
void	revokeInterface(String oid, Type type) Deprecated. Explicitly revokes a UNO interface facet.

Method Detail

getContext

Object getContext()

Deprecated.

Gets the context of this environment.

Returns:

the context of this environment

getName

String getName()

Deprecated.

Gets the name of this environment.

Returns:

the name of this environment

registerInterface

Object registerInterface(Object object,
                         String[] oid,
                         Type type)

Deprecated.

Registers one UNO interface facet of an object.

Such an object will typically be one of three things:

• A local Java object, to be mapped out of this environment via a given bridge.
• A proxy object, mapped into this environment via some bridge B1, and now to be mapped out of this environment via a given bridge B2.
• A proxy object, created as a remote object is mapped into this environment via a given bridge.

The object actually registered may differ from the specified object that is passed as an argument. This enables an environment to work in a multi-threaded scenario, where two threads can call registerInterface for the same combination of oid and type at the same time; the race condition is solved by letting one of the calls register its argument object, ignoring the argument object of the other call, and letting both calls return the same object.

The registered object is held only weakly by the environment. After a call to registerInterface, a call to getRegisteredInterface only succeeds as long as the registered object is still strongly reachable, and the registered object has not been explicitly revoked by calling revokeInterface.

Parameters:

object - the object to register; must be non-null

oid - in-out parameter containing the OID of object. This must be a non-null reference to an array of length at least one; the zeroth element is used to pass the argument in and out. If the zeroth element is null on input, the OID will be computed and passed out (that is, the zeroth element will never be null upon normal return).

type - the UNO interface type to register. This argument must be non-null, and must denote a UNO interface type. The given object should implement this type.

Returns:

the registered object (may differ from the object passed in); will never be null

revokeInterface

void revokeInterface(String oid,
                     Type type)

Deprecated.

Explicitly revokes a UNO interface facet.

Calls to registerInterface and revokeInterface must be paired. A facet is only removed from the environment when it has been revoked as often as it has been registered. This may change in the future, so that a facet would be removed upon the first call to revokeInterface (and calls to revokeInterface would no longer be necessary if the calling code does not want to control the temporal extent of the registration).

It is not an error if the specified facet is not registered at this environment (either because no corresponding object has ever been registered, or it has been explicitly revoked, or it is no longer strongly reachable). In such a case, this method simply does nothing.

Parameters:

oid - the OID of the object to revoke; must be non-null

type - the UNO interface type of the object to revoke. This argument must be non-null, and must denote a UNO interface type.

getRegisteredInterface

Object getRegisteredInterface(String oid,
                              Type type)

Deprecated.

Retrieves a registered object, specified by OID and UNO interface type.

Parameters:

oid - the OID of the object to retrieve; must be non-null

type - the UNO interface type of the object to retrieve. This argument must be non-null, and must denote a UNO interface type.

Returns:

the registered object, or null if none is found

getRegisteredObjectIdentifier

String getRegisteredObjectIdentifier(Object object)

Deprecated.

Retrieves the OID for a registered object.

Parameters:

object - a registered object; must be non-null

Returns:

the OID of the object; will never be null

list

void list()

Deprecated.

Lists the registered objects to System.out.

This is for debug purposes.
