Parameters

objectID

Type: org.opendof.core.oalDOFObjectID
The identifier of the object. This must not be null. This may not be BROADCAST for the CONNECT-level interest.

interfaceID

Type: org.opendof.core.oalDOFInterfaceID
The interface of interest. This must not be null. This may not be WILDCARD for the CONNECT-level interest.

level

Type: org.opendof.core.oalDOFInterestLevel
The level of interest. This must not be null.

control

Type: org.opendof.core.oalDOFOperationControl
The Control to use for the request. May be null, which indicates default Control.

timeout

Type: SystemInt32
How long in milliseconds that the interest should remain active. During this period, the operationListener will be called as matching providers become available. Must be >= 0.

operationListener

Type: org.opendof.core.oalDOFSystemInterestOperationListener
The operationListener for receiving asynchronous notification. A null value means no operationListener will be called.

context

Type: SystemObject
Application context for the query. The context is returned with the operation when a operationListener is called. A value of null represents 'no context', but will be handled just like a non-null value.

Return Value
