A thread consistency support systemprovides thread consistency from a Connector Application Program Interfacethat creates multiple threads to a Thread-dependent Connectorthat only allows a single thread to link to that connector for all operations on that connector. The system includes a Detection/Activation routinethat activates a Threading MetaConnector routinein response to the Detection/Activation routine identifying a multi-threaded applicationattempting to access a Thread-dependent Connector. The Threading MetaConnector routineinterfaces between the Connector Application Program Interfaceand the Thread-dependent Connector. The Threading MetaConnector routineestablishes a connection handle for a single internal threadwith the Thread-dependent Connectorthat is returned to the Connector Application Program Interfaceof a calling multi-threaded applicationin place of multiple requested thread connection handles. The connection handle is established in response to the Threading MetaConnector routine's receipt of multiple threadsfrom the Connector Application Program Interface. The thread consistency support systemensures that the same thread that initializes a connection from the Thread-dependent Connectoris used for all subsequent operations attempted by the multiple threadsfrom the applicationwith that connector.

Thread consistency support system and method

Automatically augmenting functionality in an application programming interface ('API') is provided by receiving from an application a request for functionality to be fulfilled by a first component implementing at least a portion of the functionality within the application programming interface. The first component is queried for the requested functionality. If an indication that the first component does not implement the requested functionality is received, the a search for an augmentation component that implements the requested functionality is initiated. If an augmentation component supplying the required functionality is found, the augmentation component is loaded to fulfill the request for functionality in place of the first component and used to respond to the request for functionality. Augmentation components provide a subset of the API's required functionality, thereby removing a limitation from API components (i.e., functionality completeness). Augmentation components may also be used to provide new functionality for the API to all existing components (i.e., functionality enhancement).

Automatic feature augmentation for component based application programming interfaces

A system and method for converting character sets stored in at least one database into different character sets. First, an Activity including a requesting object makes a request of a Link. The Link including a receiving object and a retrieving object receives the request and retrieves the corresponding data from the database. The retrieval process creates a 'stream' object from the data and a character set indicator. The stream object is transmitted to the Activity which processes the request. During processing, a request may be made of the stream object for the data in a particular character set. The stream object determines whether the retrieved character set matches the character set requested. If the data requires converting, the stream object, comprising a converting object converts the data into the target character set. The data is then presented to the requester in the target character set. If no conversion is necessary, the data is sent directly to the requestor.
