javax.resource API 1.7.1 · javax.resource.spi.work.ExecutionContext

This class models an execution context (transaction, security, etc) with which the Work instance must be executed. This class is provided as a convenience for easily creating ExecutionContext instances by extending this class and overriding only those methods of interest.

Some reasons why it is better for ExecutionContext to be a class rather than an interface:

There is no need for a resource adapter to implement this class. It only needs to implement the context information like transaction, etc.
The resource adapter code does not have to change when the ExecutionContext class evolves. For example, more context types could be added to the ExecutionContext class (in the future) without forcing resource adapter implementations to change.

Note

Resource adapters that are developed for Connectors 1.6 specification compliant application servers and above, are recommended to use the TransactionContext interface instead of this class. See Chapter.11 Generic Work Context in the Connectors 1.6 specification for more details.

Method Summary

Modifier and Type	Method and Description
public long	Returns: the specified transaction timeout value in seconds. When no timeout value or an illegal timeout value had been specified, a value of -1 (`WorkManager.UNKNOWN`) is returned; the timeout processing of such a transaction depends on the application server implementation. getTransactionTimeout() Get the transaction timeout value for a imported transaction.
public Xid	Returns: an Xid object carrying a transaction context, if any. getXid()
public void	setTransactionTimeout(long transaction timeout value in seconds. Only positive non-zero values are accepted. Other values are illegal and are rejected with a `NotSupportedException`. timeout) Set the transaction timeout value for a imported transaction.
public void	setXid(Xid transaction context. xid) set a transaction context.

getTransactionTimeout	back to summary
public long getTransactionTimeout() Get the transaction timeout value for a imported transaction. Returns:long the specified transaction timeout value in seconds. When no timeout value or an illegal timeout value had been specified, a value of -1 (`WorkManager.UNKNOWN`) is returned; the timeout processing of such a transaction depends on the application server implementation.

public long getTransactionTimeout()

Get the transaction timeout value for a imported transaction.

Returns:long: the specified transaction timeout value in seconds. When no timeout value or an illegal timeout value had been specified, a value of -1 (WorkManager.UNKNOWN) is returned; the timeout processing of such a transaction depends on the application server implementation.
