Method Details

setSavePoint

public int setSavePoint(String name,
 Object kindOfSavepoint)
                 throws StandardException

Savepoints are not supported in internal transactions.

Specified by:

setSavePoint in interface Transaction

Parameters:

name - The user provided name of the savepoint

kindOfSavepoint - A NULL value means it is an internal savepoint (ie not a user defined savepoint) Non NULL value means it is a user defined savepoint which can be a SQL savepoint or a JDBC savepoint A String value for kindOfSavepoint would mean it is SQL savepoint A JDBC Savepoint object value for kindOfSavepoint would mean it is JDBC savepoint

Returns:

returns total number of savepoints in the stack.

Throws:

StandardException - A transaction exception is thrown to disallow savepoints.

• Transaction.setSavePoint(String, Object)

checkLogicalOperationOk

public void checkLogicalOperationOk()
                             throws StandardException

Internal transactions don't allow logical operations.

Overrides:

doComplete

protected void doComplete(Integer commitOrAbort)
                   throws StandardException
