      • getIdName

        public final java.lang.String getIdName()
        Description copied from interface: Context
        Returns the current id name associated with this context. Contexts are placed into stacks by id, in a context manager. Null if the context is not assigned to an id. Contexts known by context managers are always assigned to an id.

        A default Id name should be defined in each specific context interface as a static final field with the name CONTEXT_ID. For example, see org.apache.derby.iapi.sql.compile.CompilerContext.CONTEXT_ID.

      • isLastHandler

        public boolean isLastHandler​(int severity)
        Description copied from interface: Context
        Return whether or not this context is the "last" handler for a the specified severity level. Previously, the context manager would march through all of the contexts in cleanupOnError() and call each of their cleanupOnError() methods. That did not work with server side JDBC, especially for a StatementException, because outer contexts could get cleaned up incorrectly. This functionality is specific to the Language system. Any non-language system contexts should return ExceptionSeverity.NOT_APPLICABLE_SEVERITY. NOTE: Both the LanguageConnectionContext and the JDBC Connection Context are interested in session level errors because they both have clean up to do. This method allows both of them to return false so that all such handlers under them can do their clean up.
