Method Detail

createQueryComponent

protected Component createQueryComponent()

Description copied from class: AbstractTableLoadDialog

Specified by:

createQueryComponent in class AbstractTableLoadDialog

Returns:

query component

isReady

public boolean isReady()

Description copied from class: AbstractTableLoadDialog

Indicates whether the submit action should be enabled. The implementation should return true if the user should be allowed to submit the query, or false if the internal state of this dialogue is known to be incomplete in some way. Evaluation should be fast; the return does not need to provide a guarantee that a submitted query will suceed.

The default implementation returns true.

Returns:

false iff dialogue state is known to be incomplete

createTableLoader

public TableLoader createTableLoader()

Returns:

new table loader object
