getType

public String getType()

Description copied from class: QueryFactories.QueryTermFactory

The type is used as a hint so that the query term can be executed without having to make guesses about how to interpret it. When the query term is being created (e.g. by a query widget it should always be possible to specify its type. This should be specified in the DFTermExpression's options using the QUERY_TERM_TYPE constant as the key.

Specified by:

getType in class QueryFactories.QueryTermFactory

Returns:

A string that describes the type of this query term.

findPreferredWidgetType

protected QueryFactories.WidgetFactory findPreferredWidgetType(DFTermExpression qt)

Overrides:
