public class BooleanParameter

extends Parameter

A Parameter that specifies a boolean value that you use in creating a query. After creating the query, you can change the value of the BooleanParameter and thereby change the selection of dimension or measure elements that the query represents.

You use a BooleanParameter to create a parameterized BooleanSource with the createParameterizedSource(BooleanParameter param) method of the DataProvider you used to create the BooleanParameter. You then use the parameterized BooleanSource as a parameter to a method that selects one or more elements of another Source and produces a derived Source. You can commit the Transaction and create a Cursor for the Source to retrieve the results of the query.

You can change the selection of elements that the derived Source represents by changing the value of the BooleanParameter with one of its setValue methods. The Cursor for the query Source then has the values of the new selection. You do not need to commit the Transaction nor create a new Cursor. You can instead just set the position of the existing Cursor to its first position and get the values for the new selection from the Cursor.
