- metadata
- MetadataWorkspace
The metadata workspace that the command tree should use.
- dataSpace
- DataSpace
The logical 'space' that metadata in the expressions used in this command tree must belong to.
- query
- DbExpression
A DbExpression that defines the logic of the query.
Exceptions

or
query
is null
dataSpace
does not represent a valid data space
