ViewImpl

public ViewImpl(Predicate predicate,
 Map<Integer, Class<? extends Term>> termConstraints,
 ViewParameters<NativeQueryType> viewParameters)

Constructs an AtomicPattern with specific constraints.

Parameters:

predicate - The predicate associated with this pattern.

termConstraints - A map associating positions (0-based index) with allowed term types.

viewParameters - the native-query parameters associated with the view

Method Details

getIndexablePatterns

public Set<Set<Integer>> getIndexablePatterns()

Description copied from interface: AtomicPattern

Returns the sets of positions that can be indexed together.

Specified by:

getIndexablePatterns in interface AtomicPattern

Returns:

An unmodifiable set of indexable position patterns.

createQueries

public Stream<BasicQuery> createQueries(Map<Integer,Term> positionsAssignation)

Description copied from interface: AtomicPattern

Creates basic queries compatible with this atom.

The result can be empty if it is not possible to build a Basic Query

Specified by:

createQueries in interface AtomicPattern

Parameters:

positionsAssignation - the assignation of the positions

Returns:

A stream containing the BasicQueries compatible with this termSequence.

getViewParameters

public ViewParameters<NativeQueryType> getViewParameters()

Description copied from interface: View

Returns the parameters used to query the underlying native view.

Specified by:

getViewParameters in interface View<NativeQueryType>

Returns:

the view parameters
