Class WrappingSolutionMappingsIndex

java.lang.Object

se.liu.ida.hefquin.base.datastructures.impl.WrappingSolutionMappingsIndex

All Implemented Interfaces:

Iterable<SolutionMapping>, Collection<SolutionMapping>, SolutionMappingsIndex, StatsProvider

Direct Known Subclasses:

SolutionMappingsIndexForMixedUsage, SolutionMappingsIndexWithPostMatching

public class WrappingSolutionMappingsIndex
extends Object
implements SolutionMappingsIndex

Base class for implementations of SolutionMappingsIndex that wrap another SolutionMappingsIndex. This base class simply forwards all method calls to the wrapped index. Subclasses may override this behavior for selected methods.

getJoinPartners

public Iterable<SolutionMapping> getJoinPartners(SolutionMapping sm)
                                          throws UnsupportedOperationException

Description copied from interface: SolutionMappingsIndex

Returns an iterator over all solution mappings in this index that are compatible with the given solution mappings. Implementations may choose to support this method only for specific types of solution mappings (e.g., with specific variables), in which case an UnsupportedOperationException will be thrown if the method is called with an unsupported variable.

Specified by:

getJoinPartners in interface SolutionMappingsIndex

Throws:

UnsupportedOperationException

findSolutionMappings

public Iterable<SolutionMapping> findSolutionMappings(org.apache.jena.sparql.core.Var var,
 org.apache.jena.graph.Node value)
                                               throws UnsupportedOperationException

Description copied from interface: SolutionMappingsIndex

Returns an iterator over all solution mappings in this index that map the given variable to the given value. Implementations may choose to support this method only for specific variables, in which case an UnsupportedOperationException will be thrown if the method is called with an unsupported variable. The result of this method should essentially be the same as the result of calling SolutionMappingsIndex.getJoinPartners(SolutionMapping) with a solution mapping that is defined only for the given variable and that maps this variable to the given value.

Specified by:

findSolutionMappings in interface SolutionMappingsIndex

Throws:

UnsupportedOperationException

findSolutionMappings

public Iterable<SolutionMapping> findSolutionMappings(org.apache.jena.sparql.core.Var var1,
 org.apache.jena.graph.Node value1,
 org.apache.jena.sparql.core.Var var2,
 org.apache.jena.graph.Node value2)
                                               throws UnsupportedOperationException

Description copied from interface: SolutionMappingsIndex

Returns an iterator over all solution mappings in this index that map the first variable to the first value and the second variable to the second value. Hence, this method is a two-variables version of the method SolutionMappingsIndex.findSolutionMappings(Var, Node).

Specified by:

findSolutionMappings in interface SolutionMappingsIndex

Throws:

UnsupportedOperationException

findSolutionMappings

public Iterable<SolutionMapping> findSolutionMappings(org.apache.jena.sparql.core.Var var1,
 org.apache.jena.graph.Node value1,
 org.apache.jena.sparql.core.Var var2,
 org.apache.jena.graph.Node value2,
 org.apache.jena.sparql.core.Var var3,
 org.apache.jena.graph.Node value3)
                                               throws UnsupportedOperationException

Description copied from interface: SolutionMappingsIndex

This method is a three-variables version of the method SolutionMappingsIndex.findSolutionMappings(Var, Node).

Specified by:

findSolutionMappings in interface SolutionMappingsIndex

Throws:

UnsupportedOperationException

getAllSolutionMappings

public Iterable<SolutionMapping> getAllSolutionMappings()

Description copied from interface: SolutionMappingsIndex

Returns all solution mappings currently in this index.

Specified by:

getAllSolutionMappings in interface SolutionMappingsIndex
