Interface BGP

All Superinterfaces:

Query, SPARQLGraphPattern

All Known Implementing Classes:

BGPImpl, StarPattern

public interface BGP
extends SPARQLGraphPattern

This interface represents basic graph patterns (BGPs).

Method Summary

Modifier and Type	Method	Description
BGP	applySolMapToGraphPattern(SolutionMapping sm)	Applies the given solution mapping to this graph pattern and returns the resulting graph pattern in which all occurrences of the variables bound by the given solution mapping are replaced by the RDF terms that the solution mappings assigns to these variables.
Set<TriplePattern>	getTriplePatterns()	Returns an unmodifiable set of triple patterns.
BGP	mergeWith(BGP otherBGP)	Return a BGP that contains all triple patterns of this BGP plus all triple patterns of the given BGP.
BGP	mergeWith(TriplePattern tp)	Returns a BGP that contains all triple patterns of this BGP plus the given triple pattern.
String	toString()	Returns a string representation of the BGP

Method Details

getTriplePatterns

Set<TriplePattern> getTriplePatterns()

Returns an unmodifiable set of triple patterns.

toString

String toString()

Returns a string representation of the BGP

Overrides:

toString in class Object

applySolMapToGraphPattern

BGP applySolMapToGraphPattern(SolutionMapping sm)
                       throws VariableByBlankNodeSubstitutionException

Description copied from interface: SPARQLGraphPattern

Applies the given solution mapping to this graph pattern and returns the resulting graph pattern in which all occurrences of the variables bound by the given solution mapping are replaced by the RDF terms that the solution mappings assigns to these variables.

Specified by:

applySolMapToGraphPattern in interface SPARQLGraphPattern

Throws:

VariableByBlankNodeSubstitutionException - if one of the variables would be replaced by a blank node

mergeWith

BGP mergeWith(TriplePattern tp)

Returns a BGP that contains all triple patterns of this BGP plus the given triple pattern. This method is a more specific version of SPARQLGraphPattern.mergeWith(SPARQLGraphPattern).

mergeWith

BGP mergeWith(BGP otherBGP)

Return a BGP that contains all triple patterns of this BGP plus all triple patterns of the given BGP. This method is a more specific version of SPARQLGraphPattern.mergeWith(SPARQLGraphPattern).
