Method Summary

Modifier and Type	Method and Description
AVT	asAnonymousVariable() Returns a representation of this element as a blank node (assuming it is a specific, but non-named variable).
CTT	asConstantTerm() Returns a representation of this element as a constant RDF term (i.e., a URI or a literal).
NVT	asNamedVariable() Returns a representation of this element as a named variable (assuming it is a specific variable that has a name).
boolean	isAnonymousVariable() Returns true if this element is a specific variable that does not have a name (i.e., it is denoted by a blank node), and false if either it is not a specific variable or it is a specific variable that has a name.
boolean	isNamedVariable() Returns true if this element is a specific variable that has a name (i.e., it is denoted by a string that begins with a question mark), and false if either it is not a specific variable or it is a specific variable that is denoted by a blank node.
boolean	isSpecificVariable() Returns true if this element is a specific variable, and false if either it is not a variable (but a URI or literal) or it is some variable that is not specified.
boolean	isVariable() Returns true if this element is a variable (specific or unspecified).

Method Detail

isVariable

public boolean isVariable()

Description copied from interface: ITriplePatternElement

Returns true if this element is a variable (specific or unspecified).

Specified by:

isVariable in interface ITriplePatternElement<CTT,NVT,AVT>

Returns:

isSpecificVariable

public boolean isSpecificVariable()

Description copied from interface: ITriplePatternElement

Returns true if this element is a specific variable, and false if either it is not a variable (but a URI or literal) or it is some variable that is not specified. The latter (unspecified variables) is possible because when a client requests a triple pattern fragment, it may omit triple pattern related parameters.

Specified by:

isSpecificVariable in interface ITriplePatternElement<CTT,NVT,AVT>

Returns:

isNamedVariable

public boolean isNamedVariable()

Description copied from interface: ITriplePatternElement

Returns true if this element is a specific variable that has a name (i.e., it is denoted by a string that begins with a question mark), and false if either it is not a specific variable or it is a specific variable that is denoted by a blank node. If this element is a specific variable that has a name (that is, this method returns true), the named variable can be obtained by the method ITriplePatternElement.asNamedVariable().

Specified by:

isNamedVariable in interface ITriplePatternElement<CTT,NVT,AVT>

Returns:

asNamedVariable

public NVT asNamedVariable()

Description copied from interface: ITriplePatternElement

Returns a representation of this element as a named variable (assuming it is a specific variable that has a name).

Specified by:

asNamedVariable in interface ITriplePatternElement<CTT,NVT,AVT>

Returns:

isAnonymousVariable

public boolean isAnonymousVariable()

Description copied from interface: ITriplePatternElement

Returns true if this element is a specific variable that does not have a name (i.e., it is denoted by a blank node), and false if either it is not a specific variable or it is a specific variable that has a name. If this element is a specific variable denoted by a blank node (that is, this method returns true), the blank node can be obtained by the method ITriplePatternElement.asAnonymousVariable().

Specified by:

isAnonymousVariable in interface ITriplePatternElement<CTT,NVT,AVT>

Returns:

asAnonymousVariable

public AVT asAnonymousVariable()

Description copied from interface: ITriplePatternElement

Returns a representation of this element as a blank node (assuming it is a specific, but non-named variable).

Specified by:

asAnonymousVariable in interface ITriplePatternElement<CTT,NVT,AVT>

Returns:

asConstantTerm

public CTT asConstantTerm()

Description copied from interface: ITriplePatternElement

Returns a representation of this element as a constant RDF term (i.e., a URI or a literal).

Specified by:

asConstantTerm in interface ITriplePatternElement<CTT,NVT,AVT>

Returns:

toString

public String toString()

Overrides:

toString in class Object
