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).
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.

Method Detail

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.

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().

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).

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().

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).

Returns:

toString

public String toString()
