Member Function Documentation

asResource()

ResourcePtr Syndication::RDF::Statement::asResource ( ) const

virtual

returns the object of this statement as resource, if possible.

Returns

the object node as Resource, or null if the object is not a resource

Definition at line 101 of file statement.cpp.

asString()

QString Syndication::RDF::Statement::asString ( ) const

virtual

returns the object of this statement as string, if possible.

Returns

the literal text as QString, or a null string if the object is not a literal

Definition at line 112 of file statement.cpp.

isNull()

bool Syndication::RDF::Statement::isNull ( ) const

virtual

returns whether this statement is a null statement (i.e.

was created using Statement())

Definition at line 78 of file statement.cpp.

object()

NodePtr Syndication::RDF::Statement::object ( ) const

virtual

the object of the statement

Definition at line 95 of file statement.cpp.

operator=()

Statement & Syndication::RDF::Statement::operator=

(

const Statement &

other

)

assigns another statement

Parameters

other

the statement to assign

Definition at line 63 of file statement.cpp.

operator==()

bool Syndication::RDF::Statement::operator== ( const Statement & other ) const

virtual

returns whether two statements are equal.

Currently statements are equal, if they are from the same model (!) and subject, predicate and object are equal.

Parameters

other

the statement to compare to

Definition at line 69 of file statement.cpp.

virtual

the subject of the statement.
