Member Function Documentation
| ResourcePtr Syndication::RDF::Statement::asResource | ( | ) | const [virtual] |
returns the object of this statement as resource, if possible.
- Returns:
- the object node as Resource, or
nullif the object is not a resource
Definition at line 119 of file statement.cpp.
| 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 129 of file statement.cpp.
| bool Syndication::RDF::Statement::isNull | ( | ) | const [virtual] |
returns whether this statement is a null statement (i.e.
was created using Statement())
Definition at line 96 of file statement.cpp.
| NodePtr Syndication::RDF::Statement::object | ( | ) | const [virtual] |
the object of the statement
Definition at line 113 of file statement.cpp.
assigns another statement
- Parameters:
-
other the statement to assign
Definition at line 82 of file statement.cpp.
| 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 88 of file statement.cpp.
| PropertyPtr Syndication::RDF::Statement::predicate | ( | ) | const [virtual] |
the predicate of the statement
Definition at line 107 of file statement.cpp.
| ResourcePtr Syndication::RDF::Statement::subject | ( | ) | const [virtual] |
the subject of the statement.
