Method Documentation
| __init__ | ( | self ) |
Create an emtpy set.
| __init__ | ( | self, | ||
| Soprano.BindingSet | other | |||
| ) |
Copy constructor.
| QStringList bindingNames | ( | self ) |
- Returns:
- The names of the bound variables in this set.
| bool contains | ( | self, | ||
| QString | name | |||
| ) |
Check if a certain variable has a binding in this set.
- Parameters:
-
name The variable name.
- Returns:
- true if this set contains a binding for the variable name, false otherwise.
| int count | ( | self ) |
The number of bindings in this set.
- Returns:
- The number of bindings.
| insert | ( | self, | ||
| QString | name, | |||
| Soprano.Node | value | |||
| ) |
Insert a new binding into the set.
| Soprano.Node operator [] | ( | self, | ||
| int | offset | |||
| ) |
Get the binding for a variable by index.
This is equivalent to value(int) const.
| Soprano.Node operator [] | ( | self, | ||
| QString | name | |||
| ) |
Get the binding for a variable.
This is equivalent to value(const QString&) const.
| replace | ( | self, | ||
| int | offset, | |||
| Soprano.Node | value | |||
| ) |
Replaces a value in the binding set.
- Since:
- 2.3
| replace | ( | self, | ||
| QString | name, | |||
| Soprano.Node | value | |||
| ) |
Replaces a value in the binding set.
- Since:
- 2.3
| Soprano.Node value | ( | self, | ||
| int | offset | |||
| ) |
Get the binding for a variable by index.
- Parameters:
-
offset The index of the requested variable.
- Returns:
- The binding for the requested variable or and invalid node if offset is out of bounds, i.e. bigger or equal to count().
\sa QueryResultIterator.binding(int) const.
| Soprano.Node value | ( | self, | ||
| QString | name | |||
| ) |
Get the binding for a variable.
- Parameters:
-
name The name of the requested variable.
- Returns:
- The binding for the requested variable or and invalid node if the bindings do not contain the variable.
\sa QueryResultIterator.binding(const QString&) const.
