Member Function Documentation

QStringList Soprano::BindingSet::bindingNames

(

)

const

Returns:

The names of the bound variables in this set.

bool Soprano::BindingSet::contains

(

const QString &

name

)

const

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 Soprano::BindingSet::count

(

)

const

The number of bindings in this set.

Returns:

The number of bindings.

void Soprano::BindingSet::insert	(	const QString &	name,
		const Node &	value
	)

Insert a new binding into the set.

BindingSet& Soprano::BindingSet::operator=

(

const BindingSet &

)

Node Soprano::BindingSet::operator[]

(

const QString

name

)

const

Get the binding for a variable.

This is equivalent to value(const QString&) const.

Node Soprano::BindingSet::operator[]

(

int

offset

)

const

Get the binding for a variable by index.

This is equivalent to value(int) const.

void Soprano::BindingSet::replace	(	const QString &	name,
		const Node &	value
	)

Replaces a value in the binding set.

Since:

2.3

void Soprano::BindingSet::replace	(	int	offset,
		const Node &	value
	)

Replaces a value in the binding set.

Since:

2.3

Node Soprano::BindingSet::value

(

const QString &

name

)

const

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.

See also:

QueryResultIterator::binding(const QString&) const.

Node Soprano::BindingSet::value

(

int

offset

)

const

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().

QueryResultIterator::binding(int) const.
