Methods inherited from interface Operation

clearBindings, getBindings, getDataset, getIncludeInferred, getMaxExecutionTime, removeBinding, setBinding, setDataset, setIncludeInferred, setMaxExecutionTime

Modifier and Type	Method	Description
void	clearBindings()	Removes all previously set bindings.
BindingSet	getBindings()	Retrieves the bindings that have been set on this operation.
Dataset	getDataset()	Gets the dataset that has been set using Operation.setDataset(Dataset), if any.
boolean	getIncludeInferred()	Returns whether or not this operation will return inferred statements (if any are present in the repository).
int	getMaxExecutionTime()	Returns the maximum operation execution time.
void	removeBinding(String name)	Removes a previously set binding on the supplied variable.
void	setBinding(String name, Value value)	Binds the specified variable to the supplied value.
void	setDataset(Dataset dataset)	Specifies the dataset against which to execute an operation, overriding any dataset that is specified in the operation itself.
void	setIncludeInferred(boolean includeInferred)	Determine whether evaluation results of this operation should include inferred statements (if any inferred statements are present in the repository).
void	setMaxExecutionTime(int maxExecutionTimeSeconds)	Specifies the maximum time that an operation is allowed to run.

Methods inherited from interface Query

explain, getMaxQueryTime, setMaxQueryTime

Modifier and Type	Method	Description
default Explanation	explain(Explanation.Level level)	Explain how the query will be (or has been) executed/evaluated by returning an explanation of the query plan.
int	getMaxQueryTime()	Deprecated. Use Operation.getMaxExecutionTime() instead.
void	setMaxQueryTime(int maxQueryTime)	Deprecated. Use Operation.setMaxExecutionTime(int) instead.
