public class DeleteInsertGraph
extends GraphUpdate
implements IGraphPatternContainer, IDataSetNode

The DELETE/INSERT operation can be used to remove or add triples from/to the Graph Store based on bindings for a query pattern specified in a WHERE clause:

 ( WITH IRIref )?
 ( ( DeleteClause InsertClause? ) | InsertClause )
 ( USING ( NAMED )? IRIref )*
 WHERE GroupGraphPattern
 

The DeleteClause and InsertClause forms can be broken down as follows:

 DeleteClause ::= DELETE  QuadPattern 
 InsertClause ::= INSERT  QuadPattern

Method Detail

setDataset

public void setDataset(DatasetNode dataset)

Set the dataset.

Note: The data set can only be specified for the general case of DELETE/INSERT. The data set is specific to the DELETE/INSERT operation to which it is attached (it is not inherited or combined with the data set for later operations in a sequence).

Specified by:

setDataset in interface IDataSetNode

getDataset

public DatasetNode getDataset()

Description copied from interface: IDataSetNode

Return the dataset.

Specified by:

getDataset in interface IDataSetNode

getWhereClause

public GraphPatternGroup getWhereClause()

Return the GraphPatternGroup for the WHERE clause.

Returns:

The WHERE clause -or- null.

getGraphPattern

public GraphPatternGroup<IGroupMemberNode> getGraphPattern()

Description copied from interface: IGraphPatternContainer

Return the graph pattern.

Specified by:

getGraphPattern in interface IGraphPatternContainer

setWhereClause

public void setWhereClause(GraphPatternGroup<IGroupMemberNode> whereClause)

Set the WHERE clause.

setGraphPattern

public void setGraphPattern(GraphPatternGroup<IGroupMemberNode> graphPattern)

Description copied from interface: IGraphPatternContainer

Set the graph pattern.

Specified by:

setGraphPattern in interface IGraphPatternContainer

getDeleteClause

public QuadsDataOrNamedSolutionSet getDeleteClause()

Return the template for the DELETE clause.

getInsertClause

public QuadsDataOrNamedSolutionSet getInsertClause()

Return the template for the INSERT clause.

setDeleteClause

public void setDeleteClause(QuadsDataOrNamedSolutionSet data)

setInsertClause

public void setInsertClause(QuadsDataOrNamedSolutionSet data)

toString

public final String toString(int indent)

Description copied from class: CoreBaseBOp

The contract of this method at this level is under-specified. Sub-classes may choose between: - return a string representation of the object, similar to the use of CoreBaseBOp.toString() Or: - return a pretty-print representation of the object with indent Note that the former contract may or may not include recursive descent through a tree-like object, whereas the latter almost certainly does.

Specified by:

toString in interface BOp

Specified by:

toString in interface IQueryNode

Overrides:

toString in class CoreBaseBOp

Returns:
