com.bigdata.rdf.sparql.ast.AbstractOneGraphManagement

com.bigdata.rdf.sparql.ast.DropGraph

All Implemented Interfaces:

BOp, IGroupMemberNode, IQueryNode, IVariableBindingRequirements, IPropertySet, Serializable, Cloneable

Direct Known Subclasses:

ClearGraph

public class DropGraph
extends AbstractOneGraphManagement

The DROP operation removes the specified graph(s) from the Graph Store.

 DROP  ( SILENT )? (GRAPH IRIref | DEFAULT | NAMED | ALL | GRAPHS | SOLUTIONS | SOLUTIONS %VARNAME)
 

Note: Bigdata does not support empty graphs, so DROP and CLEAR have identical semantics.
