public class LoadGraph
extends GraphUpdate

The LOAD operation reads an RDF document from a IRI and inserts its triples into the specified graph in the Graph Store.

 LOAD ( SILENT )? IRIref_from ( INTO GRAPH IRIref_to )?

Method Detail

getSourceGraph

public ConstantNode getSourceGraph()

The ConstantNode for the source graph (for operations which have this concept).

Note: For LoadGraph, this is the URI of the external resource to be loaded.

Overrides:

getSourceGraph in class Update

setSourceGraph

public void setSourceGraph(ConstantNode sourceGraph)

Overrides:

setSourceGraph in class Update

getTargetGraph

public ConstantNode getTargetGraph()

Description copied from class: Update

The ConstantNode for the target graph (for operations which have this concept). If there is only one graph on which the operation will have an effect, then it is modeled by this annotation.

Overrides:

getTargetGraph in class Update

setTargetGraph

public void setTargetGraph(ConstantNode targetGraph)

Overrides:

setTargetGraph in class Update

isSilent

public boolean isSilent()

Description copied from class: Update

The "SILENT" option (default false) (for operations which have this concept).

Overrides:

isSilent in class Update

setSilent

public void setSilent(boolean silent)

Overrides:

setSilent in class Update

toString

public 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:
