Method Details

visit

public <X extends Exception> void visit(QueryModelVisitor<X> visitor)
                                 throws X

Description copied from interface: QueryModelNode

Visits this node. The node reports itself to the visitor with the proper runtime type.

Specified by:

visit in interface QueryModelNode

Throws:

X

visitChildren

public <X extends Exception> void visitChildren(QueryModelVisitor<X> visitor)
                                         throws X

Description copied from interface: QueryModelNode

Visits the children of this node. The node calls QueryModelNode.visit(QueryModelVisitor) on all of its child nodes.

Specified by:

visitChildren in interface QueryModelNode

Throws:

X

replaceChildNode

public void replaceChildNode(QueryModelNode current,
 QueryModelNode replacement)

Description copied from interface: QueryModelNode

Replaces one of the child nodes with a new node.

Specified by:

replaceChildNode in interface QueryModelNode

Parameters:

current - The current child node.

replacement - The new child node.

equals

public boolean equals(Object other)

Description copied from interface: QueryModelNode

Returns true if this query model node and its children are recursively equal to o and its children.

Specified by:

equals in interface QueryModelNode

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

clone

public Copy clone()

Description copied from interface: QueryModelNode

Returns a (deep) clone of this query model node. This method recursively clones the entire node tree, starting from this nodes.

Specified by:

clone in interface QueryModelNode

Specified by:

clone in interface UpdateExpr

Overrides:

clone in class AbstractQueryModelNode

Returns:

A deep clone of this query model node.

setSourceGraph

public void setSourceGraph(ValueConstant graph)

Parameters:

graph - The graph to set.

getSourceGraph

public ValueConstant getSourceGraph()

The named graph from which to copy. If null, the default graph should be used.

Returns:

Returns the graph.

setSilent

public void setSilent(boolean silent)

Parameters:

silent - The silent to set.

isSilent

public boolean isSilent()

Specified by:

isSilent in interface UpdateExpr

Returns:

Returns the silent.

setDestinationGraph

public void setDestinationGraph(ValueConstant destinationGraph)

Parameters:

destinationGraph - The destinationGraph to set.

getDestinationGraph

public ValueConstant getDestinationGraph()

The named graph to which to copy. If null, the default graph should be used.

Returns:

Returns the destinationGraph.
