visit

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

Description copied from interface: QueryModelNode

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

Throws:

X extends Exception

visitChildren

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

Description copied from class: QueryModelNodeBase

Dummy implementation of QueryModelNode.visitChildren(org.openrdf.query.algebra.QueryModelVisitor<X>) that does nothing. Subclasses should override this method when they have child nodes.

Specified by:

visitChildren in interface QueryModelNode

Overrides:

visitChildren in class QueryModelNodeBase

Throws:

X extends Exception

replaceChildNode

public void replaceChildNode(QueryModelNode current,
                             QueryModelNode replacement)

Description copied from class: QueryModelNodeBase

Default implementation of QueryModelNode.replaceChildNode(QueryModelNode, QueryModelNode) that throws an IllegalArgumentException indicating that current is not a child node of this node.

Specified by:

replaceChildNode in interface QueryModelNode

Overrides:

replaceChildNode in class QueryModelNodeBase

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 ProjectionElemList 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

Overrides:

clone in class QueryModelNodeBase

Returns:

A deep clone of this query model node.
