                                         throws X extends Exception

Description copied from class: AbstractQueryModelNode

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 SubQueryValueOperator

Throws:

X extends Exception

replaceChildNode

public void replaceChildNode(QueryModelNode current,
                             QueryModelNode replacement)

Description copied from class: AbstractQueryModelNode

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 SubQueryValueOperator

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 SubQueryValueOperator

hashCode

public int hashCode()

Overrides:

hashCode in class SubQueryValueOperator

clone

public CompareSubQueryValueOperator 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 ValueExpr

Overrides:

clone in class SubQueryValueOperator

Returns:

A deep clone of this query model node.
