Constructor Summary

SelectProjection()

Method Summary

SelectProjection	clone() Returns a (deep) clone of this query model node.
boolean	equals(Object obj) Returns true if this query model node and its children are recursively equal to o and its children.
SqlExpr	getDatatype()
RefIdColumn	getId()
SqlExpr	getLanguage()
SqlExpr	getStringValue()
ColumnVar	getVar()
int	hashCode()
void	replaceChildNode(QueryModelNode current, QueryModelNode replacement) Default implementation of QueryModelNode.replaceChildNode(QueryModelNode, QueryModelNode) that throws an IllegalArgumentException indicating that current is not a child node of this node.
void	setDatatype(SqlExpr datatype)
void	setId(RefIdColumn id)
void	setLanguage(SqlExpr language)
void	setStringValue(SqlExpr stringValue)
void	setVar(ColumnVar var)
<X extends Exception> void	visit(RdbmsQueryModelVisitorBase<X> visitor)
<X extends Exception> void	visitChildren(QueryModelVisitor<X> visitor) Dummy implementation of QueryModelNode.visitChildren(org.openrdf.query.algebra.QueryModelVisitor) that does nothing.

           throws X extends Exception

Specified by:

visit in class RdbmsQueryModelNodeBase

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) 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.

clone

public SelectProjection 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.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

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
