Constructor Detail

QueryRoot

public QueryRoot(QueryRoot queryRoot)

Deep copy constructor.

Parameters:

queryRoot -

QueryRoot

public QueryRoot(BOp[] args,
                 Map<String,Object> anns)

QueryRoot

public QueryRoot(QueryType queryType)

Method Detail

setParent

public void setParent(IGroupNode<?> parent)

This is a root node. It may not be attached as a child of another node.

Throws:

UnsupportedOperationException

getPrefixDecls

public Map<String,String> getPrefixDecls()

Description copied from interface: IPrefixDecls

The namespace prefix declarations map. This is a Map with String keys (prefix) and String values (the uri associated with that prefix).

Specified by:

getPrefixDecls in interface IPrefixDecls

Returns:

The namespace prefix declarations map. If this annotation was not set, then an empty map will be returned. The returned map is immutable to preserve the general contract for notification on mutation.

setPrefixDecls

public void setPrefixDecls(Map<String,String> prefixDecls)

Description copied from interface: IPrefixDecls

Set the namespace prefix declarations map. This is a Map with String keys (prefix) and String values (the uri associated with that prefix).

Specified by:

setPrefixDecls in interface IPrefixDecls

setDataset

public void setDataset(DatasetNode dataset)

Description copied from interface: IDataSetNode

Set the dataset.

Specified by:

setDataset in interface IDataSetNode

getDataset

public DatasetNode getDataset()

Description copied from interface: IDataSetNode

Return the dataset.

Specified by:

getDataset in interface IDataSetNode

getNamedSubqueries

public NamedSubqueriesNode getNamedSubqueries()

Return the node for the named subqueries -or- null if there it does not exist.

See Also:

getNamedSubqueriesNotNull()

getNamedSubqueriesNotNull

public NamedSubqueriesNode getNamedSubqueriesNotNull()

Return the node for the named subqueries. If the node does not exist then it is created, set on the QueryRoot and returned. This helps out with what is otherwise an awkward conditional construction pattern.

setNamedSubqueries

public void setNamedSubqueries(NamedSubqueriesNode namedSubqueries)

Set or clear the named subqueries node.

Parameters:

namedSubqueries - The named subqueries not (may be null).

See Also:

getNamedSubqueriesNotNull()

setBindingsClause

public void setBindingsClause(BindingsClause bindings)

Set the BINDINGS.

Parameters:

bindings -

getBindingsClause

public BindingsClause getBindingsClause()

Return the BINDINGS.

toString

public String toString(int indent)

Description copied from interface: IQueryNode

Pretty print with an indent.

Specified by:

toString in interface IQueryNode

Overrides:

toString in class QueryBase
