Constructor Detail

NamedSubqueryRoot

public NamedSubqueryRoot(NamedSubqueryRoot queryBase)

Deep copy constructor.

NamedSubqueryRoot

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

Shallow copy constructor.

NamedSubqueryRoot

public NamedSubqueryRoot(QueryType queryType,
                 String name)

Parameters:

queryType -

name - The name of the subquery result set.

Method Detail

getName

public String getName()

Description copied from interface: INamedSolutionSet

Return the name of the solution set.

Specified by:

getName in interface INamedSolutionSet

Returns:

The name of the solution set.

setName

public void setName(String name)

Description copied from interface: INamedSolutionSet

Set the name of the solution set.

Specified by:

setName in interface INamedSolutionSet

Parameters:

name - The name of the solution set.

getJoinVars

public VarNode[] getJoinVars()

The join variables to be used when the named result set is included into the query.

setJoinVars

public void setJoinVars(VarNode[] joinVars)

Set the join variables.

Parameters:

joinVars - The join variables.

getDependsOn

public final String[] getDependsOn()

Return the set of named solution sets on which this named subquery depends.

Note: This is currently set by the ASTNamedSubqueryOptimizer. However, it could also be computed dynamically by scanning for NamedSubqueryIncludes within the WHERE clause of the named subquery.

NamedSubqueryRoot.Annotations.DEPENDS_ON

setDependsOn

public final void setDependsOn(String[] dependsOn)

toString

public String toString(int indent)

Description copied from class: CoreBaseBOp

The contract of this method at this level is under-specified. Sub-classes may choose between: - return a string representation of the object, similar to the use of CoreBaseBOp.toString() Or: - return a pretty-print representation of the object with indent Note that the former contract may or may not include recursive descent through a tree-like object, whereas the latter almost certainly does.

Specified by:

toString in interface BOp

Specified by:

toString in interface IQueryNode

Overrides:

toString in class QueryBase

Returns:
