public class QuadData
extends AbstractStatementContainer<IStatementContainer>
implements IStatementContainer

Recursive container for ground StatementPatternNodes. This is used for InsertData and DeleteData. It gets flattened out and turned into an ISPO[].

Constructor Detail

QuadData

public QuadData()

QuadData

public QuadData(QuadData op)

Parameters:

op -

QuadData

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

Parameters:

args -

anns -

QuadData

public QuadData(IStatementContainer child)

Method Detail

flatten

public ConstructNode flatten(ConstructNode template)

Flatten the QuadData into a simple ConstructNode. The ConstructNode MAY use variables as well as constants and supports the context position, so this is really a quads construct template.

Parameters:

template - The ConstructNode for the template.

Returns:

The argument. TODO Maybe we could just flatten this in UpdateExprBuilder?

flatten

public JoinGroupNode flatten(JoinGroupNode container)

Flatten the StatementPatternNodes into the caller's JoinGroupNode.

Parameters:

container - The caller's container.

Returns:

The caller's container.

toString

public String toString(int indent)

Description copied from class: GroupNodeBase

Simple but robust version of to-String

Specified by:

toString in interface BOp

Specified by:

toString in interface IQueryNode

Overrides:

toString in class GroupNodeBase<IStatementContainer>

Returns:
