Constructor Detail

GroupMemberNodeBase

public GroupMemberNodeBase()

GroupMemberNodeBase

public GroupMemberNodeBase(GroupMemberNodeBase<E> op)

Constructor required for com.bigdata.bop.BOpUtility#deepCopy(FilterNode).

GroupMemberNodeBase

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

Required shallow copy constructor.

Method Detail

getParent

public final IGroupNode<IGroupMemberNode> getParent()

Description copied from interface: IGroupMemberNode

Return the group to which this node belongs.

Specified by:

getParent in interface IGroupMemberNode

setParent

public final void setParent(IGroupNode<IGroupMemberNode> parent)

Description copied from interface: IGroupMemberNode

Set the group to which this bindings producer node belongs. Should only be called the group node during the addChild() method.

Specified by:

setParent in interface IGroupMemberNode

getContext

public TermNode getContext()

Description copied from interface: IGroupMemberNode

Return the context for the group graph pattern dominating this node.

Specified by:

getContext in interface IGroupMemberNode

Returns:

The context -or- null if there is no graph pattern dominating this node.

getParentJoinGroup

public JoinGroupNode getParentJoinGroup()

Description copied from interface: IGroupMemberNode

Return the lowest JoinGroupNode which dominates this node. Note that some kinds of IGroupMemberNodes do not appear within a JoinGroupNode context. For example, NamedSubqueryRoot and ConstructNode.

Specified by:

getParentJoinGroup in interface IGroupMemberNode

Returns:

The JoinGroupNode -or- null if there is no such parent join group.

getParentGraphPatternGroup

public GraphPatternGroup<IGroupMemberNode> getParentGraphPatternGroup()

Description copied from interface: IGroupMemberNode

Return the lowest GraphPatternGroup which dominates this node. Note that some kinds of IGroupMemberNodes do not appear within a GraphPatternGroup context. For example, NamedSubqueryRoot and ConstructNode.

Specified by:

getParentGraphPatternGroup in interface IGroupMemberNode

Returns:

The GraphPatternGroup -or- null if there is no such parent group.
