Method Detail

getParent

IGroupNode<IGroupMemberNode> getParent()

Return the group to which this node belongs.

setParent

void setParent(IGroupNode<IGroupMemberNode> parent)

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

getParentJoinGroup

JoinGroupNode getParentJoinGroup()

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.

Returns:

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

getParentGraphPatternGroup

GraphPatternGroup<IGroupMemberNode> getParentGraphPatternGroup()

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.

Returns:

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

getContext

TermNode getContext()

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

Returns:

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