All Implemented Interfaces:

Cloneable, NodeQuery, Query, Cacheable, SearchQuery, SearchQueryWrapper, PublicCloneable<Query>

public class NodeQueryWrapper
extends AbstractQueryWrapper<NodeQuery>
implements NodeQuery

Implementation of Query completely based on other instance of that.

NodeQueryWrapper

public NodeQueryWrapper(NodeQuery q)

Method Detail

getNodeStep

public Step getNodeStep()

Description copied from interface: NodeQuery

Returns the step for which the fields are added (or null)

Specified by:

getNodeStep in interface NodeQuery

Returns:

step for which the fields are added

setNodeStep

public Step setNodeStep(Step step)

Description copied from interface: NodeQuery

Removes all fields and add all fields of the given step. This also can have an effect on the result of getNodeManager().

Specified by:

setNodeStep in interface NodeQuery

Parameters:

step - add all fields of the this step

Returns:

the previously associated step (if there was one, otherwise null).

getNodeManager

public NodeManager getNodeManager()

Description copied from interface: NodeQuery

Returns the node-manager. Or 'null' if this is not yet determined.

Specified by:

getNodeManager in interface NodeQuery

Returns:

node-manager or 'null'

getStepField

public StepField getStepField(Field field)

Description copied from interface: NodeQuery

Since in a NodeQuery one of the steps is 'exceptional', also this function makes sense now.

Specified by:

getStepField in interface NodeQuery

Parameters:

field - field to get the StepField for.

Returns:

null if field is not of 'the' nodemanager.

getExtraFields

public List<StepField> getExtraFields()

Specified by:

getExtraFields in interface NodeQuery
