Method Details

getBindingRepresentation

public String getBindingRepresentation()

getNamedQueryParams

Returns:

Map containing Named Query parameter name/value pairs

getInteractions

public InteractionDescriptor[] getInteractions()

startup

public void startup(CommonContext context)

Tells tag listeners to subscribe

shutdown

public void shutdown()

Tells tag listeners to unsubscribe

getListener

public PropertyChangeListener getListener()

setListener

public void setListener(PropertyChangeListener listener)

childInteractionUpdated

public void childInteractionUpdated()

Specified by:

childInteractionUpdated in interface InteractionListener

getNodes

public QueryHolder.QueryNode[] getNodes()

getQuery

public String getQuery()

setNodes

public void setNodes(QueryHolder.QueryNode[] nodes)

setDynamicNamedQueryParams

public void setDynamicNamedQueryParams(QueryHolder.NamedQueryNode[] dynamicNamedQueryParams)

setStaticNamedQueryParams

public void setStaticNamedQueryParams(Map<String,Object> staticNamedQueryParams)
