Method Detail

createCacheFlushHints

protected void createCacheFlushHints()

Description copied from class: AbstractNodeAction

This template method is called when the node to edit is changed. custom cachflush hints can be set here. This class dous not know if the current node is updated or created, so it dousn't know what kind of events to create.

Specified by:

createCacheFlushHints in class AbstractNodeAction

createRelation

protected Node createRelation(Transaction transaction,
                              Map<String,Node> idMap,
                              HttpServletRequest request)

Description copied from class: AbstractRelationAction

This template method should be implemented by concrete implementations of this class. It is called by AbstractRelationAction.createNode(Transaction, Map, HttpServletRequest) after all the preliminary checks.

Specified by:

createRelation in class AbstractRelationAction

Returns:

processNode

protected void processNode(Transaction transaction)

When sortField is set, and it is a valid field, the sort position is calculated and set on the new relation.

Overrides:

processNode in class AbstractNodeAction

See Also:

AbstractNodeAction.processNode(org.mmbase.bridge.Transaction)

resolvePosition

protected final Integer resolvePosition(Transaction transaction)

Derive the position field value, if sortField is set. If something goes wrong a global error is set. The sort position value will be, depending on the sortPostion field, either the lowest current sort position value minus 1, or the highest current sort position value plus one.

Parameters:

transaction -

Returns:

the value to be inserted as the new sort position.

getSortPosition

public String getSortPosition()

setSortPosition

public void setSortPosition(String sortPosition)

getSortField

public String getSortField()

setSortField

public void setSortField(String sortField)

setRole

public void setRole(String role)

Overrides:

setRole in class AbstractRelationAction
