Method Detail

onlyProcessesPrimaryUpdates

public boolean onlyProcessesPrimaryUpdates()

Description copied from class: UpdateProcessor

A "primary only" processor is only interested in primary updates. If a secondary update occur during the processing phase (i.e. another update to an object already processed once) then these will not be passed to a "primary only" processor.

Overrides:

onlyProcessesPrimaryUpdates in class UpdateProcessor

Returns:

true if our processor need only be passed primary updates.

processUpdate

public void processUpdate(DBObjectTransaction txn,
                          Difference objDiff)
                   throws DBException

Description copied from class: UpdateProcessor

Called by a DBObjectProvider during a create or update process. The given Difference contains new and updated objects which can be "processed" to provide their full definitions before being "saved" in the underlying database etc.

Specified by:

processUpdate in class UpdateProcessor

Parameters:

txn - the overall transaction that is being performed

objDiff - the Difference of two SystemObjects to be processed

Throws:

DBException

initialiseObject

public static final <T extends DBObject> T initialiseObject(T template)

isPendingObject

public static final boolean isPendingObject(DBObject object)

registerInitialiser

public static void registerInitialiser(TemplateExpander.Initialiser ini)

registerPropertyToClear

public static void registerPropertyToClear(java.lang.Class clearFromClass,
                                           java.lang.String clearProperty)

registerPropertiesToClear

@Deprecated

                                                         java.util.ArrayList<java.lang.String> clearPropsList,

Deprecated. Source is copied directly from the template with no modifications other than that defined by changes in the dialog.

applySourceFromTemplate

@Deprecated
public static void applySourceFromTemplate(PlSqlSourceObject template,
                                                       PlSqlSourceObject object)

Deprecated. Source is copied directly from the template with no modifications other than that defined by changes in the dialog.

getProcessorProperties

public java.util.Collection<java.lang.String> getProcessorProperties(DBObjectProvider provider)

Description copied from class: UpdateProcessor

Gets a list of the properties that exist only for this processor. If a property is used to trigger an UpdateProcessor, and that UpdateProcessor removes the property before the real update happens then it must return the property in this list so that processes outside of the provider can filter out these properties when needed.

Overrides:

getProcessorProperties in class UpdateProcessor
