Method Details

init

protected void init()

Initializes this handler.

This method creates a batch update query helper with the configured properties.

preUpdate

protected void preUpdate()

Executes pre-update entity lifecycle callbacks.

This method creates a pre-update context and calls the entity type's preUpdate method.

prepareTargetPropertyTypes

protected void prepareTargetPropertyTypes()

Prepares the target property types for this query.

This method retrieves the target property types from the helper.

postUpdate

protected void postUpdate()

Executes post-update entity lifecycle callbacks.

This method creates a post-update context, calls the entity type's postUpdate method, and saves the current state of the entity.

prepareOptimisticLock

protected void prepareOptimisticLock()

Prepares optimistic locking for this query.

This method sets the optimistic lock check flag based on the version property and configuration.

incrementVersions

protected void incrementVersions()

Increments version values for optimistic locking.

This method increments the version property value for each entity in the batch if optimistic locking is enabled.

populateValues

protected void populateValues(SqlContext context)

Populates values in the SQL context.

This method delegates to the helper to populate values for the current entity.

Parameters:

context - the SQL context
