Constructor Details

EntityHandler

protected EntityHandler(String name,
 E entity,
 EntityType<E> entityType)

entityType - the entity type

Method Details

init

protected void init()

Initializes the update query helper.

This method creates a helper with the current configuration and entity information.

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 uses the helper to determine which properties should be updated.

hasTargetPropertyTypes

protected boolean hasTargetPropertyTypes()

Returns whether this handler has target property types.

Returns:

true if this handler has target property types, false otherwise

postUpdate

protected void postUpdate()

Executes post-update entity lifecycle callbacks.

This method creates a post-update context and calls the entity type's postUpdate method.

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.

incrementVersion

protected void incrementVersion()

Increments the version property for optimistic locking.

This method increments the version property if one exists and version checking is not ignored.

populateValues

protected void populateValues(SqlContext context)

Populates values in the SQL context.

This method uses the helper to populate values for the target properties.

Parameters:

context - the SQL context
