Method Detail

openSession

void openSession()

Callback about a session being opened.

closeSession

void closeSession()

Callback about a session being closed.

flush

void flush()

Callback about a flush occurring

connect

void connect()

Callback about a connection being obtained from ConnectionProvider

prepareStatement

void prepareStatement()

Callback about a statement being prepared.

closeStatement

void closeStatement()

Callback about a statement being closed.

endTransaction

void endTransaction(boolean success)

Callback about a transaction completing.

Parameters:

success - Was the transaction successful?

loadEntity

void loadEntity(String entityName)

Callback about an entity being loaded. This might indicate a proxy or a fully initialized entity, but in either case it means without a separate SQL query being needed.

Parameters:

entityName - The name of the entity loaded.

fetchEntity

void fetchEntity(String entityName)

Callback about an entity being fetched. Unlike loadEntity(java.lang.String) this indicates a separate query being performed.

Parameters:

entityName - The name of the entity fetched.

updateEntity

void updateEntity(String entityName)

Callback about an entity being updated.

Parameters:

entityName - The name of the entity updated.

insertEntity

void insertEntity(String entityName)

Callback about an entity being inserted

Parameters:

entityName - The name of the entity inserted

deleteEntity

void deleteEntity(String entityName)

Callback about an entity being deleted.

Parameters:

entityName - The name of the entity deleted.

optimisticFailure

void optimisticFailure(String entityName)

Callback about an optimistic lock failure on an entity

Parameters:

entityName - The name of the entity.

loadCollection

void loadCollection(String role)

Callback about a collection loading. This might indicate a lazy collection or an initialized collection being created, but in either case it means without a separate SQL query being needed.

Parameters:

role - The collection role.

fetchCollection

void fetchCollection(String role)

Callback to indicate a collection being fetched. Unlike loadCollection(java.lang.String), this indicates a separate query was needed.

Parameters:

role - The collection role.

updateCollection

void updateCollection(String role)

Callback indicating a collection was updated.

Parameters:

role - The collection role.

Callback indicating a collection recreation (full deletion + full (re-)insertion).

Parameters:

role - The collection role.

removeCollection

void removeCollection(String role)

Callback indicating a collection removal.

Parameters:

role - The collection role.
