H2ChildMap

public H2ChildMap(java.lang.Object fkId)

Create a new map and associate it with the specified key in the main table.

Parameters:

fkId - The foreign key ID from the main table.

Method Detail

persist

public void persist()

Persist this collection to database.

This is a no-op, as the main table will take care of persisting the values, in a single batch insert.

Specified by:

persist in interface StoredCollection

Overrides:

persist in class H2Map

persistChanges

void persistChanges(java.sql.PreparedStatement ps)
             throws java.sql.SQLException

Persist the changes for this child map, using the specified insert statement.

Parameters:

ps - The insert statement.

Throws:

java.sql.SQLException - For SQL-related errors when setting the statement arguments.

putSuper

void putSuper(java.lang.Object key,
              java.lang.Object value)

Perform a put operation in this map, avoiding logging this change.

Parameters:

key - The map key.

value - The map value.

logChange

void logChange(long fileId,
               long astId,
               java.lang.Object key,
               java.lang.Object value)

Log this change being made to the collection.

Parameters:

fileId - The AST file ID.

astId - The source AST ID.

key - The collection key.

value - The value, which is non-null only for maps.
