Constructor Detail

WriteOperations

public WriteOperations(WritableCache<R> writableCache)
                throws CacheException

Constructs for a cache.

Parameters:

writableCache - cache that contains uncommitted rows to write

Throws:

CacheException - if error

Method Detail

open

public void open()
          throws CacheException

Creates new instances of write operations and initializes them to be used by insert(Object), update(Object), delete(Object), and save(Object). Caching is turned off for write operations using SqlOperation.setCached(boolean) to avoid infinite cache recursion. Cascading is turned off for write operations with SqlOperation.setCascade(boolean) since cascades on cached tables are performed by SqlOperation.execute().

Throws:

CacheException - if error

close

public void close()
           throws CacheException

Closes write operations.

Specified by:

close in interface java.lang.AutoCloseable

Throws:

CacheException - if error

insert

public void insert(R row)
            throws CacheException

Inserts row into database with Cached.insert().

Parameters:

row - row to insert

Throws:

CacheException - if error

update

public void update(R row)
            throws CacheException

Updates row in database using primary key(s) with Cached.update().

Parameters:

row - row to update

Throws:

CacheException - if error

delete

public void delete(R row)
            throws CacheException

Deletes row from database using primary key(s) with Cached.delete().

Parameters:

row - row to delete

Throws:

CacheException - if error

save

public void save(R row)
          throws CacheException

Saves row into database using primary key(s) with Cached.save().

Parameters:

Throws:

CacheException - if error
