Method Detail

save

public <T> void save(Class<T> klazz,
                     T t)

Upserts a record to the database. There is no validation of previously existing

Type Parameters:

T -

Parameters:

klazz -

t -

count

public Long count(Class<?> klazz)

Gets the count of a given table. Not on v1 protocol servers such as pre Cassandra 2.0 the default limit of 5k will be in place. For 2.0 and later paging will take over on larger queries and there should be no limit.

Parameters:

klazz - class needed for interrogation of @Table annotation and it depends on the optional keyspace parameter being set today

Returns:

Total count of the table

markForCleanUp

public void markForCleanUp(Class<?> klazz)

simple method to make a table for cleanup in case you've not managed to visit it by other means. This should not be the preferred method of marking for cleanup, and one should rely on the get, delete, and save functions.

Parameters:

klazz - must have @Table annotation from datastax mapping project

get

public <T> T get(Class<T> klazz,
                 Object... keys)

Gets a record by full primary key and marks the table for cleanup later.

Type Parameters:

T - Must be a class with the DataStax Java Driver @Table annotation

Parameters:

klazz -

keys - must contain all objects that make up the primary key

Returns:

returns a single instance of the specified class from Cassandra

delete

public <T> void delete(Class<T> klazz,
                       Object... keys)

Deletes a record. Does not handle cleanup

Type Parameters:

T - Must be a class with the DataStax Java Driver @Table annotation

Parameters:

klazz -

keys - must contain all objects that make up the primary key
