Package org.synchronoss.cpo.cassandra.meta

Class CassandraMethodMapper

java.lang.Object

org.synchronoss.cpo.cassandra.meta.CassandraMethodMapper

All Implemented Interfaces:

Serializable, Cloneable

public class CassandraMethodMapper
extends Object
implements Serializable, Cloneable

CassandraMethodMapper defines, for each Java type CPO binds to/from Cassandra, the Row getter used to read that type back from a query result. It also serves as the registry of known driver-native Java types: org.synchronoss.cpo.cassandra.CassandraBoundStatementFactory's setBindValues consults it to tell a raw datastore-typed literal (e.g. a dynamic where-clause value) apart from a bean instance whose attribute value still needs to be extracted. There is no corresponding registry of BoundStatement setter methods -- bind values are applied via a single PreparedStatement.bind(Object...) call rather than per-attribute reflective setter invocation.
