Class JDBCHashMap<K,V>

AbstractJDBCHashMap

net.corda.node.utilities.JDBCHashMap<K,V>

public class JDBCHashMap<K,V>
extends AbstractJDBCHashMap

A convenient JDBC table backed hash map with iteration order based on insertion order. See class AbstractJDBCHashMap for further implementation details.

In this subclass, keys and values are represented by Blobs of Kryo serialized forms of the key and value objects. If you can extend class AbstractJDBCHashMap and implement less Kryo dependent key and/or value mappings then that is likely preferrable.

Method Detail

keyFromRow

public K keyFromRow(org.jetbrains.exposed.sql.ResultRow row)

Implementation should return the key object marshalled from the database table row.

See example implementations in class JDBCHashMap.

class JDBCHashMap

valueFromRow

public V valueFromRow(org.jetbrains.exposed.sql.ResultRow row)

Implementation should return the value object marshalled from the database table row.

See example implementations in class JDBCHashMap.

class JDBCHashMap

addKeyToInsert

public void addKeyToInsert(org.jetbrains.exposed.sql.statements.InsertStatement insert,
                           java.util.Map.Entry<? extends K,? extends V> entry,
                           java.util.List<kotlin.jvm.functions.Function0> finalizables)

Implementation should marshall the key to the insert statement.

If some cleanup is required after the insert statement is executed, such as closing a Blob, then add a closure to the finalizables to do so.

See example implementations in class JDBCHashMap.

addValueToInsert

public void addValueToInsert(org.jetbrains.exposed.sql.statements.InsertStatement insert,
                             java.util.Map.Entry<? extends K,? extends V> entry,
                             java.util.List<kotlin.jvm.functions.Function0> finalizables)

Implementation should marshall the value to the insert statement.

If some cleanup is required after the insert statement is executed, such as closing a Blob, then add a closure to the finalizables to do so.

See example implementations in class JDBCHashMap.
