Constructor Detail

JdbmTable

public JdbmTable(org.apache.directory.api.ldap.model.schema.SchemaManager schemaManager,
                 String name,
                 int numDupLimit,
                 jdbm.RecordManager manager,
                 Comparator<K> keyComparator,
                 Comparator<V> valueComparator,
                 jdbm.helper.Serializer keySerializer,
                 jdbm.helper.Serializer valueSerializer)
          throws IOException

Creates a Jdbm BTree based tuple Table abstraction that enables duplicates.

Parameters:

schemaManager - The server schemaManager

name - the name of the table

numDupLimit - the size limit of duplicates before switching to BTrees for values instead of AvlTrees

manager - the record manager to be used for this table

keyComparator - a key comparator

valueComparator - a value comparator

keySerializer - a serializer to use for the keys instead of using default Java serialization which could be very expensive

valueSerializer - a serializer to use for the values instead of using default Java serialization which could be very expensive

Throws:

IOException - if the table's file cannot be created

JdbmTable

public JdbmTable(org.apache.directory.api.ldap.model.schema.SchemaManager schemaManager,
                 String name,
                 jdbm.RecordManager manager,
                 Comparator<K> keyComparator,
                 jdbm.helper.Serializer keySerializer,
                 jdbm.helper.Serializer valueSerializer)
          throws IOException

Creates a Jdbm BTree based tuple Table abstraction without duplicates enabled using a simple key comparator.

Parameters:

schemaManager - The server schemaManager

name - the name of the table

manager - the record manager to be used for this table

keyComparator - a tuple comparator

keySerializer - a serializer to use for the keys instead of using default Java serialization which could be very expensive

valueSerializer - a serializer to use for the values instead of using default Java serialization which could be very expensive

Throws:

IOException - if the table's file cannot be created
