Modifier and Type | Method and Description |
---|---|
void |
close()
Closes the underlying Db of this Table.
|
long |
count(K key)
Gets the count of the number of records in this Table with a specific
key: returns the number of duplicates for a key.
|
org.apache.directory.api.ldap.model.cursor.Cursor<org.apache.directory.api.ldap.model.cursor.Tuple<K,V>> |
cursor()
Creates a Cursor that traverses Tuples in a Table.
|
org.apache.directory.api.ldap.model.cursor.Cursor<org.apache.directory.api.ldap.model.cursor.Tuple<K,V>> |
cursor(K key)
Creates a Cursor that traverses Table Tuples for the same key.
|
V |
get(K key)
Gets the value of a record by key if the key exists.
|
long |
greaterThanCount(K key)
Gets the number of records greater than or equal to a key value.
|
boolean |
has(K key)
Checks to see if this table has one or more tuples with a specific key:
this is exactly the same as a get call with a check to see if the
returned value is null or not.
|
boolean |
has(K key,
V value)
Checks to see if this table has a key with a specific value.
|
boolean |
hasGreaterOrEqual(K key)
Checks to see if this table has a record with a key greater than or
equal to the key argument.
|
boolean |
hasGreaterOrEqual(K key,
V val)
Checks to see if this table has a Tuple with a key equal to the key
argument, yet with a value greater than or equal to the value argument
provided.
|
boolean |
hasLessOrEqual(K key)
Checks to see if this table has a record with a key less than or
equal to the key argument.
|
boolean |
hasLessOrEqual(K key,
V val)
Checks to see if this table has a Tuple with a key equal to the key
argument, yet with a value less than or equal to the value argument
provided.
|
boolean |
isDupsEnabled()
Checks to see if this Table has allows for duplicate keys (a.k.a.
|
long |
lessThanCount(K key)
Gets the number of records less than or equal to a key value.
|
void |
put(K key,
V value)
Puts a record into this Table.
|
void |
remove(K key)
Removes all records with a specified key from this Table.
|
void |
remove(K key,
V value)
Removes a single key value pair with a specified key and value from
this Table.
|
org.apache.directory.api.ldap.model.cursor.Cursor<V> |
valueCursor(K key)
Creates a Cursor that traverses Table values for the same key.
