Method Detail

getItemsOrdered

public java.util.List getItemsOrdered(java.lang.Object key)
                               throws StorageException

Returns a list view of the values associated in the index with specified key. Returned collection is read only and may not be modified. If there are no values associated with the key empty collection is returned.

Specified by:

getItemsOrdered in interface MultivaluedOrderedIndex

Parameters:

key -

Returns:

Throws:

StorageException

getObjectsOrdered

public java.util.Collection getObjectsOrdered(java.lang.Object key,
                                     SinglevaluedIndex repos)
                                       throws StorageException

Like getItemsOrdered, but if the index contains keys, this returns the objects corresponding to the key

Specified by:

getObjectsOrdered in interface MultivaluedOrderedIndex

Parameters:

key -

Returns:

Throws:

StorageException

add

public void add(java.lang.Object key,
       int index,
       java.lang.Object data)
         throws StorageException

Inserts the specified element at the specified position in the list of values associated with the specified key. Throws StorageBadRequestException if the index is out of range.

Specified by:

add in interface MultivaluedOrderedIndex

Parameters:

key -

index -

value -

Throws:

StorageException

add

public void add(java.lang.Object key,
       java.lang.Object data)
         throws StorageException

Add an item to the end of the list of values for this key.

Specified by:

add in interface Index

Overrides:

add in class MultivaluedBtree

Parameters:

key -

value -

Throws:

StorageBadRequestException - If key or data are incorrect type, or if the insert would violate the constraints of this index

StorageException - If a problem was encountered accessing storage

remove

public boolean remove(java.lang.Object key,
             int index)
               throws StorageException

Removes the element at the specified position in the list of values associated with the specified key.

Specified by:

remove in interface MultivaluedOrderedIndex

Parameters:

key -

index -

Returns:

true if this index changed as a result of this call

Throws:

StorageException

replace

public void replace(java.lang.Object key,
           int index,
           java.lang.Object data)
             throws StorageException

Replaces the element at the specified position in the list of values associated with the specified key with the specified element. Throws StorageBadRequestException if the index is out of range.

Specified by:

replace in interface MultivaluedOrderedIndex
