Constructor Detail

NFEDBSequenceIdManager

public NFEDBSequenceIdManager(NFEDataSource dataSource)

Method Detail

setModel

public void setModel(NFEModel model)

Description copied from interface: NFEIdManager

Sets the current NFEModel instance. This is typically set automatically when a new NFEModel instance is initialized.

Specified by:

setModel in interface NFEIdManager

Parameters:

model - an NFEModel instance

getModel

public NFEModel getModel()

Description copied from interface: NFEIdManager

Gets the current NFEModel instance

Specified by:

getModel in interface NFEIdManager

Returns:

the assigned NFEModel instance

setIdGenerator

public void setIdGenerator(java.lang.String entityName,
                           NFEIdGenerator idGen)

Description copied from interface: NFEIdManager

Associates an NFEIdGenerator instance to the given entity. The NFEIdGenerator instance will be used to create new ID's for the entity.

Specified by:

setIdGenerator in interface NFEIdManager

Parameters:

entityName - an entity name. See the field summary for supported entity names.

idGen - an NFEIdGenerator instance

getIdGenerator

public NFEIdGenerator getIdGenerator(java.lang.String entityName)

Description copied from interface: NFEIdManager

Gets the NFEIdGenerator currently used for generating ID's for the given entity

Specified by:

getIdGenerator in interface NFEIdManager

Parameters:

entityName - an entity name.

Returns:

an NFEIdGenerator instance or null if the entity is not related to any ID generator

getNextId

public long getNextId(java.lang.String entityName)

Description copied from interface: NFEIdManager

Gets the next ID for the given entity name. It is equivalent to get the ID generator for the entity and call NFEIdGenerator.getNextId()

Specified by:

getNextId in interface NFEIdManager

Parameters:

entityName - an entity name

Returns:

a valid ID if the entity is related to an ID generator

getNextNodeId

public long getNextNodeId()

Description copied from interface: NFEIdManager

Gets the next node ID. This is a shorthand for getNextId( NFEIdManager.ENTITY_NODE )

Specified by:

getNextNodeId in interface NFEIdManager

Returns:

a node ID

getNextLinkId

public long getNextLinkId()

Description copied from interface: NFEIdManager

Gets the next link ID. This is a shorthand for getNextId( NFEIdManager.ENTITY_LINK )

Specified by:

getNextLinkId in interface NFEIdManager

Returns:

a link ID

getNextFeatureId

public long getNextFeatureId(long featureLayerId)

Description copied from interface: NFEIdManager

Gets the next feature ID for the Feature Layer identified by the given featureLayerId

Specified by:

getNextFeatureId in interface NFEIdManager

Parameters:

featureLayerId - an existing Feature Layer ID

Returns:

a feature ID

getNextFeatureElementSequence

public long getNextFeatureElementSequence(long featureLayerId)

Description copied from interface: NFEIdManager

Gets the next feature element sequence for the Feature Layer identified by the given featureLayerId. Note that the sequence is used as the ID of a feature element. A feature may contain feature element with no necessarily consecutive sequences.

Specified by:

getNextFeatureElementSequence in interface NFEIdManager

Parameters:

featureLayerId - featureLayerId an existing Feature Layer ID

Returns:

a feature element sequence.

setIdBufferSize

public void setIdBufferSize(int size)

Description copied from interface: NFEIdManager

Sets the ID buffer size used by all the ID generators managed

Specified by:

setIdBufferSize in interface NFEIdManager

Parameters:

size - the size of the buffer
