Interface NFEIdGenerator

All Known Implementing Classes:

NFEDBSequenceIdGenerator

public interface NFEIdGenerator

Implementations of this interface must provide ID's for a given entity. For example, an instance of NFEIdGenerator my be used to retrieve new IDs for NFEFeatureClass instances. This interfaces hides the complexities of how new IDs are generated. It does not matter if a database sequence is used or if the ID is based on a counter in memory.

Method Summary

Modifier and Type	Method and Description
int	getIdBufferSize() Returns the size of the ID buffer.
long	getNextId() Gets the next ID
void	setIdBufferSize(int size) Sets the size of the ID buffer size used by this generator.

Method Detail

getNextId

long getNextId()

Gets the next ID

Returns:

a new ID

setIdBufferSize

void setIdBufferSize(int size)

Sets the size of the ID buffer size used by this generator. There is not guaranteed that the implementation actually uses a buffer.

Parameters:

size - the number of IDs that can contain the buffer

getIdBufferSize

int getIdBufferSize()

Returns the size of the ID buffer. The size is the number of IDs that the buffer can hold or that are reserved.

Returns:

the size of the ID buffer
