Method Details

current

public IdSegment current()

Description copied from interface: SegmentId

Get the current ID segment being used for generation.

This method returns the segment from which IDs are currently being allocated. The segment contains the range of available IDs and tracks the current position within that range.

Specified by:

current in interface SegmentId

Returns:

The current ID segment

generate

public long generate()

Description copied from interface: IdGenerator

Generate a distributed ID as a long value.

This method generates a unique numeric identifier that is guaranteed to be unique within the distributed system. The exact algorithm used depends on the implementation (e.g., Snowflake, Segment, CosId).

Specified by:

generate in interface IdGenerator

Returns:

A unique distributed ID as a long value
