Method Details

getNamespace

@Nonnull
public String getNamespace()

Description copied from interface: IdSegmentDistributor

Get the namespace for this distributor.

The namespace provides a logical grouping for ID segments, allowing multiple independent segment spaces within the same system.

Specified by:

getNamespace in interface IdSegmentDistributor

Returns:

The namespace

getName

@Nonnull
public String getName()

Description copied from interface: IdSegmentDistributor

Get the name for this distributor.

The name uniquely identifies this distributor within its namespace.

Specified by:

getName in interface IdSegmentDistributor

Returns:

The name

getStep

public long getStep()

Description copied from interface: IdSegmentDistributor

Get the step size for ID segments.

The step size determines how many IDs are allocated in each segment. Larger steps reduce coordination overhead but may lead to ID gaps.

Specified by:

getStep in interface IdSegmentDistributor

Returns:

The step size

nextMaxId

public long nextMaxId(long step)

Description copied from interface: IdSegmentDistributor

Allocate the next maximum ID for the specified step size.

This method allocates a new range of IDs by returning the maximum ID in the allocated range. The range starts at the previous maximum plus one and ends at the returned value.

Specified by:

nextMaxId in interface IdSegmentDistributor

Parameters:

step - The step size for allocation

Returns:

The maximum ID in the allocated range
