New

static StorageChannelCountProvider New(int channelCount)

Pseudo-constructor method to create a new StorageChannelCountProvider instance using the passed value.

A "channel" is the combination of exclusive storage Thread maintaining an entity registry, data cache, and the like and a storage directory containing storage data files exclusively used by that thread.
The more channels there are, the more parallel loading and storing operations will be executed and the faster the application will become, provided a hardware that can effectively execute that many threads.

Since channels use bitwise modulo hashing, the number of channels must always be a 2^n number with n greater than or equal 0.
(Meaning 1, 2, 4, 8, 16, etc.)

Parameters:

channelCount - the number of channels. Must be a 2^n number with n greater than or equal 0.

Returns:

a new StorageChannelCountProvider instance.

Throws:

IllegalArgumentException - if the passed value is higher than the value returned byStorageChannelCountProvider.Defaults.defaultHighestSaneChannelCount()
