asString

@Nonnull
public String asString(long id)

Description copied from interface: IdConverter

Convert a long type ID to its String representation.

This method transforms a numeric ID into a string format according to the specific conversion algorithm implemented by the converter. For example, a radix converter might convert the number 12345 to "3d7".

Specified by:

asString in interface IdConverter

Parameters:

id - The long type ID to convert

Returns:

The String representation of the ID

asLong

public long asLong(@Nonnull
 String idString)

Description copied from interface: IdConverter

Convert a String type ID back to its long representation.

This method performs the reverse operation of IdConverter.asString(long), transforming a string ID back into its original numeric form. Implementations should be able to correctly parse strings generated by their IdConverter.asString(long) method.

Specified by:

asLong in interface IdConverter

Parameters:

idString - The String type ID to convert

Returns:

The long representation of the ID

stat

public Stat stat()

Description copied from interface: IdConverter

Get statistical information about this converter.

This method provides basic statistical information about the converter, including its implementation class name.

Specified by:

stat in interface IdConverter

Specified by:

stat in interface Statistical

Returns:

Statistical information about this converter
