parse

public static IVersionedId parse(String spec)

Creates and returns a new VersionedId from the given string specification. The specification must be of the form "id/version", or just "id" if the version is absent

This factory method can be used to reconstruct a VersionedId instance from the string representation produced by a previous invocation of toString().

Parameters:

spec - the specification for the versioned id to create

Returns:

the parsed versioned id

Throws:

IllegalArgumentException - If spec is improperly formatted.
