public static IVersionedId parse(java.lang.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:

java.lang.IllegalArgumentException - If spec is improperly formatted.

getId

public java.lang.String getId()

getId in interface IVersionedId

Returns:

the ID of this VersionedID

getVersion

public Version getVersion()

Description copied from interface: IVersionedId

Returns the version portion of this versioned id.

Specified by:

getVersion in interface IVersionedId

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode
