Method Detail
forBranchName
public static final BranchKey forBranchName(String aName)
Returns the dataspace identifier with the specified name.
forVersionName
public static final VersionKey forVersionName(String aName)
Returns the snapshot identifier with the specified name.
parse
public static final HomeKey parse(String aString)
Parses the specified string, so as to return either a dataspace or snapshot key.The specified string must have been generated by
format()
.- Parameters:
aString
- specified string- Throws:
IllegalArgumentException
- If specified string :- is undefined,
- is empty,
- has an illegal prefix character.

format()
,forVersionName(String)
,forBranchName(String)
isBranch
public abstract boolean isBranch()
Returnstrue
if this key identifies a dataspace.
isVersion
public final boolean isVersion()
Returnstrue
if this key identifies a snapshot.
getName
public final String getName()
Returns the string associated with this key.Since the dataspace namespace and the snapshot namespace are independent, the returned string is only an identifier in the context of one of the namespaces. For a global dataspace or snapshot identifier, the method
format()
must be used.- See Also:
format()
format
public final String format()
Returns a persistent identifier of a dataspace or snapshot.Compared to the method
getName()
, this identifier additionally specifies whether this key is for a dataspace or a snapshot.- See Also:
parse(String)
toDisplayString
public final String toDisplayString(Locale aLocale)
Returns a user-friendly string that specifies the type of this key, for example, "Dataspace <name>" or "Snapshot <name>".
