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.

See Also:

format(), forVersionName(String), forBranchName(String)

isBranch

public abstract boolean isBranch()

Returns true if this key identifies a dataspace.

isVersion

public final boolean isVersion()

Returns true 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.
