Method Summary

static String	getSignature(Variant variant, StringBuffer sb) Returns a signature for a TopicMap Variant.
static void	removeDuplicateVariants(BaseName basename) The currently-used version of TM4J does not include suppression of duplicate variant names, so this method is used to strip them by creating comparative signatures for each.

Method Detail

removeDuplicateVariants

public static void removeDuplicateVariants(BaseName basename)
                                    throws PropertyVetoException

The currently-used version of TM4J does not include suppression of duplicate variant names, so this method is used to strip them by creating comparative signatures for each.

Throws:

PropertyVetoException

getSignature

public static String getSignature(Variant variant,
                                  StringBuffer sb)

Returns a signature for a TopicMap Variant. This signature is created from the recursive Variant structure by appending identifier strings for each object to a final String signature. This method should be called with a null parameter for the StringBuffer, as this parameter is only used recursively by the method itself.

Parameters:

variant - the variant from which to compute the signature

sb - the StringBuffer to which to append the signature. This should provided as a null.

Returns:

the computed signature
