Method Detail

recursivelyFlatten

public static java.util.Vector recursivelyFlatten(java.util.Collection in)

recursive flattening of the incoming collection. self-referential objects will loop forever.

Parameters:

in - something to iterate over; null pointers return null results

Returns:

a vector containing everything in the collection, apart from collection objects, which are themselves flattened.

crack

public static java.util.Vector crack(java.lang.String uriList)

split a list of string values into separate elements of a vector. dumb simple parsing

Parameters:

uriList -

Returns:

the string cracked; may be empty for no interesting content

mergeDuplicates

public static java.util.Vector mergeDuplicates(java.util.Collection source)

eliminate all duplicate entries from a vector. uses a hash table, O(n*(O(hashtable add)+O(hashtable lookup))

Parameters:

source -

Returns:

makeSpaceSeparatedString

public static java.lang.String makeSpaceSeparatedString(java.util.Vector source)

turn a vector of strings into a space separated list

Parameters:

source -

Returns:

makeResource

public static java.lang.String makeResource(java.lang.String classname)

convert a classname to a resource

Parameters:

classname -

Returns:

resource
