Constructor Summary

HashedVector()

HashedVector(int ignoreCase)
HashedVector will have case-sensitive keying unless ignoreCase is StringSet.IGNORE_CASE

Method Summary

boolean	addElement(java.lang.String key, java.lang.Object object) add Object using key (default case-sensitive).
HashedVector	andIn(HashedVector h2) get elements common to both sets (crude and slow)
boolean	containsObjectWithKey(java.lang.String key) has key been used to store an object?
java.lang.Object	getObject(java.lang.String key) return object with key key, else null
StringSet	getStringSet() return set of all keys (often the names of objects)
int	indexOf(java.lang.String key) serial number of object with key, else -1
HashedVector	notIn(HashedVector h2) get elements NOT in second Set (crude and slow)
HashedVector	orIn(HashedVector h2) get elements in either set (crude and slow)
HashedVector	xorIn(HashedVector h2) get elements in not more than one set (crude and slow)
