Class goog.structs.StringSet

Creates a set of strings.

Instance Method Summary
	`__iterator__(boolean= opt_keys) ⇒ !goog.iter.Iterator` Returns an iterator that iterates over the elements in the set. NOTE: creating the iterator copies the whole set so use {@link #forEach} when possible.
	`add(<Any Type> element)` Adds a single element to the set.
	`addArray(!Array arr)` Adds a the elements of an array to this set.
	`addDifference_(!goog.structs.StringSet set1, !goog.structs.StringSet set2)` Adds the elements which are in {@code set1} but not in {@code set2} to this set.
	`addSet(!goog.structs.StringSet stringSet)` Adds a the elements of a set to this set.
	`clear()` Removes all elements of the set.
	`clone() ⇒ !goog.structs.StringSet`
	`contains(<Any Type> element) ⇒ boolean` Tells if the set contains the given element.
	`containsArray(!Array arr) ⇒ boolean` Tells if the set contains all elements of the array.
	`decode(string key) ⇒ string` Inverse function of {@link #encode}. NOTE: forEach would be 30% faster in FF if the compiler inlined decode.
	`encode(<Any Type> element) ⇒ <Any Type>` The '__proto__' and the '__count__' keys aren't enumerable in Firefox, and 'toString', 'valueOf', 'constructor', etc. aren't enumerable in IE so they have to be escaped before they are added to the internal object. NOTE: When a new set is created, 50-80% of the CPU time is spent in encode.
	`equals(!goog.structs.StringSet stringSet) ⇒ boolean` Tells if this set has the same elements as the given set.
	`forEach(function (string, undefined, goog.structs.StringSet): ? f, ?Object= opt_obj)` Calls a function for each element in the set.
	`getCount() ⇒ number` Counts the number of elements in the set in linear time. NOTE: getCount is always called at most once per set instance in google3. If this usage pattern won't change, the linear getCount implementation is better, because populating a set and getting the number of elements in it takes the same amount of time as keeping a count_ member up to date and getting its value; if getCount is not called, adding and removing elements have no overhead.
	`getDifference(!goog.structs.StringSet stringSet) ⇒ !goog.structs.StringSet` Calculates the difference of two sets.
	`getIntersection(!goog.structs.StringSet stringSet) ⇒ !goog.structs.StringSet` Calculates the intersection of this set with another set.
	`getSymmetricDifference(!goog.structs.StringSet stringSet) ⇒ !goog.structs.StringSet` Calculates the symmetric difference of two sets.
	`getUnion(!goog.structs.StringSet stringSet) ⇒ !goog.structs.StringSet` Calculates the union of this set and another set.
	`getValues() ⇒ !Array`
	`isDisjoint(!goog.structs.StringSet stringSet) ⇒ boolean` Tells if this set and the given set are disjoint.
	`isEmpty() ⇒ boolean`
	`isSubsetOf(!goog.structs.StringSet stringSet) ⇒ boolean` Tells if this set is the subset of the given set.
	`isSupersetOf(!goog.structs.StringSet stringSet) ⇒ boolean` Tells if this set is the superset of the given set.
	`remove(<Any Type> element) ⇒ boolean` Removes a single element from the set.
	`removeArray(!Array arr)` Removes all elements of the given array from this set.
	`removeSet(!goog.structs.StringSet stringSet)` Removes all elements of the given set from this set.
