EnumSet

EnumSet is a library which adds a class similar to Java's EnumSet, whose purpose is to perform Set operations on enums faster than a normal Set would.

Specification

EnumSet

size

Gets the number of entries in the EnumSet.

add(value)

Adds the value to the EnumSet. Returns the EnumSet object.

clear()

Removes all elements from the EnumSet object.

delete(value)

Removes the value from the EnumSet, and returns a boolean representing whether or not the value was actually in the EnumSet.

entries()

Returns a new EnumSetIterator object that contains an array of [value, value] for each element in the EnumSet object. Insertion order is not preserved.

forEach(callbackFn[, thisArg])

Calls callbackFn once for each value present in the EnumSet. If a thisArg parameter is provided to forEach, it will be used as the this value for each callback.

has(value)

Returns a boolean asserting whether an element is present in this EnumSet object or not.

keys()

Is the same function as the values() function and returns a new EnumSetIterator object that contains the values for each element in the EnumSet.

values()

Returns a new EnumSetIterator object that contains the values for each element in the EnumSet.

EnumSetIterator

next()

Gets the next entry, if it exists. The returned object is in the form {value, done} where value is specified in the method which returns this EnumSetIterator, or undefined if there are no more values, and done is a boolean which represents whether or not there are additional values in the EnumSet.
