Value members

Abstract methods

def empty[K, V]: CC[K, V]

An empty Map

An empty Map

def from[K, V](it: IterableOnce[(K, V)]): CC[K, V]

A collection of type Map generated from given iterable object.

A collection of type Map generated from given iterable object.

def fromSpecific(it: IterableOnce[A]): C
Implicitly added by toFactory
Value Params
it

Source collection

Returns

A collection of type C containing the same elements as the source collection it.

def newBuilder: Builder[A, C]
Implicitly added by toFactory

Get a Builder for the collection.

Get a Builder for the collection. For non-strict collection types this will use an intermediate buffer. Building collections with fromSpecific is preferred because it can be lazy for lazy collections.

def newBuilder(from: From): Builder[A, C]
Implicitly added by toBuildFrom

Get a Builder for the collection.

Get a Builder for the collection. For non-strict collection types this will use an intermediate buffer. Building collections with fromSpecific is preferred because it can be lazy for lazy collections.

def newBuilder[K, V]: Builder[(K, V), CC[K, V]]

The default builder for Map objects.

The default builder for Map objects.

Concrete methods

def apply[K, V](elems: (K, V)*): CC[K, V]

A collection of type Map that contains given key/value bindings.

A collection of type Map that contains given key/value bindings.

def toFactory(from: From): Factory[A, C]
Implicitly added by toBuildFrom

Partially apply a BuildFrom to a Factory
