SuperCollider CLASSES

Plambda

create a scope (namespace) for enclosed streams

Class Methods

*new (pattern, scope)

Arguments:

pattern

an event stream.

scope

an event with default bindings (can be nil).

Inherited class methods

Instance Methods

Inherited instance methods

Undocumented instance methods

-embedInStream (inval)

-scope

-scope = value

Examples

// Plet, Pget and Plambda.
// Plet(key, stream, return)
// Pget(key, default, repeats)
