|
Returns a stream that applies the unary operator to the stream values of the receiver. Usually, this is the result of applying a unary operator (i.e. a method with one argument) to a pattern.
|
||
|
|
|
||
|
|
Examples of unary operators are: squared, sqrt, sin, tan ...
|

argument::operator
|
||
|
|
operator to be applied
|

|
||
|
|
argument::a
|

a pattern (or compatible pattern input)
