Stream contains at least one occurrence of value.
Stream contains at least one occurrence of value.
Channels: Once true, will never produce any other value.
,Buffers: When the item is removed, it will produce false.
Count number of occurrence of value.
Count number of occurrence of value.
Channels: With every matching element, the counter is increased.
,Buffers: When the element is removed, the counter is decreased.

Checks for existence of a value for which f is true
TODO Could this be implemented more efficiently without iterating over elements?

Returns first matching row; if it gets deleted, returns next match.

Checks whether f is true for all elements

Produce a value for the first row. If the list is empty, head does not produce any value. When the first row is deleted, the next row will be produced.

Partial channels: Produce true if the current value is cleared.
,Channels: Produce false with the first received value.
,Buffers: Produce a new value once a row is added or removed.
Last element with the possibility of non-existence

scala.Some with first row, or scala.None if the list is empty
Unlike mapPure, stores mapping locally.
Unlike mapPure, stores mapping locally. This is currently needed as
widget objects are not immutable.
f must not be side-effecting
Negation of isEmpty
Applies partial function f on each element; if the function is not
defined for the current input, it is filtered out

Partitions stream into two sub-stream
Partitions stream into two sub-stream
The left stream contains all elements for which f is true, all other
elements go to the right stream.

The left stream contains all elements for which f is true, all other

State channels: Produce when a new child is attached and if the size changes. In org.widok.Opt the size is reset if the value is cleared.
,Channels: The size is only produced in response to each received value on the channel.
,Buffers: Produce the row count once a row is added or removed.
Splits stream into two sub-streams

The left stream contains all elements as long as f is true, all
subsequent elements go to the right stream.

The left container contains all elements if f is true, all subsequent
elements go to the right container.
