Uses of Signal in com.vaadin.signals

Subinterfaces of Signal in com.vaadin.signals

Modifier and Type	Interface	Description
interface	WritableSignal<T>	A signal to which a new value can be directly written.

Methods in com.vaadin.signals that return Signal

Modifier and Type	Method	Description
default Signal<T>	WritableSignal.asReadonly()	Wraps this signal to not accept changes.
static <T> Signal<T>	Signal.computed(SignalComputation<T> computation)	Creates a new computed signal with the given computation callback.
default <C> Signal<C>	Signal.map(SignalMapper<T,C> mapper)	Creates a simple computed signal based on a mapper function that is passed the value of this signal.
static Signal<Boolean>	Signal.not(Signal<Boolean> signal)	Crates a new computed signal containing the negation of the provided boolean-valued signal.

Methods in com.vaadin.signals with parameters of type Signal

Modifier and Type	Method	Description
static Signal<Boolean>	Signal.not(Signal<Boolean> signal)	Crates a new computed signal containing the negation of the provided boolean-valued signal.

Uses of Signal in com.vaadin.signals.impl

Classes in com.vaadin.signals.impl that implement Signal

Modifier and Type	Class	Description
class	ComputedSignal<T>	A signal with a value that is computed based on the value of other signals.
class	MappedModifySignal<P,C>	A writable signal that provides a two-way mapped view of a ValueSignal using in-place modification.
class	MappedWritableSignal<P,C>	A writable signal that provides a two-way mapped view of another writable signal.

Uses of Signal in com.vaadin.signals.local

Classes in com.vaadin.signals.local that implement Signal

Modifier and Type	Class	Description
class	AbstractLocalSignal<T>	Base class for local signals providing shared listener notification, usage tracking, and value access logic.
class	ListSignal<T>	A local list signal that holds a list of writable signals, enabling per-entry reactivity.
class	ValueSignal<T>	A local writable signal that holds a reference to an object.

Uses of Signal in com.vaadin.signals.operations

Classes in com.vaadin.signals.operations with type parameters of type Signal

Modifier and Type	Class	Description
class	InsertOperation<T extends Signal<?>>	An operation that inserts a new child signal into a list or map.

Uses of Signal in com.vaadin.signals.shared

Classes in com.vaadin.signals.shared that implement Signal

Modifier and Type	Class	Description
class	AbstractSignal<T>	Base type for full-featured signals that are backed by a transactional signal tree.
class	SharedListSignal<T>	A signal containing a list of values.
class	SharedMapSignal<T>	A signal containing a map of values with string keys.
class	SharedNodeSignal	A signal representing a node in a tree structure.
class	SharedNumberSignal	A signal containing a numeric value.
class	SharedValueSignal<T>	A signal containing a value.

Methods in com.vaadin.signals.shared that return Signal

Modifier and Type	Method	Description
<C> Signal<C>	SharedNumberSignal.mapIntValue(IntFunction<C> mapper)	Creates a computed signal based on an integer mapper function that is passed the value of this signal.
