PersistedIntSignal class - signals library

Constructors

PersistedIntSignal(int val, String key, {SignalsKeyValueStore? store}): Creates a new IntSignal.

Properties

autoDispose ↔ bool: Throws and error if read after dispose and can be disposed on last unsubscribe.
getter/setter pairinherited
bitLength → int: Available on ReadonlySignal<int>, provided by the IntSignalExtension extension
Returns the minimum number of bits required to store this integer.
no setter
debugLabel → String?: Debug label for Debug Mode
finalinherited
disposed ↔ bool: Check if the effect is disposed
getter/setter pairinherited
equalityCheck ↔ bool Function(int a, int b): Optional method to check if to values are the same
getter/setter pairinherited
globalId → int: Global ID of the signal
finalinherited
hashCode → int: The hash code for this object.
no setterinherited
internalValue → int: no setterinherited
isEven → bool: Available on ReadonlySignal<int>, provided by the IntSignalExtension extension
Returns true if and only if this integer is even.
no setter
isInitialized → bool: Check if a signal value is set (does not subscribe)
no setterinherited
isOdd → bool: Available on ReadonlySignal<int>, provided by the IntSignalExtension extension
Returns true if and only if this integer is odd.
no setter
key → String: The key to use for storing the value.
finalinherited
loaded ↔ bool: Whether the signal has been loaded from the store.
getter/setter pairinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
sign → int: Available on ReadonlySignal<int>, provided by the IntSignalExtension extension
Returns the sign of this integer.
no setter
store → SignalsKeyValueStore: The store to use for storing the value.
finalinherited
value ↔ int: Compute the current value
getter/setter pairinherited
version ↔ int: Version numbers should always be >= 0, because the special value -1 is used by Nodes to signify potentially unused but recyclable nodes.
getter/setter pairinherited

Methods

abs() → int: Available on ReadonlySignal<int>, provided by the IntSignalExtension extension
Returns the absolute value of this integer.
afterCreate(int val) → void: Internal hook for after a signal is created
inherited
beforeUpdate(int val) → void: Internal hook for after a signal is updated
inherited
call() → int: Return the value when invoked
inherited
ceil() → int: Available on ReadonlySignal<int>, provided by the IntSignalExtension extension
Returns this.
ceilToDouble() → double: Available on ReadonlySignal<int>, provided by the IntSignalExtension extension
Returns this.toDouble().
decode(String value) → int: Decodes the value from a string.
override
dispose() → void: Dispose the signal
inherited
encode(int value) → String: Encodes the value to a string.
override
floor() → int: Available on ReadonlySignal<int>, provided by the IntSignalExtension extension
Returns this.
floorToDouble() → double: Available on ReadonlySignal<int>, provided by the IntSignalExtension extension
Returns this.toDouble().
gcd(int other) → int: Available on ReadonlySignal<int>, provided by the IntSignalExtension extension
Returns the greatest common divisor of this integer and other.
get() → int: Helper method to get the current value
inherited
init() → Future<void>: Initializes the signal by loading the value from the store.
inherited
internalRefresh() → bool: inherited
load() → Future<int>: Loads the value from the store.
inherited
modInverse(int modulus) → int: Available on ReadonlySignal<int>, provided by the IntSignalExtension extension
Returns the modular multiplicative inverse of this integer modulo modulus.
modPow(int exponent, int modulus) → int: Available on ReadonlySignal<int>, provided by the IntSignalExtension extension
Returns this integer to the power of exponent modulo modulus.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
onDispose(void cleanup()) → void Function(): Add a cleanup function to be called when the signal is disposed
inherited
overrideWith(int val) → Signal<int>: Override the current signal with a new value as if it was created with it
inherited
peek() → int: In the rare instance that you have an effect that should write to another signal based on the previous value, but you don't want the effect to be subscribed to that signal, you can read a signals's previous value via signal.peek().
inherited
readonly() → ReadonlySignal<int>: Returns a readonly signal
inherited
round() → int: Available on ReadonlySignal<int>, provided by the IntSignalExtension extension
Returns this.
roundToDouble() → double: Available on ReadonlySignal<int>, provided by the IntSignalExtension extension
Returns this.toDouble().
save(int value) → Future<void>: Saves the value to the store.
inherited
set(int val, {bool force = false}) → bool: Set the current value by a method
inherited
subscribe(void fn(int value)) → void Function(): Subscribe to value changes with a dispose function
inherited
subscribeToNode(Node node) → void: inherited
toJson() → dynamic: Convert value to JSON
inherited
toRadixString(int radix) → String: Available on ReadonlySignal<int>, provided by the IntSignalExtension extension
Converts this int to a string representation in the given radix.
toSigned(int width) → int: Available on ReadonlySignal<int>, provided by the IntSignalExtension extension
Returns the least significant width bits of this integer, extending the highest retained bit to the sign. This is the same as truncating the value to fit in width bits using an signed 2-s complement representation. The returned value has the same bit value in all positions higher than width.
toString() → String: A string representation of this object.
inherited
toUnsigned(int width) → int: Available on ReadonlySignal<int>, provided by the IntSignalExtension extension
Returns the least significant width bits of this integer as a non-negative number (i.e. unsigned representation). The returned value has zeros in all bit positions higher than width.
truncate() → int: Available on ReadonlySignal<int>, provided by the IntSignalExtension extension
Returns this.
truncateToDouble() → double: Available on ReadonlySignal<int>, provided by the IntSignalExtension extension
Returns this.toDouble().
unsubscribeFromNode(Node node) → void: inherited
