Hash

Extends:

Input → BaseText → Hex → Hash

Hash input.

const input = Input.create('myInput: hash', {size: 64});
input.setValue('b542f74248124c32');

Property Summary

Property Name	Description	Defined by Default	Default Value
size	bit size of the hash. This property needs to be defined at constructor time

All properties including the inherited ones can be listed via registeredPropertyNames

Method Summary

Public Methods
public	setRandom() Generates a new random hash and assigns it to the value of the input.

Protected Methods
protected	_validation(at: null \| number): Promise<*> Implements input's validations

Inherited Summary

From class Input
public static	create(inputInterface: string, properties: Object, extendedValidation: function): Input Creates an input instance.
public static	register(inputClass: Input, name: string) Registers a new input type to the available inputs
public static	registerProperty(inputClassOrRegisteredName: string \| Input, name: string, initialValue: *) Registers a property for the input type (also available as `Mebo.Input.registerProperty`)
public static	registeredInput(name: string): Input Returns the input type based on the registration name
public static	registeredInputNames(): Array<string> Returns a list containing the names of the registered input types
public static	registeredPropertyNames(inputClassOrRegisteredName: string \| Input): Array<string> Returns a list about all registered property names including the inherited ones for the input type
protected static	_decodeScalar(value: string): * Decodes the input value from the string representation (Input._encodeScalar) to the data type of the input.
protected static	_decodeVector(value: string): * Decodes a vector value from the string representation ({Input._encodeScalar & Input._encodeVector) to the data type of the input.
protected static	_encodeScalar(value: *): string Encodes the input value to a string representation that can be later decoded through Input._decode.
protected static	_encodeVector(values: Array<string>): string Encodes a vector value to a string representation that can be later decoded through Input._decodeVector.
public	assignProperty(name: string, value: *, loose: boolean) Sets a property to the input.
public	cache(): ImmutableMap Returns the cache used by the input
public	clearCache() Forces to flush the internal input cache
public	hasProperty(name: string): boolean Returns a boolean telling if the input property name is assigned to the input
public	isEmpty(): boolean Returns if the value of the input is empty.
public	isPropertyLocked(name: string): boolean Returns a boolean telling if the property is locked (Input.lockProperty)
public	isRequired(): boolean Returns if the value of the input is required.
public	isSerializable(): boolean Returns if the input is serializable
public	isVector(): boolean Returns if the value of the input is a vector.
public	lockProperty(name: string, lock: boolean) Prevents a property value to be modified by Input.assignProperty
public	name(): string Returns the name of the input which is defined at construction time (inputs cannot be renamed)
public	parseValue(value: string, assignValue: boolean): * Decodes a value represented as string to the type that is compatible with the input.
public	property(name: string): Promise<*> Returns the property value for the input property name
public	propertyNames(): Array<string> Returns a list containing the property names assigned to the input
public	readOnly(): boolean Returns a boolean telling if the input is in read-only mode.
public	async serializeValue(): Promise<string> This method should return a string representation about the current value in a way that can be recovered later through parseValue.
public	setReadOnly(enable: boolean) Changes the read-only state of the input.
public	setValue(value: *) Sets the value of the input
public	setupFrom(sourceInput: Input, at: null \| number, cache: boolean) Sets the input value by avoiding the overhead that may occur when the same value is used across actions that have the input type, therefore this method avoids the re-computation by copying the caches and value associated with the source input to the current input.
public	async validate(): Promise<*> Executes the input validations (_validation), in case of a failed validation then an exception of type ValidationFail is raised
public	value(): * Returns the value of the input
public	valueAt(index: number): * This method enforces the context of the value being queried.
protected	_getFromCache(name: string, at: null \| number): * Auxiliary method used internally by the input implementations to get a value from the cache
protected	_isCached(name: string, at: null \| number): boolean Auxiliary method used internally by input implementations to check if the key is under the cache
protected	_setToCache(name: string, value: *, at: null \| number) Auxiliary method used internally by input implementations to set a value to the cache
protected	async _validation(at: null \| number): Promise<*> Use this method to implement generic validations for your input implementation.

From class BaseText
protected static	_decodeVector(value: string): * Decodes a vector value from the string representation (Input._encodeVector) to the data type of the input.
protected static	_encodeVector(values: Array<string>): string Encodes a vector value to a string representation that can be later decoded through Input._decodeVector.
public	isEmpty(): boolean Returns if the input is empty
protected	_validation(at: null \| number): Promise<*> Implements input's validations

From class Hex
public	decimalValue(): number Returns the current value in decimal
public	setValueFromDecimal(value: number) Sets the current value from a decimal number
protected	_validation(at: null \| number): Promise<*> Implements input's validations

Public Methods

public setRandom() source

Generates a new random hash and assigns it to the value of the input. This method is not supported by vector inputs.

Protected Methods

protected _validation(at: null | number): Promise<*> source

Implements input's validations

Override:

Hex#_validation

Params:

Name	Type	Attribute	Description
at	null \| number		index used when input has been created as a vector that tells which value should be used

Return:

Promise<*>

value held by the input based on the current context (at)
