interface InputOptions<T, TransformT> { alias?: string | undefined; transform?: ((v: TransformT) => T) | undefined; debugName?: string | undefined;}
alias
string | undefinedOptional public name for the input. By default, the class field name is used.
transform
((v: TransformT) => T) | undefinedOptional transform that runs whenever a new value is bound. Can be used to transform the input value before the input is updated.
The transform function can widen the type of the input. For example, consider
an input for disabled. In practice, as the component author, you want to only
deal with a boolean, but users may want to bind a string if they just use the
attribute form to bind to the input via <my-dir input>. A transform can then
handle such string values and convert them to boolean. See: booleanAttribute.
debugName
string | undefinedA debug name for the input signal. Used in Angular DevTools to identify the signal.
