ErrorFactory

interface ErrorFactory<T : AbstractJsException>

JavaScript: Error Factory

All JavaScript exception intrinsics are expected to implement this interface on their companion object; this allows for dynamic extension/implementation of a given JS exception, based on an originating Java exception.

When constructing a JS error from a Java exception, Elide will attempt to use an appropriate JS error type, and will provide the maximum amount of developer ergonomics possible to identify where the error took place.

Parameters

T

type of JavaScript error implemented by this factory. Must implement AbstractJsException.

See also

for the regular object interface implemented for each JS exception type.

Functions

abstract fun create(error: Throwable): T

Create a JavaScript-environment error of type T (an AbstractJsException) which wraps the provided Throwable. Any non-private fields and information on the provided Throwable will be included with the JS error.

abstract fun create(message: String, cause: Throwable? = null): T

Create a JavaScript-environment error of type T (an AbstractJsException) which wraps the provided message string and optional Throwable. Any non-private fields and information on the provided Throwable, if present, will be included with the JS error.
