Runtime: Node.js and browsers

Basic Example

const { ArrayHandler } = require('@livy/array-handler')

// ...use handler in a logger...

// Print all records the handler received
console.log(handler.records)

Public API

See also: Bubbling

level

The minimum log level of a log record to be considered by this handler. Initially set through the level option.

records (read-only)

The records property exposes all log records stored inside the ArrayHandler.

processors

This handler supports processors by implementing the ProcessableHandlerInterface.

reset()

This handler implements the ResettableInterface. Resetting it clears its records and resets all attached processors.

You usually don't want to call this method manually on an individual handler. Consider calling it on the logger instead.
