## Detailed Description

Abstract class that defines the interface for logger appenders.

Event data (LoggerEvent) are formatted before the record is passed to the target

## Member Function Documentation

## serializeImpl()

auto Qore::Logger::LoggerAppenderWithLayout::serializeImpl | ( | LoggerEvent | event | ) |

protected

Serializes the given event to put in the queue or write to the target device.

The appender implementaion can define any format for serialization. The data are passed to processEvent() method in the `params` argument when `type` is `EVENT_LOG`.

Returns
  the serialized event

## setLayout()

Qore::Logger::LoggerAppenderWithLayout::setLayout | ( | LoggerLayout | layout | ) |

Assigns a layout to the appender.

Parameters

  layout | the layout for the appender
