AbstractLogger:: (8 methods):
  emergency()
  alert()
  critical()
  error()
  warning()
  notice()
  info()
  debug()


Class: AbstractLogger  - X-Ref

This is a simple Logger implementation that other Loggers can inherit from.

It simply delegates all log-level-specific methods to the `log` method to
reduce boilerplate code that a simple Logger that does the same thing with
messages regardless of the error level has to implement.
emergency($message, array $context = array()   X-Ref
System is unusable.

return: void
param: string  $message
param: mixed[] $context

alert($message, array $context = array()   X-Ref
Action must be taken immediately.

Example: Entire website down, database unavailable, etc. This should
trigger the SMS alerts and wake you up.

return: void
param: string  $message
param: mixed[] $context

critical($message, array $context = array()   X-Ref
Critical conditions.

Example: Application component unavailable, unexpected exception.

return: void
param: string  $message
param: mixed[] $context

error($message, array $context = array()   X-Ref
Runtime errors that do not require immediate action but should typically
be logged and monitored.

return: void
param: string  $message
param: mixed[] $context

warning($message, array $context = array()   X-Ref
Exceptional occurrences that are not errors.

Example: Use of deprecated APIs, poor use of an API, undesirable things
that are not necessarily wrong.

return: void
param: string  $message

notice($message, array $context = array()   X-Ref
Normal but significant events.

return: void
param: string  $message

info($message, array $context = array()   X-Ref
Interesting events.

Example: User logs in, SQL logs.
