Singleton

abstract class Singleton

An abstraction to apply to singleton instances for uniform initialization.

Properties

static protected Singleton[] $_instances

Methods

__construct()

Require a protected constructor so existing instances can be checked against.

static Singleton
instance(mixed $args = null)

Maybe initialize singleton instance and return the instance.

static array
get_instances()

Return a copy of the instances array.

ReflectionClass
get_class_reflection()

A short one-liner tool to get a ReflectionClass so we can get runtime info for the static class instance and not this abstract.
