Table of Contents
Interfaces
- InstantiatorInterface
- Instantiator provides utility methods to build objects without invoking their constructors
Constants
- SERIALIZATION_FORMAT_AVOID_UNSERIALIZER = 'O'
- SERIALIZATION_FORMAT_USE_UNSERIALIZER = 'C'
- Markers used internally by PHP to define whether {@see \unserialize} should invoke the method {@see \Serializable::unserialize()} when dealing with classes implementing the {@see \Serializable} interface.
Properties
- $cachedCloneables : array<string|int, object>
- Array of objects that can directly be cloned, indexed by class name.
- $cachedInstantiators : array<string|int, callable>
- Used to instantiate specific classes, indexed by class name.
Methods
- instantiate() : object
- attemptInstantiationViaUnSerialization() : void
- buildAndCacheFromFactory() : object
- Builds the requested object and caches it in static properties for performance
- buildFactory() : callable
- Builds a callable capable of instantiating the given $className without invoking its constructor.
- checkIfUnSerializationIsSupported() : void
- getReflectionClass() : ReflectionClass
- hasInternalAncestors() : bool
- Verifies whether the given class is to be considered internal
- isInstantiableViaReflection() : bool
- isSafeToClone() : bool
- Checks if a class is cloneable
