): void

Implementation of __wakeup.

Unset the observed flag.

attach()

public SetaPDF_Core_Type_Array::attach (

Add an observer to the object.

This method forwards the "attach()"-call to all values of this array.

Parameters
$observer : SplObserver

): int

Returns the number of elements in the array.

current()

public SetaPDF_Core_Type_Array::current (
void
): SetaPDF_Core_Type_AbstractType

Returns the current element.

deepClone()

public SetaPDF_Core_Type_Array::deepClone (): SetaPDF_Core_Type_AbstractType

Clone the object recursively in the context of a document.

Parameters
$document : SetaPDF_Core_Document
 

detach()

public SetaPDF_Core_Type_AbstractType::detach (

void
): void

Detach all observers from this object.

Be careful with this method!!!

ensure()

public SetaPDF_Core_Type_AbstractType::ensure (
[ bool|null $forceObservation = null ]
): SetaPDF_Core_Type_AbstractType

Returns the main value.

This method is used for automatically resolving of indirect references.

Parameters
