Methods

__construct()

public SetaPDF_Core_Type_HexString::__construct (
[ string $value = null [, boolean $fromString = true [, SetaPDF_Core_Type_AbstractType $owningObject = null ]]]
)

The constructor.

Parameters
$value : string
 
$fromString : boolean
 
$owningObject : SetaPDF_Core_Type_AbstractType
 

__clone()

Implementation of __clone().

__sleep()

public SetaPDF_Core_Type_AbstractType::__sleep (
void
): array

Implementation of __sleep.

We remove the observers from all elements because they will get read if they are waked up in an observed object.

_decrypt()

protected SetaPDF_Core_Type_HexString::_decrypt (
void
): string

Decrypts the value.

attach()

Add an observer to the object.

Implementation of the Observer Pattern.

Parameters
$observer : SplObserver
 

cleanUp()

deepClone()

Clone the object recursively in the context of a document.

Parameters
$document : SetaPDF_Core_Document
 

detach()

Detach an observer from the object.

Implementation of the Observer Pattern.

Parameters
$observer : SplObserver
 

detachAll()

Detach all observers from this object.

Be careful with this method!!!

ensure()

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

Returns the main value.

This method is used for automatically resolving of indirect references.

Parameters
$forceObservation : boolean|null
 

getValue()

public SetaPDF_Core_Type_HexString::getValue (
[ boolean $asString = true ]
): string

Get the value.

If $asString is set to true the value will be passed to the hex2str() method before it is returned.
