Summary

Static Methods

Methods

Properties

Properties

$_observed

protected bool SetaPDF_Core_Type_AbstractType::$_observed = false

Defines if this object is under observation

$_observers

protected array SetaPDF_Core_Type_AbstractType::$_observers = array()

The Objects to notify on any change

This will be the PDF document or another value holding this one. Initially this will be an array.

$_value

protected integer|float SetaPDF_Core_Type_Numeric::$_value = 0

The numeric value

$metadata

public array SetaPDF_Core_Type_AbstractType::$metadata = array()

An array for individual metadata.


Static Methods

_ensureType()

protected static SetaPDF_Core_Type_AbstractType::_ensureType (
string $type, mixed $value, string $errorMessage [, $ensure = true ]
): mixed

Ensure that a value is an instance of a specific PDF type.

Parameters
$type : string
 
$value : mixed
 
$errorMessage : string
 
$ensure
 
Exceptions

Throws SetaPDF_Core_Type_Exception

ensure32BitInteger()

public static SetaPDF_Core_Type_Numeric::ensure32BitInteger (
integer $value
): integer

This helper method simulates the overflow behavior of a 32bit system on a 64bit system.

Parameters
$value : integer
 

ensureType()

public static SetaPDF_Core_Type_Numeric::ensureType (
mixed $value
): SetaPDF_Core_Type_Numeric

Ensures that the passed value is a SetaPDF_Core_Type_Numeric instance.

Parameters
$value : mixed
 
Exceptions

Throws SetaPDF_Core_Type_Exception

ensureWithType()

public static SetaPDF_Core_Type_AbstractType::ensureWithType (
string $type, mixed $value
): SetaPDF_Core_Type_AbstractType

Ensures that the passed value is an instance of the passed type.

Parameters
$type : string
 
$value : mixed
 
Exceptions

Throws SetaPDF_Core_Type_Exception

is()

public static SetaPDF_Core_Type_AbstractType::is (
string $type, mixed $value [, bool $ensure = true ]
): bool

Checks if the type of a value is the expected one.

Indirect references will be evaluated if $ensure is set to true.

Parameters
$type : string
 
$value : mixed
 
$ensure : bool
 

writePdfString()

public static SetaPDF_Core_Type_Numeric::writePdfString (
SetaPDF_Core_WriteInterface $writer, integer|float $value
): void

Parses a php integer or float value to a pdf numeric string and write it into a writer.

Parameters
$writer : SetaPDF_Core_WriteInterface
 
$value : integer|float
 
Exceptions

Throws InvalidArgumentException

Methods

__construct()

public SetaPDF_Core_Type_Numeric::__construct (
[ integer|float $value = null ]
)

The constructor.

Parameters
$value : integer|float
 

__clone()

public SetaPDF_Core_Type_AbstractType::__clone (
void
): void

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.

__wakeup()

public SetaPDF_Core_Type_AbstractType::__wakeup (
void
): void

Implementation of __wakeup.

Unset the observed flag.

attach()

public SetaPDF_Core_Type_AbstractType::attach (
SplObserver $observer
): void

Add an observer to the object.

Implementation of the Observer Pattern.

Parameters
$observer : SplObserver
 

cleanUp()

public SetaPDF_Core_Type_AbstractType::cleanUp (
void
): void

This method is used to clean up an object by releasing memory and references.

The observers have to be removed with the "detach()"-method. Only if there is no observer left this method should really release resources.

The method has to be implemented by each object type

deepClone()

public SetaPDF_Core_Type_AbstractType::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 (
SplObserver $observer
): void

Detach an observer from the object.

Implementation of the Observer Pattern.

Parameters
$observer : SplObserver
 

detachAll()

public SetaPDF_Core_Type_AbstractType::detachAll (
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
$forceObservation : bool|null
 

getValue()

public SetaPDF_Core_Type_Numeric::getValue (
void
): float

Ger the numeric value.

See

isObserved()

public SetaPDF_Core_Type_AbstractType::isObserved (
void
): bool

Checks if this object is observed.

notify()

public SetaPDF_Core_Type_AbstractType::notify (
void
): void

Notifies all attached observers.

Implementation of the Observer Pattern.

Has to be called by any method that changes a value.

setValue()

public SetaPDF_Core_Type_Numeric::setValue (
float|integer $value
): void

Set the numeric value.

Parameters
$value : float|integer
 
See

toPdfString()

public SetaPDF_Core_Type_Numeric::toPdfString (
[ SetaPDF_Core_Document|null $pdfDocument = null ]
): string

Returns the type as a formatted PDF string.

Parameters
$pdfDocument : SetaPDF_Core_Document|null
 

toPhp()

public SetaPDF_Core_Type_Numeric::toPhp (
void
): float

Converts the PDF data type to a PHP data type and returns it.

writeTo()

public SetaPDF_Core_Type_Numeric::writeTo (
SetaPDF_Core_Document $pdfDocument
): void

Writes the type as a formatted PDF string to the document.

Parameters
$pdfDocument : SetaPDF_Core_Document
