GenericEvent

class GenericEvent extends Event implements ArrayAccess, IteratorAggregate

Event encapsulation class.

Encapsulates events thus decoupling the observer from the subject they encapsulate.

Methods

bool isPropagationStopped()

Returns whether further event listeners should be triggered.

from Event
stopPropagation()

Stops the propagation of the event to further event listeners.

from Event
__construct(mixed $subject = null, array $arguments = array())

Encapsulate an event with $subject and $args.

mixed getSubject()

Getter for subject property.

mixed getArgument(string $key)

Get argument by key.

GenericEvent setArgument(string $key, mixed $value)

Add argument to event.

array getArguments()

Getter for all arguments.

GenericEvent setArguments(array $args = array())

Set args property.

bool hasArgument(string $key)

Has argument.

mixed offsetGet(string $key)

ArrayAccess for argument getter.

offsetSet(string $key, mixed $value)

ArrayAccess for argument setter.

offsetUnset(string $key)

ArrayAccess for unset argument.

bool offsetExists(string $key)

ArrayAccess has argument.

ArrayIterator getIterator()

IteratorAggregate for iterating over the object like an array.

Details

bool isPropagationStopped()

Returns whether further event listeners should be triggered.

Return Value

bool Whether propagation was already stopped for this event

Event::stopPropagation()

stopPropagation()

Stops the propagation of the event to further event listeners.

If multiple event listeners are connected to the same event, no further event listener will be triggered once any trigger calls stopPropagation().

__construct(mixed $subject = null, array $arguments = array())

Encapsulate an event with $subject and $args.

Parameters

mixed $subject The subject of the event, usually an object
array $arguments Arguments to store in the event

mixed getSubject()

Getter for subject property.

Return Value

mixed $subject The observer subject

mixed getArgument(string $key)

Get argument by key.

Parameters

string $key Key

Return Value

mixed Contents of array key

Exceptions

InvalidArgumentException If key is not found.

GenericEvent setArgument(string $key, mixed $value)

Add argument to event.

Parameters

string $key Argument name
mixed $value Value

array getArguments()

Getter for all arguments.

Return Value

array

GenericEvent setArguments(array $args = array())

Set args property.

Parameters

array $args Arguments

Return Value

bool hasArgument(string $key)

Has argument.

Parameters

mixed offsetGet(string $key)

ArrayAccess for argument getter.

Parameters
