Properties

$propagationStopped

private bool $propagationStopped = false

Methods

__construct()

Encapsulate an event with $subject and $arguments.

public __construct([mixed $subject = null ][, array<string|int, mixed> $arguments = [] ]) : mixed
Parameters
$subject : mixed = null

The subject of the event, usually an object or a callable

$arguments : array<string|int, mixed> = []

Arguments to store in the event

getArgument()

Get argument by key.

public getArgument(string $key) : mixed
Parameters
$key : string
Tags
throws
InvalidArgumentException

if key is not found

getArguments()

Getter for all arguments.

public getArguments() : array<string|int, mixed>
Return values
array<string|int, mixed>

getIterator()

IteratorAggregate for iterating over the object like an array.

public getIterator() : ArrayIterator<string, mixed>
Return values
ArrayIterator<string, mixed>

getSubject()

Getter for subject property.

public getSubject() : mixed

hasArgument()

Has argument.

public hasArgument(string $key) : bool
Parameters
$key : string
Return values
bool

isPropagationStopped()

Is propagation stopped?

public isPropagationStopped() : bool

This will typically only be used by the Dispatcher to determine if the previous listener halted propagation.

Return values
bool

offsetExists()

ArrayAccess has argument.

public offsetExists(string $key) : bool
Parameters
$key : string

Array key

Return values
bool

offsetGet()

ArrayAccess for argument getter.

public offsetGet(string $key) : mixed
Parameters
$key : string

Array key

Tags
throws
InvalidArgumentException

if key does not exist in $this->args

offsetSet()

ArrayAccess for argument setter.

public offsetSet(string $key, mixed $value) : void
Parameters
$key : string

Array key to set

$value : mixed

offsetUnset()

ArrayAccess for unset argument.

public offsetUnset(string $key) : void
Parameters
$key : string

Array key

setArgument()

Add argument to event.

public setArgument(string $key, mixed $value) : $this
Parameters
$key : string
$value : mixed
Return values
$this

setArguments()

Set args property.

public setArguments([array<string|int, mixed> $args = [] ]) : $this
Parameters
$args : array<string|int, mixed> = []
Return values
$this

stopPropagation()

Stops the propagation of the event to further event listeners.

public stopPropagation() : void

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