array<string, mixed>

__get()

Lazy loads helpers.

public __get(string $name) : Helper|null|void
Parameters
$name : string

addClass()

Adds the given class to the element options

public addClass(array<string, mixed> $options, string $class[, string $key = 'class' ]) : array<string, mixed>
Parameters
$options : array<string, mixed>

Array options/attributes to add a class to

$class : string

The class name being added.

$key : string = 'class'

the key to use for class. Defaults to 'class'.

Return values
array<string, mixed>

Array of options with $key set.

configShallow()

Merge provided config with existing config. Unlike `config()` which does a recursive merge for nested keys, this method does a simple merge.

public configShallow(array<string, mixed>|string $key[, mixed|null $value = null ]) : $this

Setting a specific value:

$this->configShallow('key', $value);

Setting a nested value:

$this->configShallow('some.nested.key', $value);

Updating multiple config settings at the same time:

$this->configShallow(['one' => 'value', 'another' => 'value']);
Parameters
$key : array<string, mixed>|string

The key to set, or a complete array of configs.

$value : mixed|null = null

The value to set.

Return values
$this

getConfig()

Returns the config.

public getConfig([string|null $key = null ][, mixed $default = null ]) : mixed

Usage

Reading the whole config:

$this->getConfig();

Reading a specific value:

$this->getConfig('key');

Reading a nested value:

$this->getConfig('some.nested.key');

Reading with default value:

$this->getConfig('some-key', 'default-value');
Parameters
$key : string|null = null

The key to get or null for the whole config.

$default : mixed = null

The return value when the key does not exist.

Return values
mixed

Configuration data at the named key or null if the key does not exist.

getConfigOrFail()

Returns the config for this specific key.

public getConfigOrFail(string $key) : mixed

The config value for this key must exist, it can never be null.

array<string, mixed>

initialize()

Constructor hook method.

public initialize(array<string, mixed> $config) : void

Implement this method to avoid having to overwrite the constructor and call parent.

$RGB : int

The RGB code.

Return values
Hlls

The object containing the info needed.

setConfig()

Sets the config.

public setConfig(array<string, mixed>|string $key[, mixed|null $value = null ][, bool $merge = true ]) : $this

Setting a nested value:

$this->setConfig('some.nested.key', $value);

Updating multiple config settings at the same time:

$this->setConfig(['one' => 'value', 'another' => 'value']);
Parameters
$key : array<string, mixed>|string

The key to set, or a complete array of configs.

$value : mixed|null = null

The value to set.

$merge : bool = true
