$this addDefaultsIfNotSet()

Adds the default value if the node is not set in the configuration.

This method is applicable to concrete nodes only (not to prototype nodes). If this function has been called and the node is not set during the finalization phase, it's default value will be derived from its children default values.

Return Value

$this

$this addDefaultChildrenIfNoneSet(int|string|array|null $children = null)

Adds children with a default value when none are defined.

This method is applicable to prototype nodes only.

Parameters

int|string|array|null

$children

The number of children|The child name|The children names to be added

Return Value

$this

$this requiresAtLeastOneElement()

Requires the node to have at least one element.

This method is applicable to prototype nodes only.

Return Value

$this

$this disallowNewKeysInSubsequentConfigs()

Disallows adding news keys in a subsequent configuration.

If used all keys have to be defined in the same configuration file.

Return Value

$this

$this fixXmlConfig(string $singular, string $plural = null)

Sets a normalization rule for XML configurations.

Parameters

string	$singular	The key to remap
string	$plural	The plural of the key for irregular plurals

Return Value

$this

$this useAttributeAsKey(string $name, bool $removeKeyItem = true)

Sets the attribute which value is to be used as key.

This is useful when you have an indexed array that should be an associative array. You can select an item from within the array to be the key of the particular item. For example, if "id" is the "key", then:

array(
    array('id' => 'my_name', 'foo' => 'bar'),
);

becomes

array(
    'my_name' => array('foo' => 'bar'),
);

If you'd like "'id' => 'my_name'" to still be present in the resulting array, then you can set the second argument of this method to false.

This method is applicable to prototype nodes only.

Parameters

string	$name	The name of the key
bool	$removeKeyItem	Whether or not the key item should be removed

Return Value

$this

$this canBeUnset(bool $allow = true)

Sets whether the node can be unset.

Parameters

bool

$allow

Return Value

$this

$this canBeEnabled()

Adds an "enabled" boolean to enable the current section.

By default, the section is disabled. If any configuration is specified then the node will be automatically enabled:

enableableArrayNode: {enabled: true, ...} # The config is enabled & default values get overridden enableableArrayNode: ~ # The config is enabled & use the default values enableableArrayNode: true # The config is enabled & use the default values enableableArrayNode: {other: value, ...} # The config is enabled & default values get overridden enableableArrayNode: {enabled: false, ...} # The config is disabled enableableArrayNode: false # The config is disabled

Return Value

$this

$this canBeDisabled()

Adds an "enabled" boolean to enable the current section.

By default, the section is enabled.

Return Value

$this

$this performNoDeepMerging()

Disables the deep merging of the node.

Return Value

$this

$this ignoreExtraKeys(bool $remove = true)

Allows extra config keys to be specified under an array without throwing an exception.

Those config values are simply ignored and removed from the resulting array. This should be used only in special cases where you want to send an entire configuration array through a special tree that processes only part of the array.

Parameters

bool

$remove

Whether to remove the extra keys

Return Value

$this

$this normalizeKeys(bool $bool)

Sets key normalization.

Parameters

bool

$bool

Whether to enable key normalization

Return Value

$this

append(NodeDefinition $node)

$node = new ArrayNodeDefinition() ->children() ->scalarNode('foo')->end() ->scalarNode('baz')->end() ->end() ->append($this->getBarNodeDefinition()) ;

Parameters

NodeDefinition

$node
