Class Symfony\Component\Config\Definition\PrototypedArrayNode

Sets the minimum number of elements that a prototype based node must contain. By default this is zero, meaning no elements.

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:

[ ['id' => 'my_name', 'foo' => 'bar'], ];

becomes

[ 'my_name' => ['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.

Retrieves the name of the attribute which value should be used as key.

Sets the default value of this node.

Returns true when the node has a default value.

Adds default children when none are set.

The default value could be either explicited or derived from the prototype default value.

Sets the node prototype.

Retrieves the prototype.

Disable adding concrete children for prototyped nodes.

Finalizes a value.

Normalizes the value.

Merges two values together.

Returns a prototype for the child node that is associated to $key in the value array. For general child nodes, this will be $this->prototype. But if $this->removeKeyAttribute is true and there are only two keys in the child node: one is same as this->keyAttribute and the other is 'value', then the prototype will be different.

For example, assume $this->keyAttribute is 'name' and the value array is as follows:

[ [ 'name' => 'name001', 'value' => 'value001' ] ]

Now, the key is 0 and the child node is:

[ 'name' => 'name001', 'value' => 'value001' ]

When normalizing the value array, the 'name' element will removed from the child node and its value becomes the new key of the child node:

[ 'name001' => ['value' => 'value001'] ]

Now only 'value' element is left in the child node which can be further simplified into a string:

['name001' => 'value001']

Now, the key becomes 'name001' and the child node becomes 'value001' and the prototype of child node 'name001' should be a ScalarNode instead of an ArrayNode instance.

An array of the prototypes of the simplified value children
