SchemaHandle::read_element_metadata │ private static │ WC 1.0

Read field-/arg-/enum-value-level metadata from the original config array.

FieldDefinition, Argument, InputObjectField and EnumValueDefinition all preserve their construction config in a public $config property, so the metadata key emitted by ApiBuilder is reachable here without any wrapper-side plumbing.

Method of the class: SchemaHandle{}

No Hooks.

Returns

Array. bool|int|float|string|null>

Usage

$result = SchemaHandle::read_element_metadata( $element ): array;
$element(object) (required)
FieldDefinition | Argument | InputObjectField | EnumValueDefinition.
