OrdersTableDataStoreMeta::is_valid_cached_meta │ private │ WC 1.0

Determine whether a cached meta entry is a well-formed array of meta rows.

An empty array is valid: it represents an order with no meta. Each non-empty element must be an object carrying the meta_id, meta_key and meta_value properties that database-backed rows always have (see CustomMetaDataStore::get_meta_data_for_object_ids()) and that downstream consumers read.

Method of the class: OrdersTableDataStoreMeta{}

No Hooks.

Returns

true|false. True when the value is a usable array of meta rows.

Usage

// private - for code of main (parent) class only
$result = $this->is_valid_cached_meta( $object_meta ): bool;
$object_meta(mixed) (required)
The cached value to validate.
