QueryCache::parse_and_cache │ private │ WC 1.0

Parse a query, cache the resulting AST, and return the DocumentNode.

Writes to OPcache when enabled and usable. APQ registrations always also write to the object cache so hash-only lookups still resolve if OPcache later becomes unavailable (toggle off, dir unwritable, files cleaned up, or a silent write_to_opcache failure).

Returns an error array if the query has a syntax error.

Method of the class: QueryCache{}

No Hooks.

Returns

DocumentNode|Array.

Usage

// private - for code of main (parent) class only
$result = $this->parse_and_cache( $query, $hash, $for_apq );
$query(string) (required)
The GraphQL query string.
$hash(string) (required)
The SHA-256 hash to cache under.
$for_apq(true|false)
Whether the request is an APQ registration.
Default: false
