final class PhabricatorCachedClassMapQuery
Phorge Technical Documentation (Cache)

Cached PhutilClassMapQuery which can perform lookups for single classes efficiently.

Some class trees (like Conduit methods and PHID types) contain a huge number of classes but are frequently accessed by looking for a specific class by a known identifier (like a Conduit method name or a PHID type constant).

Loading the entire class map for these cases has a small but measurable performance cost. Instead, we can build a cache from each Conduit method name to just the class required to serve that request. This means that we load fewer classes and have less overhead to execute API calls.

public function getPhobjectClassConstant($key, $byte_limit)
Inherited

Phobject

Read the value of a class constant.

This is the same as just typing self::CONSTANTNAME, but throws a more useful message if the constant is not defined and allows the constant to be limited to a maximum length.

Parameters
string$keyName of the constant.
int|null$byte_limitMaximum number of bytes permitted in the value.
Return
stringValue of the constant.
