lithium\data\source\MongoDb::enabled()

Overrides lithium\data\Source::enabled()
public static method

With no parameter, checks to see if adapter's dependencies are installed. With a parameter, queries for a specific supported feature.

A compatibility layer cannot be detected via extension_loaded(), thus we check for the existence of one of the legacy classes to determine if this adapter can be enabled at all.

Parameters

  • string $feature

    Test for support for a specific feature, i.e. "transactions" or "arrays".

Returns

boolean

Returns true if the particular feature (or if MongoDB) support is enabled, otherwise false.
