Member Function Documentation

execute()

ApiQueryReferences::execute

(

)

Evaluates the parameters, performs the requested query, and sets up the result.

Concrete implementations of ApiBase must override this method to provide whatever functionality their module offers. Implementations must not produce any output on their own and are not expected to handle any errors.

The execute() method will be invoked directly by ApiMain immediately before the result of the module is output. Aside from the constructor, implementations should assume that no other methods will be called externally on the module before the result is processed.

The result data should be stored in the ApiResult object available through getResult().

Reimplemented from ApiBase.

getAllowedParams()

ApiQueryReferences::getAllowedParams

(

)

Returns an array of allowed parameters (parameter name) => (default value) or (parameter name) => (array with PARAM_* constants as keys) Don't call this function directly: use getFinalParams() to allow hooks to modify parameters as needed.

Some derived classes may choose to handle an integer $flags parameter in the overriding methods. Callers of this method can pass zero or more OR-ed flags like GET_VALUES_FOR_HELP.

Returns

array
