Class Method Details

.api_method(name, options = {}) ⇒ Object

API methods have a name, which must be the Ruby method name to use when performing the invocation on the web service object.

The signatures for the method input parameters and return value can by specified in options.

A signature is an array of one or more parameter specifiers. A parameter specifier can be one of the following:

  • A symbol or string representing one of the Action Web Service base types. See ActionWebService::SignatureTypes for a canonical list of the base types.

  • The Class object of the parameter type

  • A single-element Array containing one of the two preceding items. This will cause Action Web Service to treat the parameter at that position as an array containing only values of the given type.

  • A Hash containing as key the name of the parameter, and as value one of the three preceding items

If no method input parameter or method return value signatures are given, the method is assumed to take no parameters and/or return no values of interest, and any values that are received by the server will be discarded and ignored.

Valid options:

:expects

Signature for the method input parameters

:returns

Signature for the method return value

:expects_and_returns

Signature for both input parameters and return value
