Class FunctionResource

java.lang.Object
  org.odata4j.producer.resources.BaseResource
      org.odata4j.producer.resources.FunctionResource

public class FunctionResource
extends BaseResource

Handles function calls.

Unfortunately the OData URI scheme makes it impossible to differentiate a function call "resource" from an EntitySet. So, we hack: EntitiesRequestResource delegates to this class if it determines that a function is being referenced.

TODO:
• function parameter facets (required, value ranges, etc). For now, all validation is up to the function handler in the producer.
• non-simple function parameter types
• make sure this works for GET and POST
