  - {@link oaj.http.annotation.FormData#multipleOf() multipleOf} - Input validation. Number must be a multiple of.
  - {@link oaj.http.annotation.FormData#name() name} - Form data entry name.
  - {@link oaj.http.annotation.FormData#pattern() pattern}- Input validation. Must match regular expression.
  - {@link oaj.http.annotation.FormData#required() required}- Input validation. Form data entry must be present.
  - {@link oaj.http.annotation.FormData#serializer() serializer}- Override the part serializer.
  - {@link oaj.http.annotation.FormData#skipIfEmpty() skipIfEmpty}- Don't add if value is null or empty.
  - {@link oaj.http.annotation.FormData#type() type} - The schema type.
  - {@link oaj.http.annotation.FormData#uniqueItems() uniqueItems} - Input validation. Collections must contain unique items only.

##### Example:

@Remote(path="/myproxy") public interface MyProxy { // Explicit names specified for form data parameters. @RemoteMethod String postParameters( @FormData("foo") String foo, @FormData("bar") MyPojo pojo ); // Multiple values pulled from a NameValuePairs object. // Name "*" is inferred. @RemoteMethod String postNameValuePairs(@FormData NameValuePairs nameValuePairs); // Multiple values pulled from a Map. @RemoteMethod String postMap(@FormData Map<String,Object> map); // Multiple values pulled from a bean. @RemoteMethod String postBean(@FormData MyBean bean); // An entire form-data HTTP body as a String. @RemoteMethod String postString(@FormData String string); // An entire form-data HTTP body as a Reader. @RemoteMethod String postReader(@FormData Reader reader); }

Single-part arguments (i.e. those with name != "*") can be any of the following types:

- Any serializable POJO - Converted to a string using the {@link oaj.httppart.HttpPartSerializer} registered with the RestClient ({@link oaj.oapi.OpenApiSerializer} by default) or associated via the {@link oaj.http.annotation.FormData#serializer() @FormData(serializer)} annotation.

Multi-part arguments (i.e. those with name == "*" or empty) can be any of the following types:

- {@link java.io.Reader} - Raw contents of {@code Reader} will be serialized to remote resource.
- {@link java.io.InputStream} - Raw contents of {@code InputStream} will be serialized to remote resource.
- NameValuePairs - Converted to a URL-encoded FORM post.
- Map - Converted to key-value pairs.
  Values serialized using the registered {@link oaj.httppart.HttpPartSerializer} ({@link oaj.oapi.OpenApiSerializer} by default).
- Bean - Converted to key-value pairs.
  Values serialized using the registered {@link oaj.httppart.HttpPartSerializer} ({@link oaj.oapi.OpenApiSerializer} by default).
- CharSequence - Used directly as am "application/x-www-form-urlencoded" entity.
