1. Introduction

These definitions can be used in all other BONDI modules as dependencies.

2. Type Definitions

2.1. StringArray

Array of DOMStrings. 

        typedef sequence<DOMString> StringArray;

2.2. ByteArray

Array of 8-bit unsigned integer values. 

        typedef sequence<octet>     ByteArray;

2.3. ShortArray

Array of 16-bit signed integer values. 

        typedef sequence<short>       ShortArray;

2.4. LongArray

Array of 32-bit signed integer values. 

        typedef sequence<long>      LongArray;

2.5. FloatArray

Array of floating point values. 

        typedef sequence<float>     FloatArray;

3. Interfaces

3.1. SuccessCallback

Generic success callback interface. 

        [Callback] interface SuccessCallback {
                void onSuccess(in Object ob);
        };

3.2. ErrorCallback

Generic error callback interface. 

        [Callback] interface ErrorCallback {
                void onError(in Error error);
        };

3.4. DeviceAPIError

Generic error interface. 

        interface DeviceAPIError : GenericError {

                const unsigned short UNKNOWN_ERROR           = 10000;

                const unsigned short INVALID_ARGUMENT_ERROR  = 10001;

                const unsigned short NOT_FOUND_ERROR         = 10002;

                const unsigned short PENDING_OPERATION_ERROR = 10003;

                const unsigned short IO_ERROR                = 10004;

                const unsigned short NOT_SUPPORTED_ERROR     = 10005;
        };

The error codes must be in the range 10000-19999.

This interface inherits from: GenericError

Constants

unsigned short UNKNOWN_ERROR

Unknown error.

unsigned short INVALID_ARGUMENT_ERROR

Invalid value was specified as input parameter.

unsigned short NOT_FOUND_ERROR

The searched value or object was not found.

unsigned short PENDING_OPERATION_ERROR

Operation is pending.

unsigned short IO_ERROR

Input/Output error.

unsigned short NOT_SUPPORTED_ERROR

Not supported error.

3.5. SecurityError

Security error interface. 

        interface SecurityError : GenericError {
                const unsigned short PERMISSION_DENIED_ERROR = 20000;
        };

The error codes must be in the range 20000-29999

This interface inherits from: GenericError

3.6. PendingOperation

PendingOperation. 

        interface PendingOperation {
                boolean cancel();
        };

Interface that is returned by asynchronous operations in order to provide a cancellation operation.

Methods

cancel

Call to cancel the underlying asynchronous operation.

Signature
boolean cancel();

This call is always successful, i.e. the pending operation i.e. either cancelled or one of the callback is called.

Return value
false if one of the callback functions supplied to the operation being cancelled has been called during the call to this method, true otherwise, i.e. the pending operation was cancelled and it was accomplished neither successfully nor errorenously.

3.7. bondi

BONDI root API. 

        [NoInterfaceObject]
        interface bondi {
                PendingOperation requestFeature(in SuccessCallback successCallback,
                                                in ErrorCallback   errorCallback,
                                                in DOMString       name)
                        raises(DeviceAPIError, SecurityError);
        };

Methods

requestFeature

Requests a feature.

Signature
PendingOperation requestFeature(SuccessCallback successCallback, ErrorCallback errorCallback, DOMString name);

This function requests a named feature asynchronously and returns a pending operation object. If it succeeds it calls the successCallback and passes in the object of the requested feature. If it fails it calls the errorCallback passing in a DeviceAPIError which provides an error message and error code indicating the nature of the error.

If the requested feature binds itself to a root namespace ( for example, "bondi.pim.contact") this will happen prior to the successCallback being invoked.

The errorCallback will receive one of the following errors:
DeviceAPIError INVALID_ARGUMENT_ERROR if a malformed argument has been supplied or a required argument has been omitted.
DeviceAPIError NOT_FOUND_ERROR if the requested feature could not be found.
SecurityError PERMISSION_DENIED_ERROR if the requested feature is not permitted to load/bind or that access to a required device capability has been denied.
DeviceAPIError UNKNOWN_ERROR if any other error occurred.

Parameters
  • successCallback: the success callback function
  • errorCallback: the error callback function
  • name: the feature name IRI
Return value
PendingOperation enabling the requester to cancel this request.
Exceptions
  • DeviceAPIError: UNKNOWN_ERROR if an error occurred and a pending operation object can't be returned.
  • SecurityError: PERMISSION_DENIED_ERROR if the requested feature is not permitted to load/bind
