Detailed Description

YFunction Class: Common function interface

This is the parent class for all public objects representing device functions documented in the high-level programming API. This abstract class does all the real job, but without knowledge of the specific function attributes.

Instantiating a child class of YFunction does not cause any communication. The instance simply keeps track of its function identifier, and will dynamically bind to a matching device at the time it is really being used to read or set an attribute. In order to allow true hot-plug replacement of one device by another, the binding stay dynamic through the life of the object.

The YFunction class implements a generic high-level cache for the attribute values of the specified function, pre-parsed from the REST API string.

Invalidates the cache. Invalidates the cache of the function attributes. Forces the next call to get_xxx() or loadxxx() to use values that come from the device.

Definition at line 3412 of file yocto_api.cpp.

string YFunction::describe ( void  )

Returns a short text that describes unambiguously the instance of the function in the form TYPE(NAME)=SERIAL&#46;FUNCTIONID. More precisely, TYPE is the type of the function, NAME it the name used for the first access to the function, SERIAL is the serial number of the module if the module is connected or "unresolved", and FUNCTIONID is the hardware identifier of the function if the module is connected. For example, this method returns Relay(MyCustomName.relay1)=RELAYLO1-123456.relay1 if the module is already connected or Relay(BadCustomeName.relay1)=unresolved if the module has not yet been connected. This method does not trigger any USB or TCP transaction and can therefore be used in a debugger.

Returns
a string that describes the function (ex: Relay(MyCustomName.relay1)=RELAYLO1-123456.relay1)

static YFunction* YFunction::Find ( string  func)
inlinestatic

Definition at line 1792 of file yocto_api.h.

YFunction * YFunction::FindFunction ( string  func)
static

Retrieves a function for a given identifier. The identifier can be specified using several formats:

  • FunctionLogicalName
  • ModuleSerialNumber.FunctionIdentifier
  • ModuleSerialNumber.FunctionLogicalName
  • ModuleLogicalName.FunctionIdentifier
  • ModuleLogicalName.FunctionLogicalName

This function does not require that the function is online at the time it is invoked. The returned object is nevertheless valid. Use the method YFunction.isOnline() to test if the function is indeed online at a given time. In case of ambiguity when looking for a function by logical name, no error is notified: the first instance found is returned. The search is performed first by hardware name, then by logical name.

If a call to this object's is_online() method returns FALSE although you are certain that the matching device is plugged, make sure that you did call registerHub() at application initialization time.

Parameters
func: a string that uniquely characterizes the function
Returns
a YFunction object allowing you to drive the function.

a string corresponding to a short string representing the current state of the function

On failure, throws an exception or returns Y_ADVERTISEDVALUE_INVALID.

Definition at line 2447 of file yocto_api.cpp.

string YFunction::get_errorMessage ( void  )

Returns the error message of the latest error with the function. This method is mostly useful when using the Yoctopuce library with exceptions disabled.

Returns
a string corresponding to the latest error message that occured while using the function object

Definition at line 3277 of file yocto_api.cpp.

YRETCODE YFunction::get_errorType ( void  )

Returns
a number corresponding to the code of the latest error that occurred while using the function object

Definition at line 3264 of file yocto_api.cpp.

string YFunction::get_friendlyName ( void  )
virtual

Returns a global identifier of the function in the format MODULE_NAME&#46;FUNCTION_NAME. The returned string uses the logical names of the module and of the function if they are defined, otherwise the serial number of the module and the hardware identifier of the function (for example: MyCustomName.relay1)

Returns
a string that uniquely identifies the function using logical names (ex: MyCustomName.relay1)

On failure, throws an exception or returns Y_FRIENDLYNAME_INVALID.

Reimplemented in YModule.

Definition at line 3151 of file yocto_api.cpp.

YFUN_DESCR YFunction::get_functionDescriptor ( void  )

Returns a unique identifier of type YFUN_DESCR corresponding to the function. This identifier can be used to test if two instances of YFunction reference the same physical function on the same physical device.

Returns
an identifier of type YFUN_DESCR.

If the function has never been contacted, the returned value is Y_FUNCTIONDESCRIPTOR_INVALID.

Definition at line 3503 of file yocto_api.cpp.

string YFunction::get_functionId ( void  )

Returns the hardware identifier of the function, without reference to the module. For example relay1

Returns
a string that identifies the function (ex: relay1)

On failure, throws an exception or returns Y_FUNCTIONID_INVALID.

Definition at line 3229 of file yocto_api.cpp.

string YFunction::get_hardwareId ( void  )

Returns the unique hardware identifier of the function in the form SERIAL.FUNCTIONID. The unique hardware identifier is composed of the device serial number and of the hardware identifier of the function (for example RELAYLO1-123456.relay1).

Returns
a string that uniquely identifies the function (ex: RELAYLO1-123456.relay1)

On failure, throws an exception or returns Y_HARDWAREID_INVALID.

Definition at line 3194 of file yocto_api.cpp.

string YFunction::get_hubSerial ( )
string YFunction::get_logicalName ( void  )

Returns the logical name of the function.

Returns
a string corresponding to the logical name of the function

On failure, throws an exception or returns Y_LOGICALNAME_INVALID.

Definition at line 2386 of file yocto_api.cpp.

YModule * YFunction::get_module ( void  )

Gets the YModule object for the device on which the function is located. If the function cannot be located on any module, the returned instance of YModule is not shown as on-line.

Returns
an instance of YModule

Definition at line 3440 of file yocto_api.cpp.

void * YFunction::get_userData ( void  )

Returns the value of the userData attribute, as previously stored using method set_userData. This attribute is never touched directly by the API, and is at disposal of the caller to store a context.

Returns
the object stored previously by the caller.

Definition at line 3469 of file yocto_api.cpp.

bool YFunction::isOnline ( void  )

Checks if the function is currently reachable, without raising any error. If there is a cached value for the function in cache, that has not yet expired, the device is considered reachable. No exception is raised if there is an error while trying to contact the device hosting the function.

Returns
true if the function can be reached, and false otherwise

Definition at line 3291 of file yocto_api.cpp.

YRETCODE YFunction::load ( int  msValidity)

Preloads the function cache with a specified validity duration. By default, whenever accessing a device, all function attributes are kept in cache for the standard duration (5 ms). This method can be used to temporarily mark the cache as valid for a longer period, in order to reduce network traffic for instance.

Parameters
msValidity: an integer corresponding to the validity attributed to the loaded function parameters, in milliseconds
Returns
YAPI_SUCCESS when the call succeeds.

On failure, throws an exception or returns a negative error code.

Definition at line 3391 of file yocto_api.cpp.

string YFunction::loadAttribute ( string  attrName)
virtual

Returns the current value of a single function attribute, as a text string, as quickly as possible but without using the cached value.

Parameters
attrName: the name of the requested attribute
Returns
a string with the value of the the attribute

On failure, throws an exception or returns an empty string.

int YFunction::muteValueCallbacks ( void  )
virtual

Disables the propagation of every new advertised value to the parent hub. You can use this function to save bandwidth and CPU on computers with limited resources, or to prevent unwanted invocations of the HTTP callback. Remember to call the saveToFlash() method of the module if the modification must be kept.

Returns
YAPI_SUCCESS when the call succeeds.

On failure, throws an exception or returns a negative error code.

comment from .yc definition

Definition at line 2627 of file yocto_api.cpp.

int YFunction::registerValueCallback ( YFunctionValueCallback  callback)
virtual

Registers the callback function that is invoked on every change of advertised value. The callback is invoked only during the execution of ySleep or yHandleEvents. This provides control over the time when the callback is triggered. For good responsiveness, remember to call one of these two functions periodically. To unregister a callback, pass a NULL pointer as argument.

Parameters
callback: the callback function to call, or a NULL pointer. The callback function should take two arguments: the function object of which the value has changed, and the character string describing the new advertised value.

Definition at line 2544 of file yocto_api.cpp.

int YFunction::set_advertisedValue ( const string &  newval)

Definition at line 2469 of file yocto_api.cpp.

int YFunction::set_logicalName ( const string &  newval)

Changes the logical name of the function. You can use yCheckLogicalName() prior to this call to make sure that your parameter is valid. Remember to call the saveToFlash() method of the module if the modification must be kept.

Parameters
newval: a string corresponding to the logical name of the function
Returns
YAPI_SUCCESS if the call succeeds.

On failure, throws an exception or returns a negative error code.

Definition at line 2420 of file yocto_api.cpp.

void YFunction::set_userData ( void *  data)

Stores a user context provided as argument in the userData attribute of the function. This attribute is never touched by the API, and is at disposal of the caller to store a context.

Parameters
data: any kind of object to be stored
