virtual void	touch (FieldSensor::Strength strength=FieldSensor::CHANGED)
	Notifies all connected fields and field sensors.
void	enableNotifications (bool flag)
	Enables or disables notification of attached fields and field sensors when the field value is set or notified (by notifyAttachments() or set*Value() -methods), depending on the parameter flag.
bool	areNotificationsEnabled ()
	Returns whether the notification mechanism for this field (e.g., when field values are set) is enabled (see enableNotifications(bool) ).

Additional Inherited Members
Static Public Member Functions inherited from ml::Field
static void	enableNotificationsGlobally (bool flag)
	Enables or disables globally the notification mechanism for all fields and field sensors when field values are set or notified (by notifyAttachments() or set*Value() methods), depending on the parameter flag.
static bool	areNotificationsEnabledGlobally ()
	Returns whether the notification mechanism for all fields (e.g., when field values are set) is enabled (see enableNotificationsGlobally(bool) ) Usually it is false(=0) within all calls of Module::calc* methods to avoid that field changes within these methods recursively start the calculation process of the ML.
static MLint &	enableNotificationsCounterState ()
	Provides read/write access to the current counter state (see enableNotificationsGlobally(bool) ).
Protected Member Functions inherited from ml::Field

void	detachSourceField (Field *field)
	Removes a source field from this instance. If not found then this call does nothing.

Detailed Description

Field to encapsulate a pointer to an input connector which represents a module input.

Definition at line 749 of file mlFields.h.

Constructor & Destructor Documentation

InputConnectorField() [1/2]

ml::InputConnectorField::InputConnectorField

(

)

Implements the runtime type system interface for this class.

Default constructor, do not use it.

InputConnectorField() [2/2]

ml::InputConnectorField::InputConnectorField	(	const std::string &	name,
		Module *	module,
		MLint	inputImageIndex )

Constructor, creates a field with a name to manage an InputConnector on the Module module at index inputImageIndex.

Note that the field always stores a pointer to the connector as field value.

~InputConnectorField()

ml::InputConnectorField::~InputConnectorField ( )

override

Destroys the field.

Member Function Documentation

getInputConnectorValue()

InputConnector & ml::InputConnectorField::getInputConnectorValue

(

)

const

Returns a reference to the InputConnector.

getStringValue()

std::string ml::InputConnectorField::getStringValue ( ) const

overridevirtual

Returns a reference to InputConnector as a C-string (InputConnector does not have a value).

Implements ml::Field.

isValidValue()

MLint ml::InputConnectorField::isValidValue ( )

overridevirtual

Returns 1 if connector field contains a valid connector pointer.

Reimplemented from ml::Field.

setStringValue()

void ml::InputConnectorField::setStringValue ( const std::string & )

overridevirtual

Only calls touch() to propagate notifications.

It implicitly clears the cache of the input connector field.

Implements ml::Field.
