void	attachField (NotifyField *targetField)
void	attachField (Field *targetField, bool propagateValueOnConnect)

size_t	getNumDestinationFields ()
	Returns the number of destination fields which could receive notifications or value sets.
Field *	getDestinationField (size_t index)
	Returns destination field at index. Returns NULL if index is out of range.
size_t	getNumSourceFields ()
	Returns the number of source fields which could send notifications or value sets.
Field *	getSourceField (size_t index)
	Returns the source field at index. Returns NULL if index is out of range.
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	attachSourceField (Field *field)
	Inserts a field as source field in this instance, i.e., from now on *this might receive values and/or notifications from that field.
void	detachSourceField (Field *field)
	Removes a source field from this instance. If not found then this call does nothing.
void	detachFieldInternal (Field *field)
	Only remove the given field from the destination list.

	Flag which disables the notification process of field (sensors) globally.

Detailed Description

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

Definition at line 694 of file mlFields.h.

Constructor & Destructor Documentation

OutputConnectorField() [1/2]

ml::OutputConnectorField::OutputConnectorField

(

)

Implements the runtime type system interface for this class.

Default constructor, do not use it.

OutputConnectorField() [2/2]

ml::OutputConnectorField::OutputConnectorField	(	const std::string &	name,
		Module *	module,
		MLint	outputImageIndex )

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

~OutputConnectorField()

ml::OutputConnectorField::~OutputConnectorField ( )

override

Destroys the field.

Member Function Documentation

getOutputConnectorValue()

OutputConnector & ml::OutputConnectorField::getOutputConnectorValue

(

)

const

Returns a reference to the OutputConnector.

getStringValue()

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

overridevirtual

Reference to OutputConnector as C-string to return (OutputConnector do not have a value, therefore reference is returned).

Returns the value of the field as a string value. setStringValue must be able to interpret this returned string correctly.

Implements ml::Field.

isValidValue()

MLint ml::OutputConnectorField::isValidValue ( )

overridevirtual

Returns 1 if connector field contains a valid connector pointer.

Reimplemented from ml::Field.

setStringValue()

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

overridevirtual

Only calls touch() to propagate notifications.

It implicitly clears the cache of the output connector field.

Implements ml::Field.

touch()

void ml::OutputConnectorField::touch ( FieldSensor::Strength strength = FieldSensor::CHANGED )

overridevirtual

A notified output image must also clear its PagedImage if it is considered as changed.

So it needs to be overloaded here. Default is that it is considered as FieldSensor::CHANGED.

Reimplemented from ml::Field.
