TSignalWrite Members

The following tables list the members exposed by TSignalWrite.

	Name	Description
	OnAfterUpdateEvent	The event is triggered after the call to the Update method.
	OnBeforeUpdateEvent	The event is triggered just before the call to the Update method.
	OnDisplayUpdateEvent	The event is triggered after the OnAfterUpdate event. Use this event to update any associated charts or graphs or result tables.
	OnGetInputEvent	If the Input property is not assigned, the component will call OnGetInput.
	OnNotifyUpdateEvent	The event is called after a call to InternalUpdate, OnAfterUpdate and OnDisplayUpdate from within the Update method.
	OnParameterUpdateEvent	The event is triggered when ParamUpdate method is called. The ParamUpdate method is usually called by component editors when a value was changed by the user and the editor was "Live".

	TSignalWrite	This is the overview for the TSignalWrite constructor overload.
	Update	Request recalculation of the data and place the result in Self.
	UpdateNotify	Call this method only, if SuspendNotifyUpdate is True.

Public Properties

	Name	Description
	Active	Set active to false to suppress the propagation of the Pull request and the subsequent call to the Update method.

	BandwidthH	Returns the upper bandwidth edge of the signal.
	BandwidthL	Returns the lower bandwidth edge of the signal.
	ChannelCount	Get or set the number of channels multiplexed in the data property.
	Complex	Set this property to true, to request computation using complex numbers.
	Continuous	If True, the component will pass on the udpate request to the connected component.
	Data	Stores the result of the processing.
	Dt	Time between two consecutive samples.
	FileFormat	Defines the format of the file, if AutoFileFormat property is False.
	FileName	Defines the file name to be read from or written to.
	FloatPrecision	Set this property to request computation in 32bit/64bit precision with real/complex numbers.
	FloatPrecisionLock	Set this property to true to lock changes to FloatPrecision property.
	HzRes	Frequency resolution obtained, if an FFT algorithm would be run on the data.
	ImFormat	Number format definition for text file formats.
	Input	Source data to be written to the file.
	IsDouble	Set this property to false, to request computation in 32bit floating point precision, 64bit, if true.
	ItemNumber	Number to label the object when it is an item in the List.
	Length	Get or set the length of the signal in samples.
	Marks	Stores the time stamps and amplitude of selected samples.
	MaxAmplt	Stores the maximum amplitude of the signal found by the MinMax method.
	MaxX	Use the MaxX property to store the time stamp (in seconds) of the right most sample.
	MinAmplt	Stores the minimum amplitude of the signal found by the MinMax method.
	MinX	Use the MinX property to store the time stamp of the left-most sample.
	OnAfterUpdate	The event is triggered after the call to the Update method.
