Detailed Description

Vector objects are used to store 1-dimensional data.

Remarks:

Using vectors is very similar to using 1-dimensional arrays, except that the size can vary at runtime. Memory allocation is handled internally.

• To create a vector, use its constructor.
• To fill a vector with values, first empty it, using the eVision.EVector.Empty member, and then add elements one at time at the tail by calling the eVision.EBWHistogramVector.AddElement member.
• To access a vector element, either for reading or writing, use the [] operator.
• To inquire for the current number of elements, use member eVision.EVector.NumElements.

Constructor & Destructor Documentation

__init__() [1/3]

None eVision.EBWHistogramVector.__init__

(

self

)

Constructs a vector.

__init__() [2/3]

None eVision.EBWHistogramVector.__init__	(		self,
		eVision.EBWHistogramVector	other )

Constructs a vector.

Parameters

other

eVision.EBWHistogramVector object to be copied

__init__() [3/3]

None eVision.EBWHistogramVector.__init__	(		self,
		int	maxNumberOfElements )
