FeatVal


Unit: SDL_dstruct
Class: TFeatureMatrix
Declaration: property FeatVal[fix, obj: integer]: string;

The array property FeatVal provides access to the cells [fix,obj] of the feature matrix, given that the referenced cell is of type string. The parameter fix may assume values between 1 and NFeatures, the parameter obj may assume values between 1 and NObjects. Parameter values outside the valid range will be ignored when writing to the cell (resulting in no action at all), or a zero value will be returned when reading the FeatVal property.

Accessing cells within the valid range might generate an exception if the accessed cell is of a type other than string:

Data Type Read Write
fkUndefined exception exception
fkInteger OK exception if the string value is not a valid integer
fkDouble OK exception if the string value is not a valid floating point number
fkString OK OK
fkTriState OK exception if the string value is not a valid tri-state value
