Detailed Description

Helper class for NumericRange handling.

The numeric range provides a way to identify a subset of a single or multidimensional array of data. The numeric range is provided as a string with a defined syntax for different constructs like single index into an array, a range of the array or a subset of a multidimensional array.

BNF for NumericRange:
<numeric-range> ::= dimension [',' dimension]
dimension ::= index [':' index]
index ::= digit [digit]
digit ::= '0' | '1' | '2' | '3' | '4' | '5' | '6' | '7' | '8' | '9'

Constructor & Destructor Documentation

UaNumericRange::UaNumericRange

(

)

Constructs a numeric range object with initial value.

No numeric range is set.

Member Function Documentation

bool UaNumericRange::isValid

(

)

const

Test the numeric range for validity.

• The number of dimensions must be at least 1
• All dimensions have to be either of type INDEX or RANGE
• For RANGE, firstIndex has to be smaller than secondIndex
