lengthIsMin

Short summary

This assertion method checks if the current string stringToCheck is length is equal or grater than to minLength

Attention: All strings are handled as null terminated byte/word streams. For UTF-8 is end of the string 16#00 For UTF-16 is end of the string 16#00_00

Attention: The interface IUnicodeAssertions uses ANY_STRING, for this it's not possible to use literals/constants, because for ANY types generates the compiler __SYSTEM.AnyType and __SYSTEM.AnyType contains a pointer

Parameters

Name	Type	Comment	Kind
stringToCheck	ANY_STRING	current string to check	input
minLength	UDINT	lower limit of the length of stringToCheck	input
stringLengthUnit	UnicodeStringLengthUnit	string length units of measurement	input
message	AssertMessage	message if the assertion is false	input
