    Table of contents

    Description of the method

     

    Description: This method returns the character located at the String's specified index. The string indexes start from zero.
    Available for: string
    Parameters: int
    Return type: char

    Example

     

    Context: TransactionType1
    OCL: self.Id.charAt(1) = "A"
    Description: Example rule expects the position 1 (the second character in string) to contain "A".

     

    The XML snippets below would pass this check.

    <Id>aAa</Id>

    <Id>a</Id>

     

    It is worth noting that when the character does not exist in the defined position, expression is not ran.

    The other snippet below however would not pass this check.

    <Id>AaA</Id>
