        public ValidationListDataToEncrypt()
        Constructs a ValidationListDataToEncrypt.

        public ValidationListDataToEncrypt(byte[] buffer,
                                   int offset)
        Constructs a ValidationListDataToEncrypt from a structure stored as IBM i bytes.

        The offset indicates the starting position of the structure in the given buffer.

        buffer - byte[]
        offset - int

        public ValidationListDataToEncrypt(int ccsid,
                                   byte[] bytes)
        Constructs a ValidationListDataToEncrypt from the specified IBM i bytes which are encoded in the given ccsid.

                                   AS400 as400)
        Constructs a ValidationListDataToEncrypt from the given string.

        The translated bytes are derived by converting the string to IBM i bytes using the given ccsid. The as400 is required to perform the conversion from text to bytes. A ccsid of 0 indicates to use the ccsid of the current user.

    • Method Detail

      • getWriteNullDataLength

        protected int getWriteNullDataLength()
        Returns the length to be specified in the written IBM i byte structure if the assigned data is null.

        Typically this value is 0. However, there are some cases where other values must be returned to maintain proper behavior. For example, when changing an entry a structure must be specified for the data to encrypt, even if the encrypted data should not be changed. However, if the data length in the structure is set to 0 instead of -1, the existing encrypted data is wiped out. This is undesirable since we don't always want the encrypted data changed. We might want to modify the unencrypted data (i.e. user statistics) while leaving the encrypted data (i.e. user password) unchanged.
