checkExternalDecimal

public static int checkExternalDecimal(byte[] byteArray,
                                       int offset,
                                       int precision,
                                       int decimalType,
                                       int bytesWithSpaces)

Checks the validity of a External Decimal, returns an integer indicating the status of the External Decimal.

Parameters:

byteArray - source array.

offset - starting offset of the External Decimal.

precision - number of digits to be verified.

decimalType - constant indicating the type of the decimal. Supported values are DecimalData.EBCDIC_SIGN_EMBEDDED_TRAILING, DecimalData.EBCDIC_SIGN_EMBEDDED_LEADING, DecimalData.EBCDIC_SIGN_SEPARATE_TRAILING, DecimalData.EBCDIC_SIGN_SEPARATE_LEADING.

bytesWithSpaces - represents number of left most bytes containing EBCDIC space character if sign is embedded, ignored otherwise.

Returns:

the condition code: 0 if all digit codes and the sign are valid, 1 if the sign is invalid, 2 if at least one digit code is invalid, 3 if sign and at least one digit code is invalid.

Throws:

NullPointerException - if byteArray is null.

ArrayIndexOutOfBoundsException - if an invalid array access occurs.

IllegalArgumentException - if the precision is less than 1.

IllegalArgumentException - if the offset is less than 0.

IllegalArgumentException - if decimalType is invalid.

IllegalArgumentException - if bytesWithSpaces is less than 0 when sign is embedded.
