Method Details

compNumeric

public static PictureUtils.CompNumeric compNumeric(String pic)

Computational numerics have picture clauses like 9(4) or S9(5)V99.

Parameters:

pic - the cobol picture clause

Aphanumerics have picture clauses like X(4) or +9(5).99.

All characters contribute to the length of the alphanumeric apart from the V character which stands for a virtual decimal delimiter.

Parameters:

pic - the cobol picture clause

Returns:

the alphanumeric properties

isCompNumeric

public static boolean isCompNumeric(String pic)

Is this picture that of a computational numeric.

Parameters:

pic - the picture clause

Returns:

true if this picture corresponds to a computational numeric

isAlphaNumeric

public static boolean isAlphaNumeric(String pic)

Is this picture that of an alphanumeric.

Parameters:

pic - the picture clause

Returns:

true if this picture corresponds to an alphanumeric

digitCount

public static int digitCount(String numberPart)

Calculate the number of digits given a numeric description like 9999 or 9(4)

Parameters:

numberPart - a numeric picture part

Returns:

number of digits

charCount

public static int charCount(String alphaPart)

Calculate the number of characters given an alphanumeric like XXXX or X(4)

Parameters:

alphaPart - the picture part

Returns:

the number of characters
