Field Detail

base

public int base

minWidth

public int minWidth

Minimal width of the result, includiing sign, commas, etc. However, if the MIN_DIGITS flag is given, it's the minimum number of digits instead. This is used for printf-style "precision".

padChar

public int padChar

The padding characters, by default ' '.

commaChar

public int commaChar

commaInterval

public int commaInterval

flags

public int flags

SHOW_GROUPS

public static final int SHOW_GROUPS

Do groups (for example thousands, using commas).

Method Detail

format

public int format(java.lang.Object[] args,
                  int start,
                  java.io.Writer dst,
                  java.text.FieldPosition fpos)
           throws java.io.IOException

Description copied from class: ReportFormat

Format an array of arguments, and write out the result.

Specified by:

format in class ReportFormat

Parameters:

args - the objects to be formatted

start - the index (in args) of the argument to start with

dst - where to write the result

Returns:

an integer result(resultCode, nextArg), where nextArg is the index following the last argument processed, and code is a result code (normally 0, or negative if early termintation)

Throws:

java.io.IOException

format

           throws java.io.IOException

Overrides:

format in class ReportFormat

Throws:

java.io.IOException
