public class FormattableUtils extends Object
Provides utilities for working with the Formattable interface.
The Formattable interface provides basic control over formatting
when using a Formatter. It is primarily concerned with numeric precision
and padding, and is not designed to allow generalised alternate formats.

| Modifier and Type | Method and Description |
|---|---|
static Formatter |
append(CharSequence seq,
Formatter formatter,
int flags,
int width,
int precision)
Handles the common
Formattable operations of truncate-pad-append,
with no ellipsis on precision overflow, and padding width underflow with
spaces. |
static Formatter |
append(CharSequence seq,
Formatter formatter,
int flags,
int width,
int precision,
char padChar)
Handles the common
Formattable operations of truncate-pad-append,
with no ellipsis on precision overflow. |
static Formatter |
append(CharSequence seq,
Formatter formatter,
int flags,
int width,
int precision,
char padChar,
CharSequence ellipsis)
Handles the common
Formattable operations of truncate-pad-append. |
static Formatter |
append(CharSequence seq,
Formatter formatter,
int flags,
int width,
int precision,
CharSequence ellipsis)
Handles the common
Formattable operations of truncate-pad-append,

static String |
toString(Formattable formattable)
Get the default formatted representation of the specified
Formattable. |
public FormattableUtils()
FormattableUtils instances should NOT be constructed in
standard programming. Instead, the methods of the class should be invoked
statically.
This constructor is public to permit tools that require a JavaBean instance to operate.
