Constructor Details

MessageFormat

public MessageFormat(String pattern)
Creates a new MessageFormat object with the specified pattern
Parameters:
pattern - The Pattern

MessageFormat

public MessageFormat(String pattern,
                     Locale locale)
Creates a new MessageFormat object with the specified pattern
Parameters:
pattern - The Pattern
locale - The Locale to use
Since:
1.4

Method Details

applyPattern

public void applyPattern(String newPattern)
Applies the specified pattern to this MessageFormat.
Parameters:
newPattern - The Pattern

clone

public Object clone()
Overrides Format.clone()
Overrides:
clone in interface Format

equals

public boolean equals(Object obj)
Overrides Format.equals(Object obj)
Overrides:
equals in interface Object

format

public final StringBuffer format(arguments[] ,
                                 StringBuffer appendBuf,
                                 FieldPosition fp)
Returns the pattern with the formatted objects.
Parameters:
appendBuf - The StringBuffer where the text is appened.
fp - A FieldPosition object (it is ignored).

format

public final StringBuffer format(Object objectArray,
                                 StringBuffer appendBuf,
                                 FieldPosition fpos)
Returns the pattern with the formatted objects. The first argument must be a array of Objects. This is equivalent to format((Object[]) objectArray, appendBuf, fpos)
Overrides:
format in interface Format
Parameters:
objectArray - The object array to be formatted.
appendBuf - The StringBuffer where the text is appened.
fpos - A FieldPosition object (it is ignored).

format

public static String format(String pattern,
                            java.lang.Object... arguments)
A convinience method to format patterns.
Parameters:
pattern - The pattern used when formatting.
arguments - The array containing the objects to be formatted.

formatToCharacterIterator

public AttributedCharacterIterator formatToCharacterIterator(Object arguments)
A convinience method to format patterns.
Overrides:
formatToCharacterIterator in interface Format
Parameters:
arguments - The array containing the objects to be formatted.

getFormats

public Format[] getFormats()
Returns an array with the Formats for the arguments.

getFormatsByArgumentIndex

public Format[] getFormatsByArgumentIndex()
Return the formatters used sorted by argument index. It uses the internal table to fill in this array: if a format has been set using setFormat or setFormatByArgumentIndex then it returns it at the right index. If not it uses the detected formatters during a format call. If nothing is known about that argument index it just puts null at that position. To get useful informations you may have to call format at least once.
Returns:
an array of formatters sorted by argument index.

getLocale

public Locale getLocale()
Returns the locale.

hashCode

public int hashCode()
Overrides Format.hashCode()
Overrides:
hashCode in interface Object

parse

public Object[] parse(String sourceStr)
            throws ParseException

parse

public Object[] parse(String sourceStr,
                      ParsePosition pos)
Parse a string sourceStr against the pattern specified to the MessageFormat constructor.
Parameters:
sourceStr - the string to be parsed.
pos - the current parse position (and eventually the error position).
Returns:
the array of parsed objects sorted according to their argument number in the pattern.

parseObject

public Object parseObject(String sourceStr,
                          ParsePosition pos)
This method parses a String and converts the parsed contents into an Object.
Overrides:
parseObject in interface Format
Parameters:
pos - The starting parse index on input, the ending parse index on output.
Returns:
The parsed Object, or null in case of error.

setFormat

public void setFormat(int variableNum,
                      Format newFormat)
Sets the format for the argument at an specified index.
Parameters:
variableNum - The index.
newFormat - The Format object.

setFormatByArgumentIndex

public void setFormatByArgumentIndex(int argumentIndex,
                                     Format newFormat)
Set the format to used using the argument index number.
Parameters:
argumentIndex - the argument index.
newFormat - the format to use for this argument.

setFormats

public void setFormats(Format[] newFormats)
Sets the formats for the arguments.
Parameters:
newFormats - An array of Format objects.

setFormatsByArgumentIndex

public void setFormatsByArgumentIndex(Format[] newFormats)
Set the format for argument using a specified array of formatters which is sorted according to the argument index. If the number of elements in the array is fewer than the number of arguments only the arguments specified by the array are touched.
Parameters:
newFormats - array containing the new formats to set.
Throws:
NullPointerException - if newFormats is null

setLocale

public void setLocale(Locale loc)
Sets the locale.
Parameters:
loc - A Locale

toPattern

public String toPattern()
Returns the pattern.
