Constructor Detail

OraDecimalFormat

public OraDecimalFormat()

Deprecated. As of Oracle Database 10g Release 2 (10.2), replaced by OraDecimalFormat.OraDecimalFormat(String, OraDecimalFormatSymbols)

Constructs an OraDecimalFormat object using the default number format pattern and the default decimal format symbols for the default locale.

OraDecimalFormat

public OraDecimalFormat(String pattern)
                 throws ParseException

Deprecated. As of Oracle Database 10g Release 2 (10.2), replaced by OraDecimalFormat.OraDecimalFormat(String, OraDecimalFormatSymbols)

Constructs an OraDecimalFormat object using the given format pattern and the default decimal format symbols for the default locale.

Parameters:

pattern - the given format pattern, if null, uses the default number format pattern for the default locale and supports SQL TO_CHAR()/TO_NUMBER() implicit conversion.

Throws:

ParseException - if the given pattern is invalid

OraDecimalFormat

public OraDecimalFormat(String pattern,
                        OraDecimalFormatSymbols symbols)
                 throws ParseException

Constructs an OraDecimalFormat object using the given format pattern and the given decimal format symbols.

Parameters:

pattern - the give format pattern, if null, uses the default number format pattern for the default locale and supports SQL TO_CHAR()/TO_NUMBER() implicit conversion.

symbols - the given decimal format symbols

Throws:

ParseException - if the given pattern is invalid

Method Detail

applyPattern

public void applyPattern(String pattern)
                  throws ParseException

Modifies this formatter by using the given format pattern. The given format pattern should be specified as:

  "<positive pattern>[;<negative pattern>]"

This means that a positive format pattern must be present but a negative format pattern is optional. If there is no negative pattern given, the positive pattern with a leading minus sign is used for formatting or parsing negative numbers.

Parameters:

pattern - given format pattern, if null, uses the default number format pattern for the default locale and supports SQL TO_CHAR()/TO_NUMBER() implicit conversion.

Throws:

ParseException - if the given pattern is invalid

format

public StringBuffer format(BigDecimal number,
                           StringBuffer toAppendTo,
                           FieldPosition fieldPosition)

Formats a BigDecimal object into a string. Sets field position if it is needed.

Specified by:

format in class OraNumberFormat

Parameters:

number - the BigDecimal object to be formatted.

toAppendTo - the string buffer to be appended with the formatted string.

fieldPosition - to be used to get offsets of a given field in the returned string buffer. On input, the alignment field of which the offsets are to be returned. On output, the offsets of the alignment field in the returned string buffer.

Returns:

the string buffer appended with a formatted string

format

public StringBuffer format(BigInteger number,
                           StringBuffer toAppendTo,
                           FieldPosition fieldPosition)

Formats a BigInteger object into a string. Sets field position if it is needed.

Specified by:

format in class OraNumberFormat

Parameters:

number - the BigInteger object to be formatted.

toAppendTo - the string buffer to be appended with the formatted string.

fieldPosition - to be used to get offsets of a given field in the returned string buffer. On input, the alignment field of which the offsets are to be returned. On output, the offsets of the alignment field in the returned string buffer.

Returns:

the string buffer appended with a formatted string

format

public StringBuffer format(double number,
                           StringBuffer toAppendTo,
