public class BooleanFormat extends java.text.Format
Formatter for boolean numbers.The boolean formatter pattern consists of at least a pair of values separated by '|'. Several pairs can be specified separated by commas.
When several pairs are specified, only the first one is used for output.
An option "[strict]" can prefix the pattern MUST match either false or true. Default behavior is to return FALSE when not matching any of the pair values. When not in strict mode, the strings are all trimmed before comparing with case insensitive string compare.

Method Detail
format
public java.lang.StringBuffer format(java.lang.Object obj, java.lang.StringBuffer toAppendTo, java.text.FieldPosition pos)
Formats an object and appends the resulting text to a given string buffer.If the
pos
argument identifies a field used by the format, then its indices are set to the beginning and end of the first such field encountered.- Specified by:
format
in classjava.text.Format
- Parameters:
obj
- The object to format.toAppendTo
- To where the text is to be appendedpos
- AFieldPosition
identifying a field in the formatted text.- Returns:
- The string buffer passed in as
toAppendTo
, with formatted text appended. - Throws:
java.lang.NullPointerException
- iftoAppendTo
orpos
is null.java.lang.IllegalArgumentException
- if the Format cannot format the given object.
parseObject
public java.lang.Object parseObject(java.lang.String source, java.text.ParsePosition pos)
Parses text from a string to produce an object.The method attempts to parse text starting at the index given by
pos
.If parsing succeeds, then the index of
pos
is updated to the index after the last character used (parsing does not necessarily use all characters up to the end of the string), and the parsed object is returned. The updatedpos
can be used to indicate the starting point for the next call to this method. If an error occurs, then the index ofpos
is not changed, the error index ofpos
is set to the index of the character where the error occurred, and null is returned.- Specified by:
parseObject
in classjava.text.Format
- Parameters:
source
- AString
, part of which should be parsed.pos
- AParsePosition
object with index and error index information as described above.- Returns:
- An
Object
parsed from the string. In case of error, returns null.
parseObject
public java.lang.Object parseObject(java.lang.String source) throws java.text.ParseException
Parses text from the beginning of the given string to produce an object. The method may not use the entire text of the given string.- Overrides:
parseObject
in classjava.text.Format
- Parameters:
source
- AString
whose beginning should be parsed.- Returns:
- An
Object
parsed from the string. - Throws:
java.text.ParseException
- if the beginning of the specified string cannot be parsed.
