FieldPosition
is a simple class used by Format
and its subclasses to identify fields in formatted output. Fields are
identified by constants, whose names typically end with _FIELD
,
defined in the various subclasses of Format
. See
ERA_FIELD
and its friends in DateFormat
for
an example.
FieldPosition
keeps track of the position of the
field within the formatted output with two indices: the index
of the first character of the field and the index of the last
character of the field.
One version of the format
method in the various
Format
classes requires a FieldPosition
object as an argument. You use this format
method
to perform partial formatting or to get information about the
formatted output (such as the position of a field).
