Class java.text.FieldPosition

java.lang.Object

   +----java.text.FieldPosition

public class FieldPosition
extends Object
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).
