Class ParsePosition

java.lang.Object
java.text.ParsePosition
public class ParsePosition extends Object
ParsePosition is a simple class used by Format and its subclasses to keep track of the current position during parsing. The parseObject method in the various Format classes requires a ParsePosition object as an argument.

By design, as you parse through a string with different formats, you can use the same ParsePosition, since the index parameter records the current position.

    • ParsePosition

      public ParsePosition(int index)
      Create a new ParsePosition with the given initial index.
      Parameters:
      index - initial index

  • Method Details

    • getIndex

      public int getIndex()
      Retrieve the current parse position. On input to a parse method, this is the index of the character at which parsing will begin; on output, it is the index of the character following the last character parsed.
      Returns:
      the current parse position

    • setIndex

      public void setIndex(int index)
      Set the current parse position.
      Parameters:
      index - the current parse position

    • setErrorIndex

      public void setErrorIndex(int ei)
      Set the index at which a parse error occurred. Formatters should set this before returning an error code from their parseObject method. The default value is -1 if this is not set.
      Parameters:
      ei - the index at which an error occurred
      Since:
      1.2

    • getErrorIndex

      public int getErrorIndex()
      Retrieve the index at which an error occurred, or -1 if the error index has not been set.
      Returns:
      the index at which an error occurred
      Since:
      1.2

    • equals

      public boolean equals(Object obj)
      Overrides equals
      Overrides:
      equals in class Object
      Parameters:
      obj - the reference object with which to compare.
      Returns:
      true if this object is the same as the obj argument; false otherwise.

    • hashCode

      public int hashCode()
      Returns a hash code for this ParsePosition.
      Overrides:
      hashCode in class Object
      Returns:
      a hash code value for this object
