ParsePosition (Java SE 17 & JDK 17)
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.

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
-
hashCode
public int hashCode()
Returns a hash code for this ParsePosition.
-
toString
Return a string representation of this ParsePosition.
