Class ParsePosition
java.lang.Object
java.text.ParsePosition
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
