ParsePosition
extends Object
| 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 |
int: initial index |
Public methods
equals
public boolean equals (Object obj)
Overrides equals
| Parameters | |
|---|---|
obj |
Object: the reference object with which to compare. |
| Returns | |
|---|---|
boolean |
true if this object is the same as the obj
argument; false otherwise. |
getErrorIndex
public int getErrorIndex ()
Retrieve the index at which an error occurred, or -1 if the error index has not been set.
| Returns | |
|---|---|
int |
the index at which an error occurred |
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 | |
|---|---|
int |
the current parse position |
hashCode
public int hashCode ()
Returns a hash code for this ParsePosition.
| Returns | |
|---|---|
int |
a hash code value for this object |
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 |
int: the index at which an error occurred |
setIndex
public void setIndex (int index)
Set the current parse position.
| Parameters | |
|---|---|
index |
int: the current parse position |
