Class ParsePosition

java.lang.Object
  extended by 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.

Constructor Detail

ParsePosition

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

Method Detail

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.


setIndex

public void setIndex(int index)
Set 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.

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.

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.

Object.hashCode(), Hashtable

hashCode

public int hashCode()
Returns a hash code for this ParsePosition.

Overrides:
hashCode in class Object
Returns:
a hash code value for this object
See Also:
Object.equals(java.lang.Object), Hashtable

toString

public String toString()
Return a string representation of this ParsePosition.

Overrides:
toString in class Object
Returns:
a string representation of this object
