  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.

Field Detail

index

int index

Input: the place you start parsing.
Output: position where the parse stopped. This is designed to be used serially, with each call setting index up for the next one.

errorIndex

int errorIndex

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.

hashCode

public int hashCode()

Returns a hash code for this ParsePosition.

Overrides:

hashCode in class Object

Returns:

a hash code value for this object

toString

public String toString()

Return a string representation of this ParsePosition.

Overrides:

toString in class Object

Returns:

a string representation of this object
