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.
The ParsePosition class is not suitable for subclassing.

Clone this object. Clones can be used concurrently in multiple threads. If an error occurs, then NULL is returned. The caller must delete the clone.

Retrieve the index at which an error occurred, or -1 if the error index has not been set.

|
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.

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.
