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::ParsePosition () [inline]
|
Default constructor, the index starts with 0 as default.
ParsePosition::ParsePosition (UTextOffset newIndex) [inline]
|
Create a new ParsePosition with the given initial index.
newIndex | the new text offset. |
ParsePosition::ParsePosition (const ParsePosition & copy) [inline]
|
Copy constructor.
copy | the object to be copied from. |
ParsePosition::~ParsePosition () [inline]
|
Destructor.
ParsePosition & ParsePosition::operator= (const ParsePosition & copy) [inline]
|
Assignment operator.
bool_t ParsePosition::operator== (const ParsePosition & copy) const [inline]
|
Equality operator.
bool_t ParsePosition::operator!= (const ParsePosition & copy) const [inline]
|
Equality operator.
UTextOffset ParsePosition::getIndex (void) const [inline]
|
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.
void ParsePosition::setIndex (UTextOffset idx) [inline]
|
Set the current parse position.
index | the new index. |
void ParsePosition::setErrorIndex (UTextOffset ei) [inline]
|
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.
UTextOffset ParsePosition::getErrorIndex (void) const [inline]
|
Retrieve the index at which an error occurred, or -1 if the error index has not been set.
