Detailed Description

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.

Constructor & Destructor Documentation

ParsePosition::ParsePosition (   )  [inline]

Default constructor, the index starts with 0 as default. Stable: ICU 2.0 Definition at line 54 of file parsepos.h.

ParsePosition::ParsePosition (  int32_t  newIndex  )  [inline]

Create a new ParsePosition with the given initial index. Parameters: newIndex  the new text offset. Stable: ICU 2.0 Definition at line 66 of file parsepos.h.

ParsePosition::ParsePosition (  const ParsePosition &  copy  )  [inline]

Copy constructor. Parameters: copy  the object to be copied from. Stable: ICU 2.0 Definition at line 78 of file parsepos.h.

virtual ParsePosition::~ParsePosition (   )  [virtual]

Destructor. Stable: ICU 2.0

Member Function Documentation

ParsePosition* ParsePosition::clone (   )  const

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. Returns: a clone of this object See also: getDynamicClassID Stable: ICU 2.8

virtual UClassID ParsePosition::getDynamicClassID (   )  const [virtual]

ICU "poor man's RTTI", returns a UClassID for the actual class. Stable: ICU 2.2 Implements UObject.

int32_t ParsePosition::getErrorIndex (  void   )  const [inline]

Retrieve the index at which an error occurred, or -1 if the error index has not been set. Stable: ICU 2.0 Definition at line 232 of file parsepos.h.

int32_t 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. Returns: the current index. Stable: ICU 2.0 Definition at line 220 of file parsepos.h.

UClassID ParsePosition::getStaticClassID (   )  [static]

ICU "poor man's RTTI", returns a UClassID for this class. Stable: ICU 2.2

UBool ParsePosition::operator!= (  const ParsePosition &  that  )  const [inline]

Equality operator. Returns: TRUE if the two parse positions are not equal, FALSE otherwise. Stable: ICU 2.0 Definition at line 214 of file parsepos.h.

ParsePosition & ParsePosition::operator= (  const ParsePosition &  copy  )  [inline]

Assignment operator. Stable: ICU 2.0 Definition at line 197 of file parsepos.h.

UBool ParsePosition::operator== (  const ParsePosition &  that  )  const [inline]

Equality operator. Returns: TRUE if the two parse positions are equal, FALSE otherwise. Stable: ICU 2.0 Definition at line 205 of file parsepos.h.

void ParsePosition::setErrorIndex (  int32_t  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. Stable: ICU 2.0 Definition at line 238 of file parsepos.h.

void ParsePosition::setIndex (  int32_t  index  )  [inline]

Set the current parse position. Parameters: index  the new index. Stable: ICU 2.0 Definition at line 226 of file parsepos.h.
