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() [1/3]

icu::ParsePosition::ParsePosition ( )

inline

Default constructor, the index starts with 0 as default.

Stable:

ICU 2.0

Definition at line 58 of file parsepos.h.

ParsePosition() [2/3]

icu::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 69 of file parsepos.h.

ParsePosition() [3/3]

icu::ParsePosition::ParsePosition ( const ParsePosition &  copy )

inline

Copy constructor.

Parameters

copy	the object to be copied from.

Stable:

ICU 2.0

Definition at line 80 of file parsepos.h.

~ParsePosition()

virtual icu::ParsePosition::~ParsePosition ( )

virtual

Destructor.

Stable:

ICU 2.0

Member Function Documentation

clone()

ParsePosition * icu::ParsePosition::clone

(

)

const

Clone this object.

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

Returns

a clone of this object

getDynamicClassID

Stable:

ICU 2.8

getDynamicClassID()

virtual UClassID icu::ParsePosition::getDynamicClassID ( ) const

overridevirtual

ICU "poor man's RTTI", returns a UClassID for the actual class.

Stable:

ICU 2.2

Reimplemented from icu::UObject.

getErrorIndex()

int32_t icu::ParsePosition::getErrorIndex ( ) 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 223 of file parsepos.h.

getIndex()

int32_t icu::ParsePosition::getIndex ( ) 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 211 of file parsepos.h.

getStaticClassID()

static UClassID icu::ParsePosition::getStaticClassID ( )

static

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

Stable:

ICU 2.2

operator!=()

bool icu::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 205 of file parsepos.h.

References icu::operator==().

operator=()

ParsePosition & icu::ParsePosition::operator= ( const ParsePosition &  copy )

inline

Assignment operator.

Stable:

ICU 2.0

Definition at line 188 of file parsepos.h.

operator==()

bool icu::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 196 of file parsepos.h.

setErrorIndex()

void icu::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 229 of file parsepos.h.

setIndex()

void icu::ParsePosition::setIndex ( int32_t  index )

inline

Set the current parse position.

Parameters

index

the new index.

Stable:

ICU 2.0

Definition at line 217 of file parsepos.h.
