class ParsePosition

Defined at line 52 of file ../../third_party/icu/latest/source/common/unicode/parsepos.h

C++ API: Canonical Iterator

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.

Public Methods

void ParsePosition ()

Default constructor, the index starts with 0 as default.

Defined at line 58 of file ../../third_party/icu/latest/source/common/unicode/parsepos.h

void ParsePosition (int32_t newIndex)

Create a new ParsePosition with the given initial index.

Parameters

newIndex the new text offset. ICU 2.0

void ParsePosition (const ParsePosition & copy)

Copy constructor

Parameters

copy the object to be copied from. ICU 2.0

Defined at line 80 of file ../../third_party/icu/latest/source/common/unicode/parsepos.h

void ~ParsePosition ()

Destructor

ICU 2.0

ParsePosition & operator= (const ParsePosition & copy)

Assignment operator

bool operator== (const ParsePosition & that)

Equality operator.

Returns

true if the two parse positions are equal, false otherwise.

ICU 2.0

Defined at line 195 of file ../../third_party/icu/latest/source/common/unicode/parsepos.h

bool operator!= (const ParsePosition & that)

Equality operator.

Returns

true if the two parse positions are not equal, false otherwise.

ParsePosition * clone ()

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

int32_t 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.

Returns

the current index.

void setIndex (int32_t index)

Set the current parse position.

Parameters

index the new index. ICU 2.0

Defined at line 216 of file ../../third_party/icu/latest/source/common/unicode/parsepos.h

void setErrorIndex (int32_t 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.

ICU 2.0

Defined at line 228 of file ../../third_party/icu/latest/source/common/unicode/parsepos.h

int32_t getErrorIndex ()

Retrieve the index at which an error occurred, or -1 if the

error index has not been set.

UClassID getStaticClassID ()

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

ICU 2.2

UClassID getDynamicClassID ()

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