Detailed Description

TxtExpUtils Implements various utility functions that help in the process of importing text files, as featured in the TextImportFilter.

Member Enumeration Documentation

enum TxtExpUtils::Modifier

Specifies a type of katakana modifier. The following sounds contain a dakuten: ga, gi, gu, ge, go, za, zi, zu, ze, zo, da, di, zu, de, do, ba, bi, bu, be, bo vu (not very common) The following sounds contain a han-dakuten: pa, pi, pu, pe, po

Member Function Documentation

IIntData * TxtExpUtils::GetEncodingIntData ( bool16  bRelease = kFalse )

static

Gets the IntData pointer for the encoding option so that the dialog and the filter could both set and get the same IntData interface. The code that first calls GetEncodingIntData should release it when all done. (See TxtExpFilter::TxtExpFilter() and TxtExpFilter::~TxtExpFilter().)

Parameters

bRelease

Set to kTrue if you want to release the IIntData pointer. Defaults to kFalse.

Returns

Pointer to IIntData interface.

textchar TxtExpUtils::HankakuToZenkaku ( const textchar  tc, const TxtExpUtils::Modifier  modifier = TxtExpUtils::None  )

static

Converts a Hankaku (single-byte) katakana char to its Zenkaku (dual-byte) counterpart.

Parameters

tc	Textchar containing the single-byte code for the Hankaku katakana.
modifier	Specifies whether the hankaku character has a modifier or not. See typedef Modifier. If modifier is other than None, then tc's HIBYTE is ignored.

Returns

Textchar containing the dual-byte code for the Zenkaku katakana. The tc is not found in the lookup table, this returns kTextChar_Null.

ITxtExpFileWriter * TxtExpUtils::QueryTxtExpFileWriter ( ITxtExpFileWriter::Encoding  encoding )

static

Obtains the actual ITxtExpFileWriter interface for the corresponding encoding.

Parameters

encoding

The encoding for which you want the ITxtExpFileWriter implementation. See ITxtExpFileWriter::Encoding.

textchar TxtExpUtils::ZenkakuToHankaku ( const textchar  tc, TxtExpUtils::Modifier &  modifier  )

static

Converts a Zenkaku (dual-byte) katakana char to its Hankaku (single-byte) counterpart.

Parameters

tc	Textchar containing the dual-byte code for the Zenkaku katakana. If the textchar has a modifier, then the high-order byte contains the actual modifier character. (dakuten or handakuten)
modifier	(return by reference) Indicates whether the returned textchar has a modifier.

Returns

Textchar containing the single-byte code for the Hankaku katakana. The tc is not found in the lookup table, this returns kTextChar_Null.

Member Data Documentation

const int32 TxtExpUtils::kKatakanaNotFound = -1

static

Constant that signifies that the character was not found in the lookup table.

const int32 TxtExpUtils::kNumKatakana = 94

static

Constant for the number of katakana entries in the lookup table.

const int32 TxtExpUtils::kZenkakuColumn = 1

static
