Member Function Documentation

UT_Error IE_Imp_Text::_constructStream	(	ImportStream *&	pStream,
		GsfInput *	fp
	)			`[protected, virtual]`

Create a stream of the appropriate type

Parameters:

	pStream	Pointer to created stream
	fp	File to construct stream from

Override this virtual function to derive from the text importer

Reimplemented in IE_Imp_ISCII.

UT_Error IE_Imp_Text::_parseStream ( ImportStream * pStream ) [protected]

Parse stream contents into the document

Parameters:

stream

Stream to import from

This code is used for both files and the clipboard

UT_Error IE_Imp_Text::_recognizeEncoding	(	const char *	szBuf,
		UT_uint32	iNumbytes
	)			`[protected]`

Detect encoding of text buffer

Parameters:

	pData	Buffer
	lenData	Length of buffer

Supports UTF-8 and UCS-2 big and little endian CJK encodings could be added

UT_Error IE_Imp_Text::_recognizeEncoding ( GsfInput * fp ) [protected]

Detect encoding of text file

Parameters:

fp

File

Supports UTF-8 and UCS-2 big and little endian CJK encodings could be added

void IE_Imp_Text::_setEncoding ( const char * szEncoding ) [protected]

Set importer's encoding and related members

Parameters:

szEncoding

Encoding to export file into

Decides endian and BOM policy based on encoding. Set to 0 to handle raw bytes. This function should be identical to the one in IE_Exp_Text.
