Detailed Description

The dimeInput class offers transparent file I/O for DXF and DXB.

Constructor & Destructor Documentation

◆ dimeInput()

dimeInput::dimeInput ( )

Constructor.

◆ ~dimeInput()

dimeInput::~dimeInput ( )

Destructor.

Member Function Documentation

◆ eof()

bool dimeInput::eof ( ) const

Returns true if end of file is encountered.

◆ getFilePosition()

int dimeInput::getFilePosition ( ) const

For ASCII files, it returns the current line number. For binary files the file position is returned.

Referenced by dimeModel::read().

◆ getMemHandler()

dimeMemHandler * dimeInput::getMemHandler ( )

Returns the memory handler used in this model.

References dimeModel::getMemHandler().

Referenced by dimeBlocksSection::read(), dimeTablesSection::read(), dimeTable::read(), dimeStringRecord::read(), dimeInsert::read(), dimeModel::read(), dimeRecordHolder::read(), dimeBlock::read(), dimePolyline::read(), dimeEntity::readEntities(), and dimeRecord::readRecord().

◆ getModel()

dimeModel * dimeInput::getModel ( )

Returns the model for this file.

Referenced by dimeLayerTable::read(), dimeInsert::read(), dimeBlock::read(), and dimeEntity::read().

◆ getVersion()

int dimeInput::getVersion ( ) const

Returns the version of this file (10, 12, 13 or 14).

◆ isAborted()

bool dimeInput::isAborted ( ) const

This method returns wether file input was aborted or not.

◆ isBinary()

bool dimeInput::isBinary ( ) const

Returns true if this is a binary (DXB) file.

◆ putBackGroupCode()

void dimeInput::putBackGroupCode ( const int32 code )

This function is needed when a loader snoops for future group codes. It is possible to put back a single group code so that the next time dimeInput::readGroupCode() is called, the putback value will be returned.

Referenced by dimeRecordHolder::read().

◆ readDouble()

bool dimeInput::readDouble ( dxfdouble & val )

Reads a dxfdouble precision floating point number from the file.

Referenced by dimeDoubleRecord::read(), readFloat(), and dimeRecord::readRecordData().

◆ readFloat()

bool dimeInput::readFloat ( float & val )

Reads a single precision floating point number from the file.

References readDouble().

Referenced by dimeFloatRecord::read(), and dimeRecord::readRecordData().

◆ readGroupCode()

bool dimeInput::readGroupCode ( int32 & code )

Reads a group code from the file. In binary files, group codes are represented as a single byte, with the exception of extended data which has 255 as the first byte, and then the actual group code following as a 16-bit integer.

References readInt16(), readInt32(), readString(), and relativePosition().

Referenced by dimeBlocksSection::read(), dimeTablesSection::read(), dimeTable::read(), dimeModel::read(), dimeRecordHolder::read(), dimePolyline::read(), dimeEntity::readEntities(), and dimeRecord::readRecord().

◆ readInt16()

bool dimeInput::readInt16 ( int16 & val )

Reads a 16 bit integer from the file.

Referenced by dimeTable::read(), dimeInt16Record::read(), readGroupCode(), and dimeRecord::readRecordData().

◆ readInt32()

bool dimeInput::readInt32 ( int32 & val )

Reads a 32 bit integer from the file.

Referenced by dimeInt32Record::read(), readGroupCode(), and dimeRecord::readRecordData().

◆ readInt8()

bool dimeInput::readInt8 ( int8 & val )

Reads an 8 bit integer from the file.

Referenced by dimeInt8Record::read(), and dimeRecord::readRecordData().

◆ readString()

const char * dimeInput::readString ( )

Returns a null-terminated string read from the file. The string is valid only until the next read operation, so you'd better copy it somewhere if you need it.

References dimeModel::registerHandle().

Referenced by dimeBlocksSection::read(), dimeTablesSection::read(), dimeTable::read(), dimeStringRecord::read(), dimeModel::read(), dimePolyline::read(), dimeEntity::readEntities(), readGroupCode(), and dimeRecord::readRecordData().

◆ readStringNoSkip()

const char * dimeInput::readStringNoSkip ( )

Special version of readString() that does not skip leading blanks. This is used for reading TEXT primary values, group_code = 1.

References dimeModel::registerHandle().

Referenced by dimeRecord::readRecordData().

◆ relativePosition()

float dimeInput::relativePosition ( )

Returns the relative file position. 0.0 means beginning of file, 1.0 is at end of file.

Referenced by readGroupCode().

◆ setCallback()

void dimeInput::setCallback	(	int()(float, void )	cb,
		void *	cbdata
	)

This method sets a progress callback that will be called with a float in the range between 0 and 1, and void * cbdata as arguments.

◆ setFile()

bool dimeInput::setFile ( const char *const filename )

Opens the file 'filename' for reading. True is returned if the file is opened correctly. File will be closed in destructor.

References setFilePointer().

◆ setFileHandle()

bool dimeInput::setFileHandle ( FILE * fp )

Sets the input data to the stream fp. \fp must be a valid file/stream, and will not be closed in the destuctor. No progress information will be avilable during loading if this method is used.

◆ setFilePointer()

bool dimeInput::setFilePointer ( const int newfd )

Sets the file pointer for this instance. newfd is a file opened with the unistd open() function.
