Member Function Documentation

copyDataTo()

virtual void OdStreamBuf::copyDataTo ( OdStreamBuf *  pDestination, OdUInt64  sourceStart = 0, OdUInt64  sourceEnd = 0  )

virtual

Copies the specified bytes from this StreamBuf object to the specified StreamBuf object.

Parameters

pDestination	[in] Pointer to the StreamBuf object to receive the data.
sourceStart	[in] Starting position of the file pointer of this StreamBuf object.
sourceEnd	[in] Ending position of the file pointer of this StreamBuf object.

Remarks

Bytes are copied from sourceStart to sourceEnd inclusive.

Reimplemented in OdFlatMemStream.

fileName()

virtual OdString OdStreamBuf::fileName ( )

virtual

Returns the name of the file associated with this StreamBuf object.

Reimplemented in OdMemoryStream.

getByte()

virtual OdUInt8 OdStreamBuf::getByte ( )

virtual

Returns the byte at the current position of the file pointer for this StreamBuf object, and increments the pointer.

Reimplemented in OdMemoryStreamImpl< OdMemoryStream >, and OdFlatMemStreamImpl< OdStreamBuf >.

getBytes()

virtual void OdStreamBuf::getBytes ( void *  buffer, OdUInt32  numBytes  )

virtual

Returns the specified number of bytes, starting at the current position of the file pointer for this StreamBuf object, and increments the pointer by numBytes.

Parameters

buffer	[in] Character buffer.
numBytes	[in] Number of bytes.

Reimplemented in OdFlatMemStreamImpl< OdStreamBuf >, and OdMemoryStreamImpl< OdMemoryStream >.

getShareMode()

virtual OdUInt32 OdStreamBuf::getShareMode ( )

virtual

Returns the share mode for this StreamBuf object.

Remarks

getShareMode returns one of the following:

Value Description Oda::kShareDenyReadWrite 0x10 deny read/write mode Oda::kShareDenyWrite 0x20 deny write mode Oda::kShareDenyRead 0x30 deny read mode Oda::kShareDenyNo 0x40 deny none mode

isEof()

virtual bool OdStreamBuf::isEof ( )

virtual

Returns true if and only if the current position of the file pointer for this StreamBuf object is at the end of file.

Reimplemented in OdMemoryStreamImpl< OdMemoryStream >, and OdStreamPosImpl< OdStreamBuf >.

length()

virtual OdUInt64 OdStreamBuf::length ( )

virtual

Returns the length in bytes of the file associated with this StreamBuf object.

Reimplemented in OdMemoryStreamImpl< OdMemoryStream >, and OdStreamPosImpl< OdStreamBuf >.

ODRX_DECLARE_MEMBERS()

OdStreamBuf::ODRX_DECLARE_MEMBERS

(

OdStreamBuf

)

putByte()

virtual void OdStreamBuf::putByte ( OdUInt8  value )

virtual

Writes the byte to the current position of the file pointer for this StreamBuf object, and increments the pointer.

Parameters

value

[in] Byte to write.

Reimplemented in OdFlatMemStreamImpl< OdStreamBuf >, and OdMemoryStreamImpl< OdMemoryStream >.

putBytes()

virtual void OdStreamBuf::putBytes ( const void *  buffer, OdUInt32  numBytes  )

virtual

Writes the specified number of bytes, starting at the current position of the file pointer for this StreamBuf object, and increments the pointer by numBytes.

Parameters

buffer	[in] Character buffer.
numBytes	[in] Number of bytes.

Reimplemented in OdFlatMemStreamImpl< OdStreamBuf >, and OdMemoryStreamImpl< OdMemoryStream >.

rewind()

virtual void OdStreamBuf::rewind ( )

virtual

Sets the current position of the file pointer for this StreamBuf object to zero.

Reimplemented in OdMemoryStreamImpl< OdMemoryStream >.

seek()

virtual OdUInt64 OdStreamBuf::seek ( OdInt64  offset, OdDb::FilerSeekType  seekType  )

virtual

Moves the current position of the file pointer for this StreamBuf object to the specified location.

Parameters

offset	[in] Number of bytes.
seekType	[in] Seek type.

Remarks

seekType must be one of the following:

Value Description. OdDb::kSeekFromStart SEEK_SET Start of file. OdDb::kSeekFromCurrent SEEK_CUR Current position of file pointer. OdDb::kSeekFromEnd SEEK_END End of file.

Reimplemented in OdMemoryStreamImpl< OdMemoryStream >, and OdStreamPosImpl< OdStreamBuf >.

tell()

virtual OdUInt64 OdStreamBuf::tell ( )

virtual

Returns the current position of the file pointer for this StreamBuf object.

Reimplemented in OdMemoryStreamImpl< OdMemoryStream >, and OdStreamPosImpl< OdStreamBuf >.

truncate()

virtual void OdStreamBuf::truncate ( )

virtual

Sets the length of the file associated with this StreamBuf object to zero.

Reimplemented in OdMemoryStreamImpl< OdMemoryStream >.
