Detailed Description

The file interface provides access to a single file.

The IFile object can be created by the IFileInterface object.

Member Function Documentation

GetPosition()

virtual UInt64 Murl::IFile::GetPosition ( )

pure virtual

Get the position of the file pointer.

Read() / Write() operations start at the file pointer position, the default position is zero.

Returns

The position of the file pointer in bytes.

Implemented in Murl::Util::File.

SetPosition()

virtual void Murl::IFile::SetPosition ( UInt64  position )

pure virtual

Set the position of the file pointer.

Read() / Write() operations start at the file pointer position, the default position is zero.

Parameters

position

The position of the file pointer in bytes.

Implemented in Murl::Util::File.

GetSize()

virtual UInt64 Murl::IFile::GetSize ( )

pure virtual

Get the size of the file.

Returns

The size of the file in bytes.

Implemented in Murl::Util::File.

Read() [1/2]

virtual UInt64 Murl::IFile::Read ( void *  data, UInt64  byteSize  )

pure virtual

Read from the file at the current file pointer position.

Parameters

data	The memory pointer to read the file into.
byteSize	The number of bytes to read.

Returns

The number of bytes read into the memory.

Implemented in Murl::Util::File.

Write() [1/2]

virtual UInt64 Murl::IFile::Write ( const void *  data, UInt64  byteSize  )

pure virtual

Write to the file at the current file pointer position.

Parameters

data	The memory pointer to write into the file.
byteSize	The number of bytes to write.

Returns

The number of bytes written into the file.

Implemented in Murl::Util::File.

Read() [2/2]

virtual UInt64 Murl::IFile::Read ( Data &  data )

pure virtual

Read from the file at the current file pointer position.

The size of the data object's data is the number of bytes to read, if the data object is empty the data is resized to GetSize().

Parameters

data	The data object to read the file into.

Returns

The number of bytes read into the data object.

Implemented in Murl::Util::File.

Write() [2/2]

virtual UInt64 Murl::IFile::Write ( const ConstData &  data )

pure virtual

Write to the file at the current file pointer position.

Parameters

data	The data object to write into the file.

Returns

The number of bytes written into the file.

Implemented in Murl::Util::File.
