Default Constructor for write operation.

Default Constructor called for Read operation..

Destructor

Returns the charset for the plain text part

Commit the file and the store after it is written and and also closes the file.

ConstructL for Read operation.

ConstructWriteL for creating and writing to the plain bodytext file.

Converts the 8 bit chunk to unicode.When this is called iRfileReadBuf8 will have the 8-bit data that needs to be converted to unicode.8 bit data that is not converted is copied to iRemainingUnConvertedData, which is used in conversion when this is called again.

Converts the 8 bit chunk to Unicode.

Returns the default charset for the plain text part

Cancel the file read operation and set the filepointer to the current position of the file so that next call to NextChunkL() will attempt to read the same chunk that was cancelled

Asynchronously retrives the body text chunks.If body is stored as 8bit, converts the chunk to Unicode.

Extracts a chunk of iChunkMaxLength or less, from the CRichText object.

Extracts a chunk of iChunkMaxLength or less, from the CRichText object.

The NewL factory function for Write operation.

Overloaded NewL for Read operation.

Creates the character converter and specifies the character set to convert to or from. Leaves if the specified or default character set is not available.

Revert/Delete the file if it is not committed.

Set iCharsetId to aCharset if body text of the message was downloaded as 8 bit. This can be used to override the charset with which a message was downloaded, when the body text is opened for reading.

Returns the size of body text in bytes.

The charset of the body text

Pointer to a 16 bit chunk that is being read from the store.

Pointer to a 8 bit chunk that is being read from the store.

Contains the size of the chunk that will be read or write in the RFile

Character converter for 8 to 16 bit conversion.

The RFile to which body text is written.

The RFile Path.

Indicates whether to store text as 8 bit or 16 bit.

Indicates whether the Rfile is commited or not.

Indicates whether the chunk being read is last.

Enum indicating if RFile is being written or read

To access APIs related to RFile operations.

The position from where to extract data in CRichText

Indicates whether call to DoRunl was initiated by PreviousChunkL method.

Contains the remaining converted Unicode Data

Contains the remaining unconverted Unicode Data

Indicates whether call to DoRunl was initiated by 8 bit PreviousChunkL and NextChunkL methods.

Buffer used to read data from RFile.

Pointer to 8-bit buffer that needs to be written to RFile.

Array that stores the start positions of each chunk,in Rfile

Contains the start position of the next chunk

Temporary buffer created to Store chunk while it is being written aynchronously.
