Class RZipFileMemberReaderStream

class RZipFileMemberReaderStream : public CBase;

Description

A RZipFileMemberReaderStream represents a input stream for compressed files in the archive. This is a friend class to CZipFile. In order to create a input stream for a file in the archive, CZipFile will call its member function GetInputStreamL() by passing a pointer to RZipFileMemberReaderStream and the function will return the input stream for the file

Derivation

• CBase - Base class for all classes to be instantiated on the heap

• RZipFileMemberReaderStream - A RZipFileMemberReaderStream represents a input stream for compressed files in the archive

IMPORT_C ~RZipFileMemberReaderStream();

Description

Destructor. All dynamically allocated data structures for this stream are freed.

IMPORT_C TInt Read(TDes16 &aDes, TInt aLength);

Description

Reads data from the stream buffer into the specified descriptor. On return, contains the data read from the stream buffer

Parameters

TDes16 &aDes The target descriptor for the data read from the stream buffer TInt aLength The maximum number of bytes to be read

Return value

TInt KErrNone If all bytes read successfully. KErrCorrupt If reading fails. KErrEof If end of file is reached. ... Any one of the system-wide error codes for other errors.

virtual TInt Read(TDes8 &aDes, TInt aLength);

Description

Overload version of the RZipFileMemberReaderStream read method. On return, contains the data read from the stream buffer.

Parameters

TDes8 &aDes The target descriptor for the data read from the stream buffer TInt aLength The maximum number of bytes to be read

Return value

TInt KErrNone If all bytes read successfully. KErrCorrupt If reading fails. KErrEof If end of file is reached. ... Any one of the system-wide error codes for other errors.

virtual void ReadL(TDes16 &aDes, TInt aLength);

Description

Overload version of the RZipFileMemberReaderStream readL method. On return, contains the data read from the stream buffer.

Parameters

TDes16 &aDes The target descriptor for the data read from the stream buffer TInt aLength The maximum number of bytes to be read

Leave codes

KErrNone If all bytes read successfully. KErrCorrupt If reading fails. KErrEof If end of file is reached. ... Any one of the system-wide error codes for other errors.
