Detailed Description

Class that supports the reading of zip archives via the zlib unzip API.

The methods of this class should only be called on the thread that creates the object.

Member Function Documentation

◆ Close()

virtual bool CefZipReader::Close ( )
pure virtual

Closes the archive.

This should be called directly to ensure that cleanup occurs on the correct thread.

◆ CloseFile()

virtual bool CefZipReader::CloseFile ( )
pure virtual

Closes the file.

◆ Create()

static CefRefPtr<CefZipReader> CefZipReader::Create ( CefRefPtr< CefStreamReader stream)
static

Create a new CefZipReader object.

The returned object's methods can only be called from the thread that created the object.

◆ Eof()

virtual bool CefZipReader::Eof ( )
pure virtual

Returns true if at end of the file contents.

◆ GetFileLastModified()

virtual CefBaseTime CefZipReader::GetFileLastModified ( )
pure virtual

Returns the last modified timestamp for the file.

◆ GetFileName()

virtual CefString CefZipReader::GetFileName ( )
pure virtual

The below methods act on the file at the current cursor position.

Returns the name of the file.

◆ GetFileSize()

virtual int64_t CefZipReader::GetFileSize ( )
pure virtual

Returns the uncompressed size of the file.

◆ MoveToFile()

virtual bool CefZipReader::MoveToFile ( const CefString fileName,
bool  caseSensitive 
)
pure virtual

Moves the cursor to the specified file in the archive.

If |caseSensitive| is true then the search will be case sensitive. Returns true if the cursor position was set successfully.

◆ MoveToFirstFile()

virtual bool CefZipReader::MoveToFirstFile ( )
pure virtual

Moves the cursor to the first file in the archive.

Returns true if the cursor position was set successfully.

◆ MoveToNextFile()

virtual bool CefZipReader::MoveToNextFile ( )
pure virtual

Moves the cursor to the next file in the archive.

Returns true if the cursor position was set successfully.

◆ OpenFile()

virtual bool CefZipReader::OpenFile ( const CefString password)
pure virtual

Opens the file for reading of uncompressed data.

A read password may optionally be specified.

◆ ReadFile()

virtual int CefZipReader::ReadFile ( void *  buffer,
size_t  bufferSize 
)
pure virtual

Read uncompressed file contents into the specified buffer.

Returns < 0 if an error occurred, 0 if at the end of file, or the number of bytes read.

◆ Tell()

virtual int64_t CefZipReader::Tell ( )
pure virtual

Returns the current offset in the uncompressed file contents.
