Detailed Description

Decodes a ZIP file from a stream.

This can enumerate the items in a ZIP file and can create suitable stream objects to read each one.

Constructor & Destructor Documentation

◆ ZipFile() [1/4]

juce::ZipFile::ZipFile ( const File file)
explicit

Creates a ZipFile to read a specific file.

Definition at line 241 of file juce_ZipFile.cpp.

◆ ZipFile() [2/4]

juce::ZipFile::ZipFile ( InputStream inputStream,
bool  deleteStreamWhenDestroyed 
)

Creates a ZipFile for a given stream.

Parameters
inputStreamthe stream to read from
deleteStreamWhenDestroyedif set to true, the object passed-in will be deleted when this ZipFile object is deleted

Definition at line 227 of file juce_ZipFile.cpp.

◆ ZipFile() [3/4]

juce::ZipFile::ZipFile ( InputStream inputStream)
explicit

Creates a ZipFile for a given stream.

The stream will not be owned or deleted by this class - if you want the ZipFile to manage the stream's lifetime, use the other constructor.

Definition at line 236 of file juce_ZipFile.cpp.

◆ ZipFile() [4/4]

juce::ZipFile::ZipFile ( InputSource inputSource)
explicit

Creates a ZipFile for an input source.

The inputSource object will be owned by the zip file, which will delete it later when not needed.

Definition at line 246 of file juce_ZipFile.cpp.

◆ ~ZipFile()

juce::ZipFile::~ZipFile ( )

Destructor.

Definition at line 251 of file juce_ZipFile.cpp.

Member Function Documentation

◆ getNumEntries()

int juce::ZipFile::getNumEntries ( ) const
noexcept

Returns the number of items in the zip file.

Definition at line 269 of file juce_ZipFile.cpp.

Referenced by juce::ZipFile::Builder::writeToStream().

◆ getEntry() [1/2]

const ZipFile::ZipEntry * juce::ZipFile::getEntry ( int  index) const
noexcept

Returns a structure that describes one of the entries in the zip file.

This may return a nullptr if the index is out of range.

◆ getIndexOfFileName()

int juce::ZipFile::getIndexOfFileName ( const String fileName,
bool  ignoreCase = false 
) const
noexcept

Returns the index of the first entry with a given filename.

This uses a case-sensitive comparison to look for a filename in the list of entries. It might return -1 if no match is found.

◆ getEntry() [2/2]

const ZipFile::ZipEntry * juce::ZipFile::getEntry ( const String fileName,
bool  ignoreCase = false 
) const
noexcept

Returns a structure that describes one of the entries in the zip file.

This uses a case-sensitive comparison to look for a filename in the list of entries. It might return 0 if no match is found.

◆ sortEntriesByFilename()

void juce::ZipFile::sortEntriesByFilename ( )

◆ createStreamForEntry() [1/2]

InputStream * juce::ZipFile::createStreamForEntry ( int  index)

Creates a stream that can read from one of the zip file's entries.

The stream that is returned must be deleted by the caller (and a nullptr might be returned if a stream can't be opened for some reason).

The stream must not be used after the ZipFile object that created has been deleted.

Note that if the ZipFile was created with a user-supplied InputStream object, then all the streams which are created by this method will by trying to share the same source stream, so cannot be safely used on multiple threads! (But if you create the ZipFile from a File or InputSource, then it is safe to do this).

◆ createStreamForEntry() [2/2]

InputStream * juce::ZipFile::createStreamForEntry ( const ZipEntry entry)

Creates a stream that can read from one of the zip file's entries.

The stream that is returned must be deleted by the caller (and a nullptr might be returned if a stream can't be opened for some reason).

The stream must not be used after the ZipFile object that created has been deleted.

◆ uncompressTo()

Result juce::ZipFile::uncompressTo ( const File targetDirectory,
bool  shouldOverwriteFiles = true 
)

Uncompresses all of the files in the zip file.

This will expand all the entries into a target directory. The relative paths of the entries are used.

Parameters
targetDirectorythe root folder to uncompress to
shouldOverwriteFileswhether to overwrite existing files with similarly-named ones
Returns
success if the file is successfully unzipped

◆ uncompressEntry()

Result juce::ZipFile::uncompressEntry ( int  index,
const File targetDirectory,
bool  shouldOverwriteFiles = true 
)

Uncompresses one of the entries from the zip file.

This will expand the entry and write it in a target directory. The entry's path is used to determine which subfolder of the target should contain the new file.

Parameters
indexthe index of the entry to uncompress - this must be a valid index between 0 and (getNumEntries() - 1).
targetDirectorythe root folder to uncompress into
shouldOverwriteFileswhether to overwrite existing files with similarly-named ones
Returns
success if all the files are successfully unzipped
