## 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.

Definition at line 35 of file juce_ZipFile.h.

## Class Documentation

## ◆ juce::ZipFile::ZipEntry

struct juce::ZipFile::ZipEntry

  ZipFile::getEntry

Definition at line 72 of file juce_ZipFile.h.

Class Members
uint32 | externalFileAttributes | Platform specific data. Depending on how the zip file was created this may contain macOS and Linux file types, permissions and setuid/setgid/sticky bits.
String | filename | The name of the file, which may also include a partial pathname.
Time | fileTime | The last time the file was modified.
bool | isSymbolicLink | True if the zip entry is a symbolic link.
int64 | uncompressedSize | The file's original size.

## Constructor & Destructor Documentation

## ◆ ZipFile() [1/4]

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

Creates a ZipFile to read a specific file.

Definition at line 254 of file juce_ZipFile.cpp.

## ◆ ZipFile() [2/4]

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

Creates a ZipFile for a given stream.

Parameters

  inputStream | the stream to read from
  deleteStreamWhenDestroyed | if set to true, the object passed-in will be deleted when this ZipFile object is deleted

Definition at line 240 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 249 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 259 of file juce_ZipFile.cpp.

## ◆ ~ZipFile()

juce::ZipFile::~ZipFile | ( |  | ) |

Destructor.

Definition at line 264 of file juce_ZipFile.cpp.

## Member Function Documentation

## ◆ createStreamForEntry() [1/2]

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.

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).

Definition at line 336 of file juce_ZipFile.cpp.

## ◆ createStreamForEntry() [2/2]

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).

## ◆ getEntry() [1/2]

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.

  ZipFile::ZipEntry

Definition at line 309 of file juce_ZipFile.cpp.

## ◆ getEntry() [2/2]

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.

See also
  ZipFile::ZipEntry

Definition at line 287 of file juce_ZipFile.cpp.

## ◆ 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.

See also
  ZipFile::ZipEntry

Definition at line 295 of file juce_ZipFile.cpp.

## ◆ getNumEntries()

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

Returns the number of items in the zip file.

Definition at line 282 of file juce_ZipFile.cpp.

## ◆ sortEntriesByFilename()

void juce::ZipFile::sortEntriesByFilename | ( |  | ) |

Sorts the list of entries, based on the filename.

Definition at line 345 of file juce_ZipFile.cpp.

## ◆ uncompressEntry() [1/2]

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

  index | the index of the entry to uncompress - this must be a valid index between 0 and (getNumEntries() - 1).
  targetDirectory | the root folder to uncompress into
  shouldOverwriteFiles | whether to overwrite existing files with similarly-named ones

Returns
  success if all the files are successfully unzipped

Definition at line 415 of file juce_ZipFile.cpp.

## ◆ uncompressEntry() [2/2]

Result juce::ZipFile::uncompressEntry | ( | int | index,
|  | const File & | targetDirectory,
|  | OverwriteFiles | overwriteFiles,
|  | FollowSymlinks | followSymlinks )

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

  index | the index of the entry to uncompress - this must be a valid index between 0 and (getNumEntries() - 1).
  targetDirectory | the root folder to uncompress into
  overwriteFiles | whether to overwrite existing files with similarly-named ones
  followSymlinks | whether to follow symlinks inside the target directory

Returns
  success if all the files are successfully unzipped

Definition at line 423 of file juce_ZipFile.cpp.

## ◆ 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

  targetDirectory | the root folder to uncompress to
  shouldOverwriteFiles | whether to overwrite existing files with similarly-named ones

Returns
  success if the file is successfully unzipped
