class ZipContainer::Container

The mime-type of this ZipContainer file.

Create a new ZipContainer file on disk with the specified mimetype.

# File lib/zip-container/container.rb, line 95
def Container.create(filename, mimetype, &block)
  ::Zip::ZipOutputStream.open(filename) do |stream|
    stream.put_next_entry(MIMETYPE_FILE, nil, nil, ::Zip::ZipEntry::STORED)
    stream.write mimetype
  end

  # Now open the newly created container.
  c = new(filename)

  if block_given?
    begin
      yield c
    ensure
      c.close
    end
  end

  c
end

Iterate over the entries in the ZipContainer file. The entry objects returned by this method are Zip::ZipEntry objects. Please see the rubyzip documentation for details.

# File lib/zip-container/container.rb, line 122
def Container.each_entry(filename, &block)
  c = new(filename)

  if block_given?
    begin
      c.each(&block)
    ensure
      c.close
    end
  end

  c.each
end

Open an existing ZipContainer file from disk. It will be checked for conformance upon first access.

# File lib/zip-container/container.rb, line 142
def Container.open(filename, &block)
  c = new(filename)

  if block_given?
    begin
      yield c
    ensure
      c.close
    end
  end

  c
end

Verify that the specified ZipContainer file conforms to the specification. This method returns false if there are any problems at all with the file (including if it cannot be found).

# File lib/zip-container/container.rb, line 162
def Container.verify(filename)
  begin
    new(filename).verify!
  rescue
    return false
  end

  true
end

Verify that the specified ZipContainer file conforms to the specification. This method raises exceptions when errors are found or if there is something fundamental wrong with the file itself (e.g. it cannot be found).

# File lib/zip-container/container.rb, line 179
def Container.verify!(filename)
  new(filename).verify!
end

Convenience method for adding the contents of a file to the ZipContainer file. If asked to add a file with a reserved name, such as the special mimetype header file, this method will raise a ReservedNameClashError.

See the rubyzip documentation for details of the continue_on_exists_proc parameter.

# File lib/zip-container/container.rb, line 193
def add(entry, src_path, &continue_on_exists_proc)
  if reserved_entry?(entry) || managed_directory?(entry)
    raise ReservedNameClashError.new(entry.to_s)
  end

  @zipfile.add(entry, src_path, &continue_on_exists_proc)
end

Returns the ZipContainer file comment, if it has one.

# File lib/zip-container/container.rb, line 387
    

Set the ZipContainer file comment to the new value.

# File lib/zip-container/container.rb, line 394
    

Commits changes that have been made since the previous commit to the ZipContainer file. Returns true if anything was actually done, false otherwise.

# File lib/zip-container/container.rb, line 208
def commit
  return false unless commit_required?

  if on_disk?
    @zipfile.commit
  end
end

Returns true if any changes have been made to this ZipContainer file since the last commit, false otherwise.

# File lib/zip-container/container.rb, line 402
    

Returns an object which can be used like ruby’s built in Dir (class) object, except that it works on the ZipContainer file on which this method is invoked.

See the rubyzip documentation for details.

# File lib/zip-container/container.rb, line 226
def dir
  @fs_dir
end

Iterate over the entries in the ZipContainer file. The entry objects returned by this method are Zip::ZipEntry objects. Please see the rubyzip documentation for details.

# File lib/zip-container/container.rb, line 412
    

Returns an Enumerable containing all the entries in the ZipContainer file The entry objects returned by this method are Zip::ZipEntry objects. Please see the rubyzip documentation for details.

# File lib/zip-container/container.rb, line 421
    

Extracts the specified entry of the ZipContainer file to dest_path.

See the rubyzip documentation for details of the on_exists_proc parameter.

# File lib/zip-container/container.rb, line 431
    

Returns an object which can be used like ruby’s built in File (class) object, except that it works on the ZipContainer file on which this method is invoked.

See the rubyzip documentation for details.

# File lib/zip-container/container.rb, line 238
def file
  @fs_file
end

Searches for entries within the ZipContainer file with the specified name. Returns nil if no entry is found. See also get_entry.

# File lib/zip-container/container.rb, line 439
    

Searches for an entry within the ZipContainer file in a similar manner to find_entry, but throws +Errno::ENOENT+ if no entry is found.

# File lib/zip-container/container.rb, line 447
    

Returns an input stream to the specified entry. If a block is passed the stream object is passed to the block and the stream is automatically closed afterwards just as with ruby’s built in File.open method.

# File lib/zip-container/container.rb, line 457
    

Returns an output stream to the specified entry. If a block is passed the stream object is passed to the block and the stream is automatically closed afterwards just as with ruby’s built-in File.open method.

See the rubyzip documentation for details of the permission_int parameter.

# File lib/zip-container/container.rb, line 252
def get_output_stream(entry, permission = nil, &block)
  if reserved_entry?(entry) || managed_directory?(entry)
    raise ReservedNameClashError.new(entry.to_s)
  end

  @zipfile.get_output_stream(entry, permission, &block)
end

Searches for entries within the ZipContainer file that match the given glob.

See the rubyzip documentation for details of the parameters that can be passed in.

# File lib/zip-container/container.rb, line 469
    

Is this ZipContainer file memory resident as opposed to stored on disk?

# File lib/zip-container/container.rb, line 264
def in_memory?
  !@on_disk
end

Creates a directory in the ZipContainer file. If asked to create a directory with a name reserved for use by a file this method will raise a ReservedNameClashError.

The new directory will be created with the supplied unix-style permissions. The default (0755) is owner read, write and list; group read and list; and world read and list.

# File lib/zip-container/container.rb, line 278
def mkdir(name, permission = 0755)
  if reserved_entry?(name) || managed_file?(name)
    raise ReservedNameClashError.new(name)
  end

  @zipfile.mkdir(name, permission)
end

Returns the filename of this ZipContainer file.

# File lib/zip-container/container.rb, line 476
    

Is this ZipContainer file stored on disk as opposed to memory resident?

# File lib/zip-container/container.rb, line 290
def on_disk?
  @on_disk
end

Returns a string containing the contents of the specified entry.

# File lib/zip-container/container.rb, line 483
    

Removes the specified entry from the ZipContainer file. If asked to remove any reserved files such as the special mimetype header file this method will do nothing.

# File lib/zip-container/container.rb, line 300
def remove(entry)
  return if reserved_entry?(entry)
  @zipfile.remove(entry)
end

Renames the specified entry in the ZipContainer file. If asked to rename any reserved files such as the special mimetype header file this method will do nothing. If asked to rename a file to one of the reserved names a ReservedNameClashError is raised.

See the rubyzip documentation for details of the continue_on_exists_proc parameter.

# File lib/zip-container/container.rb, line 315
def rename(entry, new_name, &continue_on_exists_proc)
  return if reserved_entry?(entry)
  raise ReservedNameClashError.new(new_name) if reserved_entry?(new_name)

  @zipfile.rename(entry, new_name, &continue_on_exists_proc)
end

Replaces the specified entry of the ZipContainer file with the contents of src_path (from the file system). If asked to replace any reserved files such as the special mimetype header file this method will do nothing.

# File lib/zip-container/container.rb, line 329
def replace(entry, src_path)
  return if reserved_entry?(entry)
  @zipfile.replace(entry, src_path)
end

Returns the number of entries in the ZipContainer file.

# File lib/zip-container/container.rb, line 490
  

Return a textual summary of this ZipContainer file.

# File lib/zip-container/container.rb, line 338
def to_s
  @zipfile.to_s + " - #{@mimetype}"
end

Verify the contents of this ZipContainer file. All managed files and directories are checked to make sure that they exist, if required.
