Enclosing class:

ZipFile

public static class ZipFile.Builder
extends AbstractStreamBuilder<ZipFile,ZipFile.Builder>

Builds new ZipFile instances.

The channel will be opened for reading, assuming the specified encoding for file names.

See SeekableInMemoryByteChannel to read from an in-memory archive.

By default the central directory record and all local file headers of the archive will be read immediately which may take a considerable amount of time when the archive is big. The ignoreLocalFileHeader parameter can be set to true which restricts parsing to the central directory. Unfortunately the local file header may contain information not present inside of the central directory which will not be available when the argument is set to true. This includes the content of the Unicode extra field, so setting ignoreLocalFileHeader to true means useUnicodeExtraFields will be ignored effectively.

Since:

1.26.0
