ZipStream\GeneralPurposeBitFlag Class Reference

Public Attributes
const	COMPRESSED_PATCHED_DATA = 1 << 5
	If this bit is set, this indicates that the file is compressed patched data.
const	DEFLATE_COMPRESSION_FAST = 10 << 1
	(For Methods 8 and 9 - Deflating) Fast (-ef) compression option was used.
const	DEFLATE_COMPRESSION_MAXIMUM = 1 << 1
	(For Methods 8 and 9 - Deflating) Maximum (-exx/-ex) compression option was used.
const	DEFLATE_COMPRESSION_NORMAL = 0 << 1
	(For Methods 8 and 9 - Deflating) Normal (-en) compression option was used.
const	DEFLATE_COMPRESSION_SUPERFAST = 11 << 1
	(For Methods 8 and 9 - Deflating) Super Fast (-es) compression option was used.
const	EFS = 1 << 11
	Language encoding flag (EFS).
const	ENCRYPT_CENTRAL_DIRECTORY = 1 << 13
	Set when encrypting the Central Directory to indicate selected data values in the Local Header are masked to hide their actual values.
const	ENCRYPTED = 1 << 0
	If set, indicates that the file is encrypted.
const	LZMA_EOS = 1 << 1
	If the compression method used was type 14, LZMA, then this bit, if set, indicates an end-of-stream (EOS) marker is used to mark the end of the compressed data stream.
const	STRONG_ENCRYPTION = 1 << 6
	Strong encryption.
const	ZERO_HEADER = 1 << 3
	If this bit is set, the fields crc-32, compressed size and uncompressed size are set to zero in the local header.

Member Data Documentation

EFS

const ZipStream\GeneralPurposeBitFlag::EFS = 1 << 11

Language encoding flag (EFS).

If this bit is set, the filename and comment fields for this file MUST be encoded using UTF-8.

LZMA_EOS

const ZipStream\GeneralPurposeBitFlag::LZMA_EOS = 1 << 1

If the compression method used was type 14, LZMA, then this bit, if set, indicates an end-of-stream (EOS) marker is used to mark the end of the compressed data stream.

If clear, then an EOS marker is not present and the compressed data size must be known to extract.

STRONG_ENCRYPTION

const ZipStream\GeneralPurposeBitFlag::STRONG_ENCRYPTION = 1 << 6

Strong encryption.

If this bit is set, you MUST set the version needed to extract value to at least 50 and you MUST also set bit 0. If AES encryption is used, the version needed to extract value MUST be at least 51.

ZERO_HEADER

const ZipStream\GeneralPurposeBitFlag::ZERO_HEADER = 1 << 3

If this bit is set, the fields crc-32, compressed size and uncompressed size are set to zero in the local header.

The correct values are put in the data descriptor immediately following the compressed data.
