Field Detail

LFH_SIG

static final int LFH_SIG

Local File Header signature.

DD_SIG

static final int DD_SIG

Data Descriptor signature.

Constant Field Values

CFH_SIG

static final int CFH_SIG

Central File Header signature.

Constant Field Values

ZIP64_EXT

static final boolean ZIP64_EXT

This boolean field is set by the system property de.schlichtherle.util.zip.zip64ext. If this property is set to true (case is ignored), then ZIP64 extensions are always added when writing a ZIP archive file, regardless of its size. This system property is intended for testing purposes only. During normal operations, it should not be set as many third party tools would not treat the redundant ZIP64 extensions correctly. Note that it's impossible to inhibit ZIP64 extensions.

ZIP64_EOCDR_SIG

static final int ZIP64_EOCDR_SIG

Zip64 End Of Central Directory Record.

ZIP64_EOCDL_SIG

static final int ZIP64_EOCDL_SIG
