Class ZipLong
java.lang.Object
org.apache.commons.compress.archivers.zip.ZipLong
- All Implemented Interfaces:
Serializable,Cloneable
Utility class that represents a four byte integer with conversion rules for the little-endian byte order of ZIP files.
- See Also:
- This class is immutable

Field Details
-
CFH_SIG
Central File Header Signature -
LFH_SIG
Local File Header Signature -
DD_SIG
Data Descriptor signature.Actually, PKWARE uses this as marker for split/spanned archives and other archivers have started to use it as Data Descriptor signature (as well).
- Since:
- 1.1
-
SINGLE_SEGMENT_SPLIT_MARKER
Marks ZIP archives that were supposed to be split or spanned but only needed a single segment in then end (so are actually neither split nor spanned).This is the "PK00" prefix found in some archives.
- Since:
- 1.5
-
AED_SIG
Archive extra data record signature.- Since:
- 1.5
-

ZipLong
Constructs a new instance from bytes.- Parameters:
bytes- the bytes to store as a ZipLong
-
ZipLong
Creates instance from the four bytes starting at offset.- Parameters:
bytes- the bytes to store as a ZipLongoffset- the offset to start
-
ZipLong
create instance from a Java int.- Parameters:
value- the int to store as a ZipLong- Since:
- 1.15
-
ZipLong
Creates instance from a number.- Parameters:
value- the long to store as a ZipLong

putLong
put the value as four bytes in big-endian byte order.- Parameters:
value- the Java long to convert to bytesbuf- the output bufferoffset- The offset within the output buffer of the first byte to be written. must be non-negative and no larger thanbuf.length-4
