ZipEntry (TrueZIP Driver ZIP 7.7.3 API)

java.lang.Object
- de.schlichtherle.truezip.zip.ZipEntry

All Implemented Interfaces:

Cloneable

Direct Known Subclasses:

ZipDriverEntry
```
@NotThreadSafe
public class ZipEntry
extends Object
implements Cloneable
```
Drop-in replacement for java.util.zip.ZipEntry. For every numeric property of this class, the default value is UNKNOWN in order to indicate an unknown state and it's permitted to set this value explicitly in order to reset the property.
Note that a ZipEntry object can be used with only one ZipFile or ZipOutputStream instance. Reusing the same ZipEntry object with a second object of these classes is an error and may result in unpredictable behaviour.
In general, this class is not thread-safe. However, it is safe to call only the getters of this class from multiple threads concurrently.

```
  - setSize
```
public final void setSize(long size)
```
    Sets the uncompressed size of this entry.
    
    Parameters:
    size - The (Uncompressed) Size.
    
    Throws:
    
    IllegalArgumentException - If size is not in the range from 0 to ULong.MAX_VALUE (9223372036854775807L).
