Constructors Summary
public ZipEntry(String name) Creates a new zip entry with the specified name. param name the entry name exception NullPointerException if the entry name is null exception IllegalArgumentException if the entry name is longer than 0xFFFF bytes /* Zip library is loaded from System.initializeSystemClass */ initIDs(); if (name == null) { throw new NullPointerException(); } if (name.length() > 0xFFFF) { throw new IllegalArgumentException("entry name too long"); } this.name = name;
public ZipEntry(ZipEntry e) Creates a new zip entry with fields taken from the specified zip entry. param e a zip Entry object name = e.name; time = e.time; crc = e.crc; size = e.size; csize = e.csize; method = e.method; extra = e.extra; comment = e.comment;
ZipEntry(String name, long jzentry) this.name = name; initFields(jzentry);

Methods Summary
public java.lang.Object	clone() Returns a copy of this entry. try { ZipEntry e = (ZipEntry)super.clone(); e.extra = (extra == null ? null : (byte[])extra.clone()); return e; } catch (CloneNotSupportedException e) { // This should never happen, since we are Cloneable throw new InternalError(); }

public long	getTime() Returns the modification time of the entry, or -1 if not specified. return the modification time of the entry, or -1 if not specified see #setTime(long) return time != -1 ? dosToJavaTime(time) : -1;
public int	hashCode() Returns the hash code value for this entry. return name.hashCode();
