class Entry

extends java.lang.Object

implements java.io.Serializable

Entry class. Each entry contains the information of a piece of drawing/operation. The operation may be KILL, MOVE, COPY, NAMEANNOUNCE, NAMEREPLY, DROP, NEWPAGE. The drawing type may be BRUSH, TEXT, LINE, RECT, ROUNDRECT, OVAL, POLY. All types have some common attirbutes, such as entryID, typeID, personID. Each type has specific information. For a drawing type, these including page number, coordinates, color, boundary region, pen size, line width, etc. Some methods are also defined to operate the entry.
