TOP Package xbn.placeholder Description

Intended to be used only as "placeholders", by functions needing to return multiple things at once. The format of the name of each class in this package is [abbrev1]_[abbrev2]_[...], where abbrev* is defined in the doclet class map. For example, functions that return two StringBuffers and a char return an object named placeholder.sb_sb_c.

Each "placeholder" class has

• Public variables holding the "things". For example, sb_sb_c has two public StringBuffers (named sb1 and sb2), and a char (named c).
• An empty constructor, used when you need to create the object before assigning values to the things.
• A constructor in which each of the values are set. For example, sb_sb_c has the constructor sb_sb_c(StringBuffer sb_1, StringBuffer sb_2, char c_har)

In addition, UtilPHFromObj has a convenience function for casting an Object (and array of objects) to each placeholder class. For example, UtilPHFromObj.getsb_sb_c(o_sbsbc) and getAOsb_sb_c(ao_sbsbc). The purpose of this function is to make using VWObject easier, when compiling a set.
