The various parse tables must be constructed, etc. before calling any routines in this class.<p> Three classes are produced by this code: <dl> <dt> symbol constant class <dd> this contains constant declarations for each terminal (and optionally each non-terminal). <dt> action class <dd> this non-public class contains code to invoke all the user actions that were embedded in the parser specification. <dt> parser class <dd> the specialized parser class consisting primarily of some user supplied general and initialization code, and the parse tables. </dl><p> Three parse tables are created as part of the parser class: <dl> <dt> production table <dd> lists the LHS non terminal number, and the length of the RHS of each production. <dt> action table <dd> for each state of the parse machine, gives the action to be taken (shift, reduce, or error) under each lookahead symbol.<br> <dt> reduce-goto table <dd> when a reduce on a given production is taken, the parse stack is popped back a number of elements corresponding to the RHS of the production. This reveals a prior state, which we transition out of under the LHS non terminal symbol for the production (as if we had seen the LHS symbol rather than all the symbols matching the RHS). This table is indexed by non terminal numbers and indicates how to make these transitions. </dl><p> In addition to the method interface, this class maintains a series of public global variables and flags indicating how misc. parts of the code and other output is to be produced, and counting things such as number of conflicts detected (see the source code and public variables below for more details).<p> This class is "static" (contains only static data and methods).<p><P><P><DL><DT><B>Version:</B></DT> <DD>last update: 11/25/95</DD><DT><B>Author:</B></DT> <DD>Scott Hudson</DD><DT><B>See
