Class SymbolTable

java.lang.Object

com.adobe.xfa.formcalc.SymbolTable

public final class SymbolTable
extends Object

Class SymbolTable defines the symbol table used by the FormCalc scripting engine. The FormCalc parser in fact, maintains two symbols tables: one for all built-in functions and a separate one for variables, parameters and functions.

The symbol table for built-ins is quite static in size, but its contents can span several invocations of yyparse(). Conversely, the symbol table for variables, parameters and functions needs to grow to as many variables, parameters and functions as are defined in the FormCalc script, and needs to contract its contents before each invocation of yyparse().
