Description

Interface Summary

IJPTreeParser	Common interface for our tree parsers.
Primative	Field and Variable implement Primative because they both have a "primative" Progress data type (INTEGER, CHARACTER, etc).
SymbolI
Value	Represents objects that have a value.
WidgetI

Class Summary

Block	For keeping track of blocks, block attributes, and the things that are scoped within those blocks - especially buffer scopes.
BufferScope	A record of a BufferSymbol scope to a Block.
Call	Represents a Call to some 4GL procedure.
CQ	Context qualifiers.
Dataset	A Symbol defined with DEFINE DATASET.
Datasource	A Symbol defined with DEFINE DATA-SOURCE.
DataType	One static instance of DataType is created for each data type in the 4GL.
ErrorList	A list of SemanticError objects found during a tree parse.
Expression
FieldBuffer	FieldBuffer is the Symbol object linked to from the AST for schema, temp, and work table fields, and FieldBuffer provides the link to the Field object.
FieldContainer	Frame and Browse widgets are FieldContainers.
FieldLookupResult	For field lookups, we need to be able to pass back the BufferScope object as well as the Field object.
Parameter
ParseUnit	Provides parse unit information, such as the symbol table and a reference to the AST.
Query	A Symbol defined with DEFINE QUERY.
Routine	Represents the definition of a Routine.
RunHandle	Represents a procedure handle value, used in a run statement of the form: run in .
SemanticRecord	Represents a record used in semantic processing.
Stream	A Symbol defined with DEFINE STREAM or any other syntax which implicitly define a stream.
Symbol	Base class for any type of symbol which needs to be kept track of when parsing a 4gl compile unit's AST.
SymbolFactory	Create a Symbol of the appropriate subclass.
SymbolScope	For keeping track of PROCEDURE, FUNCTION, and trigger scopes within a 4gl compile unit.
SymbolScopeRoot	A ScopeRoot object is created for each compile unit, and it represents the program (topmost) scope.
SymbolScopeSuper	Contains skeleton symbols for purposes of inheritance.
TableBuffer	A TableBuffer is a Symbol which provides a link from the syntax tree to a Table object.
TreeParserWrapper	This class just makes it easier to interface with an Antlr generated tree parser.
Variable	A Symbol defined with DEFINE VARIABLE or any of the other various syntaxes which implicitly define a variable.
Widget	A Symbol defined with DEFINE or any of the other various syntaxes which implicitly define a widget.

Error Summary

SemanticError

Represents a semantic error found in 4GL code while analysing it.
