Detailed Description

An expression holding an expression table index.

Description

This derived class is not an actual expression type. It is to be used as an intermediate form when converting from the SETL expression table to the C expression form. All it contains is a single value which is the index of an expression in the expression table. See ExprTable.h

Member Function Documentation

void TableExpr::entry ( int ) [virtual]

Methods specified in derived class TableExpr.h.

Reimplemented from Expression.
Definition at line 6928 of file Expression.cc.
References _entry, and e.

int TableExpr::entry ( ) const [virtual]

Access the expression table index.

Reimplemented from Expression.
Definition at line 6934 of file Expression.cc.
References _entry.
Referenced by node_compare(), and update_signature().

Expression * TableExpr::clone ( ) const [virtual]

Return a copy of myself.

Implements Expression.
Definition at line 6922 of file Expression.cc.
References TableExpr().

virtual void TableExpr::print_debug ( ostream & o,

Boolean debug

) const [virtual]

debug indicates whether it should contain extra fields

Implements Expression.

virtual void TableExpr::convert ( BinRep & exprSet,

Symtab & symtab

) [virtual]

Read in the values of my fields and my subexpressions from the given BinRep object.
Convert(BinRep) expects the BinRep to be referencing an expression set of the same type as the expression. On return, all data from the expression set has been inserted into the appropriate fields in the expression object. NOTE that this converts the expression to an intermediate form which may contain TableExpr objects.
Implements Expression.

int TableExpr::structures_OK ( ) const [virtual]

Return 1 if my structures are in a valid state.

Implements Expression.

int TableExpr::exchange_expr ( VDL & vdl ) [virtual]

Create a node in the "expression" member and return the index.
