Detailed Description

An operator that is represented by native C code.  This is always
a leaf operand in the AST.  This class is also used to represent
the code to be generated for 'if' and 'with' expressions.

gen_transform()

void c_expr::gen_transform ( FILE * f, int indent, const char * dest, bool , int , const char * , capture_info * , dt_operand ** = 0, int = 0 )

finaloverridevirtual

Generate code for a c_expr which is either the expression inside
an if statement or a sequence of statements which computes a
result to be stored to DEST.   

Reimplemented from operand.
