Detailed Description

The representation of a named function call or arbitrary C expression.

Don't use this for logic and and logic or, as this will produce code that runs constructor and destructors regardless of the result of the LHS.

Constructor & Destructor Documentation

more::lang::cx_pattern::cx_pattern (  char const *    pattern, ct_type const *    result_type, va_list    va )

Construct an expression of the form pattern which evaluates to result_type and with arguments from va. Occurances of "%!" in pattern are substituted with argument expressions. If pattern is not a string literal, you must make sure it outlives this object, e.g. by copying it to a GC allocated segment. By convention the whole expression in pattern is surrounded by parentheses, rather than each sub-expression. That is, it is assumed that all code that is printed is printed such that it has top-level precedence.

Member Function Documentation

virtual void more::lang::cx_pattern::append_ctors_to (  cx_block *    blk )  [virtual]

Append constructors of this expression to blk. Reimplemented from more::lang::cx_expr.

virtual void more::lang::cx_pattern::append_dtors_to (  cx_block *    blk )  [virtual]

Append destructors of this expression to blk. Implementations of this function shall not declare variables in blk. Reimplemented from more::lang::cx_expr.

virtual void more::lang::cx_pattern::print_as_expr (  std::ostream &    os )  const [virtual]

Print the C source code of this expression. The default implementation thows a logic error. This function may be overloaded to extend the backend, otherwise it may be easier to transform the source code. Reimplemented from more::lang::cx_expr.
