Detailed Description

The base class for expressions which can be directly coded into C source and possibly evaluated runtime.

Client code does not need to use this a the base class for expression (e.g. if virtual functions are undesirable). Instead the client expressions may be transformed into C cx_expr instances.

Member Function Documentation

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

Append constructors of this expression to blk. Reimplemented in more::lang::cx_block, more::lang::cx_expr_with_ctor_dtor, more::lang::cx_literal, more::lang::cx_call, more::lang::cx_switch, more::lang::cx_lambda, more::lang::cx_cond, more::lang::cx_pattern, more::lang::cx_and, more::lang::cx_locator, and more::lang::cx_package_variable.

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

Append destructors of this expression to blk. Implementations of this function shall not declare variables in blk. Reimplemented in more::lang::cx_block, more::lang::cx_expr_with_ctor_dtor, more::lang::cx_literal, more::lang::cx_call, more::lang::cx_switch, more::lang::cx_lambda, more::lang::cx_cond, more::lang::cx_pattern, more::lang::cx_and, more::lang::cx_locator, and more::lang::cx_package_variable.

virtual void more::lang::cx_expr::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 in more::lang::rt_closure, more::lang::cx_block, more::lang::cx_identifier, more::lang::cx_literal, more::lang::cx_call, more::lang::cx_lambda, more::lang::cx_cond, more::lang::cx_pattern, and more::lang::cx_and.

virtual void more::lang::cx_expr::print_as_stmt (  std::ostream &    os )  const [virtual]

Print this expression as a C statement. The default implementation calls print_source and then appends a semicolon. Reimplemented in more::lang::cx_block, more::lang::cx_switch, and more::lang::cx_cond.

void more::lang::cx_expr::set_type (  ct_type const *    rtt )  [inline]

Change the type of the expression.

ct_type const* more::lang::cx_expr::type_of (    )  const [inline]

Return the type of the expression. Reimplemented in more::lang::cx_lambda.
