34. is_local_xxx ast helpers

The is_local module exposes collection of helper routines to establish locality of expression.

All functions and symbols are in “is_local” module, use require to get access to it.

require daslib/is_local

34.1. Scope checks

• is_local_expr (expr:smart_ptr<ast::Expression> const) : bool const

• is_local_or_global_expr (expr:smart_ptr<ast::Expression> const) : bool const

• is_scope_expr (expr:smart_ptr<ast::Expression> const) : bool const

is_local_expr(expr: ExpressionPtr)

is_local_expr returns bool const

argument	argument type
expr	ExpressionPtr

Returns true if the expression is local to the current scope.

is_local_or_global_expr(expr: ExpressionPtr)

is_local_or_global_expr returns bool const

argument	argument type
expr	ExpressionPtr

Returns true if expression is local the current scope or global scope.

is_scope_expr(expr: ExpressionPtr)

is_scope_expr returns bool const

argument	argument type
expr	ExpressionPtr

Returns true if the expression is a scoped expression, i.e. eventually points to a variable.

34.2. Uncategorized

is_shared_expr(expr: ExpressionPtr)

is_shared_expr returns bool const

argument	argument type
expr	ExpressionPtr

Returns true if the expression is local to the current scope.
