Function documentation

const Expression* slang::ast::CallExpression::thisClass() const

If this call is for a class method, returns the expression representing the class handle on which the method is being invoked.

Otherwise returns nullptr.

std::span<const Expression*const> slang::ast::CallExpression::arguments() const

Returns the arguments to the call.

std::span<const Expression*> slang::ast::CallExpression::arguments()

Returns the arguments to the call.

bool slang::ast::CallExpression::isSystemCall() const

Returns true if this is a call of a system subroutine.

std::string_view slang::ast::CallExpression::getSubroutineName() const

Returns the name of the subroutine being called.

SubroutineKind slang::ast::CallExpression::getSubroutineKind() const

Returns the kind of subroutine being called.

parsing::KnownSystemName slang::ast::CallExpression::getKnownSystemName() const

Returns the known system name for the subroutine, if it's a built-in subroutine.

bool slang::ast::CallExpression::hasOutputArgs() const

Returns true if the called subroutine has output (or inout / ref) arguments.
