Member Function Documentation

YBlock::REP_BODY

(

YBlock

)

[private]

virtual bool YBlock::isBlock

(

const [inline, virtual]

yes

Reimplemented from YCode.

virtual ykind YBlock::kind

(

const [inline, virtual]

return type (interesting mostly for function calls)

Reimplemented from YCode.

void YBlock::setType

(

constTypePtr

YCPValue YBlock::evaluate

(

bool

cse = false

const [virtual]

used for error reporting

Implements Y2Namespace.

SymbolTable * YBlock::table

(

)

const [virtual]

get our whole symbol table?

Reimplemented from Y2Namespace.

Y2Function * YBlock::createFunctionCall	(	const string	name,
		constFunctionTypePtr	type
	)			[virtual]

Creates a function call instance, which can be used to call a function from this namespace. The object is NOT owned anymore by this instance, the caller can (and should) delete it.

Parameters:

	name	name of the required function
	type	the type of the function (needed for overloading)

Returns:

an object, that can be used to call the function, or NULL on error

Implements Y2Namespace.
