Member Function Documentation

virtual ReturnType te::common::BaseVisitable< QueryVisitor , void >::accept ( VisitorType & guest ) const

pure virtualinherited

It call the visit method from the guest object.

Parameters

guest The guest or visitor.

Returns: Any valid value define by the template type R.

void te::da::Function::add ( Expression * arg )

inherited

It adds the argument to the function list of arguments.

Parameters

arg	The argument to be added.

Note: The Function will take the ownership of the given argument.

Expression* te::da::UnaryOp::clone ( ) const

virtual

It creates a new copy of this expression.

Reimplemented from te::da::UnaryFunction.

Expression* te::da::Function::getArg ( std::size_t i ) const

inherited

It returns the i-th function argument.

Parameters

i	The argument position.

Returns: The it-th function argument.

Expression* te::da::UnaryFunction::getArgument ( ) const

inherited

It returns the function associated argument.

Returns: The function associated argument.

const std::string& te::da::Function::getName ( ) const

inlineinherited

It returns the function name.

Returns: The function name.

Definition at line 79 of file Function.h.

std::size_t te::da::Function::getNumArgs ( ) const

inherited

It returns the number of arguments informed to the function.

Returns: The number of parameters.

UnaryOp& te::da::UnaryOp::operator= ( const UnaryOp & rhs )

Assignment operator.

Expression* te::da::Function::operator[] ( std::size_t i ) const

inherited

It returns the i-th function argument.

Parameters

i	The argument position.

Returns: The it-th function argument.

void te::da::UnaryFunction::setArgument ( Expression * arg )

inherited

It sets the function argument.

Parameters

arg	The single function argument.

Note: The UnaryFunction will take the ownership of the given argument.
