Member Function Documentation

◆ accept()

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.

◆ add()

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

inherited

It adds the argument to the function list of arguments.

Parameters

It returns the i-th function argument.

Parameters

i	The argument position.

Returns: The it-th function argument.

◆ getFirst()

Expression * te::da::BinaryFunction::getFirst ( ) const

inherited

It returns the first function argument.

Returns: The first function argument.

◆ getName()

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

inlineinherited
