Constructor & Destructor Documentation

virtual rpt_value_error::~rpt_value_error

(

)

[virtual]

The destructor.

rpt_value_error::rpt_value_error	(	const rpt_position::pointer &	where,
		const nstring &	what
	)			[private]

The constructor. It is private on purpose, use the "create" class method instead.

Parameters:

	where	Where the error occurred.
	what	What went wrong.

rpt_value_error::rpt_value_error

(

)

[private]

The default constructor. Do not use.

rpt_value_error::rpt_value_error

(

const rpt_value_error &

)

[private]

The copy constructor. Do not use.

Member Function Documentation

static rpt_value::pointer rpt_value_error::create

(

string_ty *

what

)

[static]

The create class method is used to create new dynamically allocated instances of this class.

Parameters:

what

What went wrong.

static rpt_value::pointer rpt_value_error::create

(

const nstring &

what

)

[static]

The create class method is used to create new dynamically allocated instances of this class.

Parameters:

what

What went wrong.

static rpt_value::pointer rpt_value_error::create	(	const rpt_position::pointer &	where,
		string_ty *	what
	)			[static]

The create class method is used to create new dynamically allocated instances of this class.

Parameters:

	where	Where the error occurred.
	what	What went wrong.

static rpt_value::pointer rpt_value_error::create	(	const rpt_position::pointer &	where,
		const nstring &	what
	)			[static]

The create class method is used to create new dynamically allocated instances of this class.

Parameters:

	where	Where the error occurred.
	what	What went wrong.

nstring rpt_value_error::query

(

)

const

The query method may be used to obtain the human readable representation of the error.

void rpt_value_error::setpos

(

const rpt_position::pointer &

where

)

The setpos method may be used to update the recorded position of the error.

void rpt_value_error::print

(

)

const

The print method may be used to print the error message, including the position if one has been provided.

const char* rpt_value_error::name

(

)

const [protected, virtual]

The name method is used to obtain the name of the type of the value.

Implements rpt_value.

bool rpt_value_error::is_an_error

(

)

const [protected, virtual]

The is_an_error method may be used to determine whether or not an object instance is an error instance. This happens often enoygh that the code is clear this way than using a dynamic_cast<rpt_value_error *>

Returns:

true for error instances, false for everything else

Reimplemented from rpt_value.

rpt_value_error& rpt_value_error::operator=

(

const rpt_value_error &

)

[private]

The assignment operator. Do not use.
