Member Function Documentation

virtual void meta_context::end

(

)

[pure virtual]

The end method is called at the end of input.

Implemented in meta_context_sem, and meta_context_introspector.

virtual void meta_context::enumeration

(

const nstring &

s

)

[pure virtual]

The enumeration method is called when the parser sees a name in an enumeration tag place.

Parameters:

s	The name of the enumerand.

Implemented in meta_context_sem, and meta_context_introspector.

void meta_context::error	(	sub_context_ty *	scp,
		const char *	text
	)		[protected]

The lex_error method is a helper which proxies errors to the global lex_error function, for reporting error messages. (Reduces include explosion.)

Parameters:

scp	substitution context
text	the text of the error message

virtual void meta_context::field

(

const nstring &

name

)

[pure virtual]

The field method is called when the parser sees the start of a name=value field. The field_end method will be called after the value has been parsed.

Parameters:

name	The nam eof the field.

Implemented in meta_context_sem, and meta_context_introspector.

virtual void meta_context::field_end

(

)

[pure virtual]

The field_end method is called by the parser when it sees the end of a name=value field.

Implemented in meta_context_sem, and meta_context_introspector.

virtual void meta_context::integer

(

long

n

)

[pure virtual]

The integer method is called by the parser when an integer value is seen.

Parameters:

n	The value of the number.

Implemented in meta_context_sem, and meta_context_introspector.

virtual void meta_context::list

(

)

[pure virtual]

The list method is called when the parser sees the start of a list value. The pop method will be called after the value has been parsed.

Implemented in meta_context_sem, and meta_context_introspector.

virtual void meta_context::list_end

(

)

[pure virtual]

The list_end method is called by the parser when it sees the end of a list element.

Implemented in meta_context_sem, and meta_context_introspector.

meta_context& meta_context::operator=

(

const meta_context &

)

[private]

The assignment operator. Do not use.

virtual void meta_context::real

(

double

n

)

[pure virtual]

The real method is called by the parser when a floating point value is seen.

Parameters:

n	The value of the number.

Implemented in meta_context_sem, and meta_context_introspector.

virtual void meta_context::string

(

const nstring &

s

)

[pure virtual]

The string method is called by the parser when a string value is seen.

Parameters:

s	The value of the string constant.

Implemented in meta_context_sem, and meta_context_introspector.
