class EST_Discrete

A class for managing mapping string names to integers and back again, mainly used for representing alphabets in n-grams and grammars etc.

Public Methods

	EST_Discrete ()
	EST_Discrete (const EST_Discrete &d)
	EST_Discrete (const EST_StrList &vocab) Initialise discrete class from given list of strings
	~EST_Discrete ()
void	copy (const EST_Discrete &d)
bool	init (const EST_StrList &vocab) (re-)initialise
const int	length (void) const The number of members in the discrete
const int	index (const EST_String &n) const The int assigned to the given name, if it doesn't exists p_def_val is returned (which is -1 by default)
const EST_String&	name (const int n) const The name given the index
void	def_val (const EST_String &v) set the default value when a name isn't found (-1 by default)
int	name (const EST_String &n) const An alternative method for getting the int form the name
EST_Discrete&	operator = (const EST_Discrete &a)

Documentation

A class for managing mapping string names to integers and back again, mainly used for representing alphabets in n-grams and grammars etc.

This offers an efficient way of mapping a known set of string names to integers. It is initialised from a list of names and builds a index of those names to a set of integers.

EST_Discrete()

EST_Discrete(const EST_Discrete &d)

EST_Discrete(const EST_StrList &vocab)

Initialise discrete class from given list of strings

~EST_Discrete()

void copy(const EST_Discrete &d)

bool init(const EST_StrList &vocab)

(re-)initialise

const int length(void) const

The number of members in the discrete

const int index(const EST_String &n) const

The int assigned to the given name, if it doesn't exists p_def_val is returned (which is -1 by default)

const EST_String& name(const int n) const

The name given the index

void def_val(const EST_String &v)

set the default value when a name isn't found (-1 by default)

int name(const EST_String &n) const

An alternative method for getting the int form the name

EST_Discrete& operator = (const EST_Discrete &a)

This class has no child classes.
