Member Function Documentation

void ace::NGramToken::init

(

void

)

[static]

Performs class start-up initialization.

Must be called earlier than any of get() methods.

NGram * ace::NGramToken::get	(	const raw_ngram_t &	raw_ngram,
		ngram_type_t	ngram_type
	)			[static]

Parameters:

	raw_ngram	Source raw N-gram.
	ngram_type	Type of N-gram to be created (determines which members of `raw_ngram` are copied).

Returns:

Pointer to temporary NGram instance constructed on the basis of given params.

NGram * ace::NGramToken::get	(	const NGram *	source,
		ngram_type_t	ngram_type
	)			[static]

Parameters:

	source	Pointer to source N-gram (full type) which should be downcasted.
	ngram_type	Type of N-gram to be created (determines which members of `source` are copied).

Returns:

Pointer to temporary NGram instance downcast constructed on the basis of given params.
