UniqId LAMGetCurrentGraphyId ( const LexicalAssocMem * lexical_memory )

Return the unique identifier associated to the current position.

Return the identifier of the word corresponding to the current exploring position.

Return the length of the current word.

Return the length of the word associated to the current exploring position

Remarks:: The value returned is increment at every valid goCharacterForward call, decremented at every valid goCharacterBackward call, and reset to 0 at every goToRoot call.

Parameters:

[in] lexical_memory The lexical memory to explore

Returns:: The length of the word corresponding to the current exploring position

LexicalDataType LAMGetDataType ( const LexicalAssocMem * lexical_memory )

Return the lexical entry given by its unique corresponding identifier.

Remarks:: In a given lexical memory, any stored entry corresponds to a unique identifier and any valid identifier corresponds to a unique stored entry.

Parameters:

`[in]`	lexical_memory	The lexical memory
`[in]`	identifier	The entry identifier

Returns:: The corresponding entry

LexicalCharacter LAMGetNextAvailableCharacter ( LexicalAssocMem * lexical_memory )

Return the next character available at the current position.

This function can be called until its returns NO_CHARACTER, signifying that all possible characters have been returned. At this point, a further call to getNextAvailableCharacter goes back to the first lexical character available.

Parameters:

Iteratively return all the graphies stored in a lexical memory. This function can be called until its returns NULL, signifying that all stored graphies have been returned.

Parameters:

Parameters:

[in] lexical_memory The lexical memory

Returns:: The number of entries stored

void LAMGoCharacterBackward ( LexicalAssocMem * lexical_memory )

Step one lexical character backward the current position.

Step backward the current exploring position from one lexical character. The exploring informations of the position before the call are lost so that when one goes back to that position, available characters inventory start again from the beginning.

Remarks:: This function has no effect if the current position is the root of the lexical memory

Parameters:

[in] lexical_memory The lexical memory to explore

See also:: LAMGoCharacterForward() LAMGoToRoot()

void LAMGoCharacterForward ( LexicalAssocMem * lexical_memory )

Step one lexical character forward the current position.

Step forward the current exploring position from one lexical character, that is the value returned by the last call of getNextAvailableCharacter from the current exploring position. Each time this function is called, the current state is saved so that when one go back to a given exploring position using goCharacterBackward, the available characters inventory with getNextAvailableCharacter carries on as if the current position had not been left.

Remarks:: This function has no effect if getNextAvailableCharacter has not been called at least one time or no character is available from the current exploring position

Parameters:

[in] lexical_memory The lexical memory to explore

See also:: LAMIsAtEndOfGraphy() LAMGoToRoot()

void LAMGoToFirstEntry ( LexicalAssocMem * lexical_memory )

Go back to the first graphy stored in a lexical memory.

This function can be called anytime to order to start again the lexical memory inventory (with getNextEntry) from the beginning.

Parameters:

void LAMGoToRoot ( LexicalAssocMem * lexical_memory )

Set the current position to the root of the lexical memory.

Assign the current exploring position to the root of the lexical memory, i.e. before the first lexical character.

		const char *	filename
	)

Save a lexical memory in a file.

Save the content of a lexical memory in a binary (machine readable) file. The function returns a not null error code if operation fails.
