Detailed Description

Thai string cell custering.

Function Documentation

void th_init_cell (struct thcell_t * cell)

Initialize a Thai cell. Parameters:

cell : pointer to the cell to initialize

Initializes values in the Thai cell struct.

size_t th_make_cells (const thchar_t * s, size_t len, struct thcell_t cells[], size_t * ncells, int is_decomp_am)

Tokenize string into cells. Parameters:

s : the string
len : the length of string
cells : the array of output cells buffer
ncells : the address of integer storing the number of cells provided by the buffer, and to keep the number of resulting cells on return
is_decomp_am : whether SARA AM is to be decomposed into NIKHANIT and SARA AA and to be in separate cells

Returns:

total characters consumed

Tokenizes the string bounded by s and len into cells, and stores at most *ncells resulting cells in the cells buffer. On return, *ncells is also set to the total cells stored in cells[].

size_t th_next_cell (const thchar_t * s, size_t len, struct thcell_t * cell, int is_decomp_am)

Get first cell from string. Parameters:

s : the string
len : the length of string
cell : the output buffer
is_decomp_am : whether SARA AM is to be decomposed into NIKHANIT and SARA AA and to be in separate cells

Returns:

total chars consumed by the cell

Gets first cell from the string bounded by s and len, and, if cell is not null, stores the cell data in it.

size_t th_prev_cell (const thchar_t * s, size_t pos, struct thcell_t * cell, int is_decomp_am)

Get previous cell from string. Parameters:

s : the string
pos : the position in string to get cell previous to
cell : the output buffer
is_decomp_am : whether SARA AM is to be decomposed into NIKHANIT and SARA AA and to be in separate cells

Returns:

total chars consumed by the cell

Gets last cell from the string bounded by s and pos, and if cell is not null, stores the cell data in it.
