Public Methods

 SymbolTable (VMDApp *vmdapp)
 ~SymbolTable (void)
ParseTree * parse (const char *seltext)
 parse selection text, return a new ParseTree on success, NULL on error. More...

void add_keyword (const char *visible, SymbolTableElement::int_fctn get, SymbolTableElement::set_int_fctn set)
void add_keyword (const char *visible, SymbolTableElement::double_fctn get, SymbolTableElement::set_double_fctn set)
void add_keyword (const char *visible, SymbolTableElement::string_fctn get, SymbolTableElement::set_string_fctn set)
void add_singleword (const char *visible, SymbolTableElement::single_fctn get, SymbolTableElement::set_single_fctn set)
void add_stringfctn (const char *visible, SymbolTableElement::stringfctn_fctn get)
void add_cfunction (const char *visible, c_ddfunc fctn)
 Register C functions that take a double and return a double as atom selection functions. Note: These functions must return the same output for given input. Functions like rand() will break some optimizations in the atom selection code otherwise. More...

int find_attribute (const char *attrib)
 find keyword/function matching the name and return function index, or -1. More...

int is_changeable (int fctnidx)
 returns '1' if the variable can be changed/ modified. More...

int num_custom_singleword ()
 Query what custom singlewords have been defined. Note: these include those have been deleted, because the implementation of remove_custom only sets the string to "". Text API's will want to only return the strings that have nonzero length. More...

const char * custom_singleword_name (int)
 Return name with given index, or NULL if not defined. More...

int add_custom_singleword (const char *name, const char *macro)
 add a new singleword macro. More...

const char * get_custom_singleword (const char *name)
 get the macro for the given singleword. More...

int remove_custom_singleword (const char *name)
 delete the given singleword macro. More...
