librdf_hash * librdf_new_hash (librdf_world *world,const char *name);
Constructor - create a new librdf_hash object.
librdf_hash * librdf_new_hash_from_string (librdf_world *world,const char *name,const char *string);
Constructor - create a new librdf_hash object from a string.
See librdf_hash_from_string for the string format.
librdf_hash * librdf_new_hash_from_array_of_strings (librdf_world *world,const char *name,const char **array);
Constructor - create a new librdf_hash object from an array of strings.
librdf_hash *
librdf_new_hash_from_hash (librdf_hash *old_hash);
Copy Constructor - create a new librdf_hash object from an existing one.
void
librdf_free_hash (librdf_hash *hash);
Destructor - destroy a librdf_hash object.
char * librdf_hash_get (librdf_hash *hash,const char *key);
Retrieve one value from hash for a given key as string.
The value returned is from newly allocated memory which the caller must free.
int librdf_hash_get_as_boolean (librdf_hash *hash,const char *key);
Lookup a hash key and decode value as a boolean.
False values: "no", "false" True values: "yes", "true"
long librdf_hash_get_as_long (librdf_hash *hash,const char *key);
Lookup a hash key and decode value as a long.
char * librdf_hash_get_del (librdf_hash *hash,const char *key);
Retrieve one value from hash for a given key as string and remove all values with that key.
The value returned is from newly allocated memory which the caller must free.
int librdf_hash_put_strings (librdf_hash *hash,const char *key,const char *value);
Insert key/value pairs into the hash as strings.
The key and values are copied into the hash, no sharing i s done.
void librdf_hash_print (librdf_hash *hash,FILE *fh);
Pretty print the hash to a file descriptor.
void librdf_hash_print_keys (librdf_hash *hash,FILE *fh);
Pretty print the keys to a file descriptor.
void librdf_hash_print_values (librdf_hash *hash,const char *key_string,FILE *fh);
Pretty print the values of one key to a file descriptor.
unsigned char * librdf_hash_interpret_template (const unsigned char *template_string,librdf_hash *dictionary,const unsigned char *prefix,const unsigned char *suffix);
Interpret keys in a template string to their value in a dictionary.
Can be used to do variable substitution for a string where
the syntax that marks the variable is defined by the prefix
and suffix
strings, and the variables are stored in the dictionary
hash table.
int librdf_hash_from_string (librdf_hash *hash,const char *string);
Initialise a hash from a string.
The string format is something like: key1='value1',key2='value2', key3='\'quoted value\''
The 's are required and whitespace can appear around the = and ,s
char * librdf_hash_to_string (librdf_hash *hash,const char *filter[]);
Format the hash as a string, suitable for parsing by librdf_hash_from_string.
Note: this method allocates a new string since this is a _to_ method
and the caller must call librdf_free_memory() to free the resulting memory.
