bson_iter_visit_all: A convenience function to iterate all remaining fields of iter using the callback vtable provided by visitor.

NAME

bson_iter_visit_all() - A convenience function to iterate all remaining fields of iter using the callback vtable provided by visitor.

SYNOPSIS

bool
bson_iter_visit_all (bson_iter_t          *iter,
                     const bson_visitor_t *visitor,
                     void                 *data);

PARAMETERS

iter
A bson_iter_t \&.

visitor
A bson_visitor_t \&.

data
Optional data for visitor \&.

DESCRIPTION

A convenience function to iterate all remaining fields of iter using the callback vtable provided by visitor \&.

RETURNS

true if visitation was pre-maturely stopped by a callback function. Otherwise false.

  • bson_iter_value (3) - Fetches the value for the currently observed type as a boxed type. This allows passing around the value without knowing the type at runtime.
  • bson_iter_array (3) - The bson_iter_array() function shall retrieve the raw buffer of a sub-array from iter. iter MUST be on an element that is of type BSON_TYPE_ARRAY. This can be verified with bson_iter_type() or the BSON_ITER_HOLDS_ARRAY() macro.
  • bson_iter_as_bool (3) - Fetches the current field as if it were a boolean.
  • bson_iter_as_int64 (3) - The bson_iter_as_int64() function shall return the contents of the current element as if it were a BSON_TYPE_INT64 element. The currently supported casts include:
  • bson_iter_binary (3) - This function shall return the binary data of a BSON_TYPE_BINARY element. It is a programming error to call this function on a field that is not of type BSON_TYPE_BINARY. You can check this with the BSON_ITER_HOLDS_BINARY() macro or bson_iter_type().
  • bson_iter_bool (3) - The bson_iter_bool()function shall return the boolean value of a BSON_TYPE_BOOL element. It is a programming error to call this function on an element other than BSON_TYPE_BOOL. You can check this with bson_iter_type() or BSON_ITER_HOLDS_BOOL().
  • bson_iter_code (3) - This function returns the contents of a BSON_TYPE_CODE field. The length of the string is stored in length if non-NULL.
  • bson_iter_codewscope (3) - The bson_iter_codewscope() function acts similar to bson_iter_code() except for BSON_TYPE_CODEWSCOPE elements. It also will provide a pointer to the buffer for scope, which can be loaded into a bson_t using bson_init_static().
  • bson_iter_date_time (3) - The bson_iter_date_time() function shall return the number of miliseconds since the UNIX epoch, as contained in the BSON_TYPE_DATE_TIME element.
  • bson_iter_dbpointer (3) - Fetches the contents of a BSON_TYPE_DBPOINTER element.
  • bson_iter_document (3) - The bson_iter_document() function shall retrieve the raw buffer of a sub-document from iter. iter MUST be on an element that is of type BSON_TYPE_DOCUMENT. This can be verified with bson_iter_type() or the BSON_ITER_HOLDS_DOCUMENT() macro.
  • bson_iter_double (3) - Fetches the contents of a BSON_TYPE_DOUBLE field.
  • bson_iter_dup_utf8 (3) - This function is similar to bson_iter_utf8() except that it calls bson_strndup() on the result.
  • bson_iter_find (3) - The bson_iter_find()function shall advance iterto the element named keyor exhaust all elements of iter. If iteris exhausted, false is returned and itershould be considered invalid.
