bson_validate()¶

Synopsis¶

typedef enum {
   BSON_VALIDATE_NONE = 0,
   BSON_VALIDATE_UTF8 = (1 << 0),
   BSON_VALIDATE_DOLLAR_KEYS = (1 << 1),
   BSON_VALIDATE_DOT_KEYS = (1 << 2),
   BSON_VALIDATE_UTF8_ALLOW_NULL = (1 << 3),
   BSON_VALIDATE_EMPTY_KEYS = (1 << 4),
} bson_validate_flags_t;

bool
bson_validate (const bson_t *bson, bson_validate_flags_t flags, size_t *offset);

Parameters¶

bson: A bson_t.
flags: A bitwise-or of all desired bson_validate_flags_t.
offset: A location for the offset within bson where the error ocurred.

Description¶

Validates a BSON document by walking through the document and inspecting the fields for valid content.

You can modify how the validation occurs through the use of the flags parameter. A description of their effect is below.

BSON_VALIDATE_UTF8 will request that all UTF-8 strings are checked to contain valid UTF-8 sequences. This is expensive and disabled by default.
BSON_VALIDATE_UTF8_ALLOW_NULL will specify that UTF-8 strings are allowed to have embedded NULL bytes. Many UTF-8 implementations use a 2-byte squence for embedded NULLs so that they work with stanard libc functions. Libbson expects this by default.
BSON_VALIDATE_DOLLAR_KEYS will request that all key names are checked to ensure they do not start with the ASCII dollar character ($).
BSON_VALIDATE_DOT_KEYS will request that all key names are checked to ensure they do not contain an ASCII dot (.) character.
BSON_VALIDATE_EMPTY_KEYS will request that zero-length key names are prohibited.

Returns¶

Returns true if bson is valid; otherwise false and offset is set to the byte offset where the error was detected.
