NAME

bson_validate_with_error − bson_validate_with_error()

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_with_error (const bson_t *bson,
                          bson_validate_flags_t flags,
                          bson_error_t *error);

PARAMETERS

	•		bson: A bson_t.
	•		flags: A bitwise−or of all desired validation flags.
	•		error: Optional bson_error_t.

DESCRIPTION

Validates a BSON document by walking through the document and inspecting the keys and values 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_NONE Basic validation of BSON length and structure.
	•		BSON_VALIDATE_UTF8 All keys and string values are checked for invalid UTF−8.
	•		BSON_VALIDATE_UTF8_ALLOW_NULL String values are allowed to have embedded NULL bytes.
	•		BSON_VALIDATE_DOLLAR_KEYS Prohibit keys that start with $ outside of a "DBRef" subdocument.
	•		BSON_VALIDATE_DOT_KEYS Prohibit keys that contain . anywhere in the string.
	•		BSON_VALIDATE_EMPTY_KEYS Prohibit zero−length keys.

RETURNS

Returns true if bson is valid; otherwise false and error is filled out.

The bson_error_t domain is set to BSON_ERROR_INVALID. Its code is set to one of the bson_validate_flags_t flags indicating which validation failed; for example, if a key contains invalid UTF−8, then the code is set to BSON_VALIDATE_UTF8, but if the basic structure of the BSON document is corrupt, the code is set to BSON_VALIDATE_NONE. The error message is filled out, and gives more detail if possible.

bson_visitor_t can be used for custom validation, Example Custom Validation.
