Buffer

Copies the buffer.

Note:

Buffer#copy does not mark target as modified so you must copy from a MongooseBuffer for it to work as expected. This is a work around since copy modifies the target, not this.

Determines if this buffer is equals to other buffer

Sets the subtype option and marks the buffer modified.

SubTypes:

const bson = require('bson')
bson.BSON_BINARY_SUBTYPE_DEFAULT
bson.BSON_BINARY_SUBTYPE_FUNCTION
bson.BSON_BINARY_SUBTYPE_BYTE_ARRAY
bson.BSON_BINARY_SUBTYPE_UUID
bson.BSON_BINARY_SUBTYPE_MD5
bson.BSON_BINARY_SUBTYPE_USER_DEFINED

doc.buffer.subtype(bson.BSON_BINARY_SUBTYPE_UUID);

Converts this buffer for storage in MongoDB, including subtype

Converts this buffer to its Binary type representation.

SubTypes:

const bson = require('bson')
bson.BSON_BINARY_SUBTYPE_DEFAULT
bson.BSON_BINARY_SUBTYPE_FUNCTION
bson.BSON_BINARY_SUBTYPE_BYTE_ARRAY
bson.BSON_BINARY_SUBTYPE_UUID
bson.BSON_BINARY_SUBTYPE_MD5
bson.BSON_BINARY_SUBTYPE_USER_DEFINED
doc.buffer.toObject(bson.BSON_BINARY_SUBTYPE_USER_DEFINED);

Converts this buffer to a UUID. Throws an error if subtype is not 4.

Writes the buffer.
