Reconstruction is recommended via the CRC32C.from static method.
Parameters:
| Name | Type | Default | Description |
|---|---|---|---|
initialValue |
0 |
An initial CRC32C value - a signed 32-bit integer. |
Methods
toBuffer()
Returns a Buffer representation of the CRC32C value
toJSON()
Returns a JSON-compatible, base64-encoded representation of the CRC32C value.
See JSON#stringify
toString()
Returns a base64-encoded representation of the CRC32C value.
See Object#toString
update(data)
Calculates a CRC32C from a provided buffer.
Implementation inspired from:

valueOf()
Returns the number representation of the CRC32C value as a signed 32-bit integer
See Object#valueOf
(static) from(value)
Generates a CRC32C from a variety of compatable types.
Note: strings are treated as input, not as file paths to read from.
