Constructor Description

Crc32Checksum()
Creates CRT Based Crc32 checksum if Crt classpath for Crc32 is loaded, else create Sdk Implemented Crc32.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`byte[]`	`getChecksumBytes()`	Returns the computed checksum in a byte array rather than the long provided by `Checksum.getValue()`.
`long`	`getValue()`
`void`	`mark(int readLimit)`	Allows marking a checksum for checksums that support the ability to mark and reset.
`void`	`reset()`

  - getChecksumBytes
```
public byte[] getChecksumBytes()
```
    Description copied from interface: SdkChecksum
    
    Returns the computed checksum in a byte array rather than the long provided by Checksum.getValue().
    
    Specified by:

    Returns:
    
    byte[] containing the checksum
  - mark
```
public void mark(int readLimit)
```
    Description copied from interface: SdkChecksum
