RpcCRC32Checksum (p4java 2024.1.2612262 API)

java.lang.Object
- java.util.zip.CRC32
- - com.perforce.p4java.impl.mapbased.rpc.sys.RpcCRC32Checksum

All Implemented Interfaces:

java.util.zip.Checksum
```
public class RpcCRC32Checksum
extends java.util.zip.CRC32
```
Provides a wrapper to the basic Java CRC32 to allow us to use the JZlib pure Java implementation of the CRC32 checksum from RFC1952.
This avoids the basic Java CRC32's JNI overhead for certain uses of checksumming where many small pieces of data are checksummed in succession.
