Method Summary

All Methods Static Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`boolean`	`containsChecksumValue(ChecksumAlgorithm algorithm)`	Returns `true` if the store contains a checksum value for the given algorithm, `false` otherwise.
`static PayloadChecksumStore`	`create()`	Returns the default implementation of this interface.
`byte[]`	`getChecksumValue(ChecksumAlgorithm algorithm)`	Retrieve the stored checksum value for the given algorithm.
`byte[]`	`putChecksumValue(ChecksumAlgorithm algorithm, byte[] checksum)`	Store the checksum value computed using the given algorithm.

- Method Detail
  - putChecksumValue
```
byte[] putChecksumValue(ChecksumAlgorithm algorithm,
                        byte[] checksum)
```
    Store the checksum value computed using the given algorithm.
    
    Returns:
    
    The previous value stored for this algorithm or null if not present.
  - getChecksumValue
```
byte[] getChecksumValue(ChecksumAlgorithm algorithm)
```
    Retrieve the stored checksum value for the given algorithm.
    
    Returns:
    
    The checksum value for the given algorithm or null if not present.
  - containsChecksumValue
```
boolean containsChecksumValue(ChecksumAlgorithm algorithm)
```
    Returns true if the store contains a checksum value for the given algorithm, false otherwise.
  - create
```
static PayloadChecksumStore create()
```
    Returns the default implementation of this interface.
