put(String key, byte[] value)
Associates the specified value with the specified key.

Public methods
put
public abstract byte[] put (String key,
byte[] value)
Associates the specified value with the specified key.
If a value already exists for that key, the old value is replaced.
This method may take several seconds to complete, so it should
only be called from a worker thread.
| Parameters |
|---|
key |
String: key with which the specified value is to be associated
This value cannot be null. |
value |
byte: value to be associated with the specified key
This value cannot be null. |
| Returns |
|---|
byte[] |
the previous value associated with key, or null if there was no mapping for key. |
remove
public abstract byte[] remove (String key)
Removes the mapping for the specified key.
This method may take several seconds to complete, so it should
only be called from a worker thread.
| Parameters |
|---|
key |
String: key whose mapping is to be removed
This value cannot be null. |
| Returns |
|---|
byte[] |
the previous value associated with key, or null if there was no mapping for key. |
