com.tangosol.util.processor.VersionedPutAll
public class VersionedPutAll
VersionedPutAll is an EntryProcessor that assumes that entry values
implement Versionable
interface and performs an
Entry.setValue
operation only for entries whose versions match to versions
of the corresponding current values. In case of the match, the
VersionedPutAll will increment the version indicator before each value is
updated.

Field Summary | |
---|---|
protected boolean |
m_fInsert
Specifies whether or not an insert is allowed. |
protected boolean |
m_fReturn
Specifies whether or not a return value is required. |
protected Map |
m_map
Specifies the map of new values. |
Constructor Summary | |
---|---|
VersionedPutAll()
Default constructor (necessary for the ExternalizableLite interface). |
|
VersionedPutAll(Map map)
Construct a VersionedPutAll processor that updates an entry with a new value if and only if the version of the new value matches to the version of the current entry's value (which must exist). |
|
VersionedPutAll(Map map,
boolean fAllowInsert,
boolean fReturn)
Construct a VersionedPutAll processor that updates an entry with a new value if and only if the version of the new value matches to the version of the current entry's value (which must exist). |
Method Summary | |
---|---|
boolean |
equals(Object o)
Compare the VersionedPutAll with another object to determine equality. |
int |
hashCode()
Determine a hash value for the VersionedPutAll object according to the general Object.hashCode() contract. |
Object |
process(InvocableMap.Entry entry)
Process a Map.Entry object. |
void |
readExternal(DataInput in)
Restore the contents of this object by loading the object's state from the passed DataInput object. |
void |
readExternal(PofReader in)
Restore the contents of a user type instance by reading its state using the specified PofReader object. |
String |
toString()
Return a human-readable description for this VersionedPutAll. |
void |
writeExternal(DataOutput out)
Save the contents of this object by storing the object's state into the passed DataOutput object. |
void |
writeExternal(PofWriter out)
Save the contents of a POF user type instance by writing its state using the specified PofWriter object. |
