VersionedPut () | |
Construct a VersionedPut. | |
VersionedPut (Versionable::Handle hValue, bool fAllowInsert=false, bool fReturn=false) | |
Construct a VersionedPut 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. | |
virtual Object::Holder | processEntry (InvocableMap::Entry::Handle hEntry, Versionable::Holder ohValueNew, bool fInsert, bool fReturn) const |
Process the given entry. | |
Protected Attributes | |
FinalHandle < Versionable > | f_hValue |
Specifies the new value to update an entry with. | |
bool | m_fInsert |
Specifies whether or not an insert is allowed. | |
bool | m_fReturn |
Specifies whether or not a return value is required. |

) | [protected] |
Construct a VersionedPut 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.
This processor optionally returns the current value as a result of the invocation if it has not been updated (the versions did not match).
hValue | a value to update an entry with | |
fAllowInsert | specifies whether or not an insert should be allowed (no currently existing value) | |
fReturn | specifies whether or not the processor should return the current value in case it has not been updated |
