binKey
- the Binary keybinValue

public java.lang.Object setValue(java.lang.Object oValue)
setValue
in interface InvocableMap.Entry
setValue
in interface java.util.Map.Entry
setValue
in class BackingMapBinaryEntry
oValue
- the new value for this Entrypublic void updateBinaryValue(Binary binValue)
Passing a non-null binary is functionally equivalent to:
setValue(getContext().getValueFromInternalConverter().convert(binValue));Passing null value is functionally equivalent to removing the entry.
remove(false);
updateBinaryValue
in interface BinaryEntry
updateBinaryValue
in class BackingMapBinaryEntry
binValue
- new binary value to be stored in this entry or nullpublic ObservableMap getBackingMap()
Note: This method is a shortcut for the getBackingMapContext().getBackingMap()
call. As of Coherence 3.7, the returned type has been narrowed to ObservableMap.

Note: this method only has an effect only if the associated backing map implements the CacheMap

- the number of milliseconds until the entry will expire; pass CacheMap.EXPIRY_DEFAULT
to use the default expiry setting; pass CacheMap.EXPIRY_NEVER
