public interface BinaryEntry

extends InvocableMap.Entry

Map.Entry that internally stores both key and value in a Binary format and uses an underlying Serializer to convert it to and from an Object view.

Method Detail

getBinaryKey

Binary getBinaryKey()

Return a raw binary key for this entry.

Returns:

a raw binary key for this entry

getBinaryValue

Binary getBinaryValue()

Return a raw binary value for this entry.

Returns:

a raw binary value for this entry; null if the value does not exist

getSerializer

Serializer getSerializer()

Return a Serializer that is used to serialize/deserialize this entry.

Returns:

a Serializer that is used to serialize/deserialize this entry

getContext

BackingMapManagerContext getContext()

Return the context this entry operates within.

Returns:

the BackingMapManagerContext for this entry

updateBinaryValue

void updateBinaryValue(Binary binValue)

Update the binary value for this entry. <p/> 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);
 

Parameters:

binValue - a raw binary value to for this entry or null

getOriginalValue

Object getOriginalValue()

Return an original value for this entry.

Returns:

an original value for this entry

Since:

Coherence 3.6

getOriginalBinaryValue

Binary getOriginalBinaryValue()

Return a raw original binary value for this entry.

Returns:

a raw original binary value for this entry; null if the original value did not exist

Since:

Coherence 3.6

getBackingMap

Map getBackingMap()

Obtain a reference to the backing map that this Entry corresponds to. The returned Map should be used in a read-only manner.

Returns:

the backing map reference; null if the entry does not have any backing map association

Since:

Coherence 3.6
