getType in interface TypedValueSerializer<T extends TypedValue>

Returns:

the VariableType supported

getSerializationDataformat

public java.lang.String getSerializationDataformat()

Specified by:

getSerializationDataformat in interface TypedValueSerializer<T extends TypedValue>

Returns:

the dataformat used by the serializer or null if this is not an object serializer

canHandle

public boolean canHandle(TypedValue value)

Description copied from interface: TypedValueSerializer

Used for auto-detecting the value type of a variable. An implementation must return true if it is able to write values of the provided type.

Specified by:

canHandle in interface TypedValueSerializer<T extends TypedValue>

Parameters:

value - the value

Returns:

true if this TypedValueSerializer is able to handle the provided value

canWriteValue

protected abstract boolean canWriteValue(TypedValue value)

isMutableValue

public boolean isMutableValue(T typedValue)

Specified by:

isMutableValue in interface TypedValueSerializer<T extends TypedValue>

Returns:

whether values serialized by this serializer can be mutable and should be re-serialized if changed
