Method Detail

getSerializerByName

public TypedValueSerializer<?> getSerializerByName(java.lang.String serializerName)

Specified by:

getSerializerByName in interface VariableSerializers

Returns:

the serializer for the given serializerName name. Returns null if no type was found with the name.

findSerializerForValue

public TypedValueSerializer<?> findSerializerForValue(TypedValue value,
                                                      VariableSerializerFactory fallBackSerializerFactory)

Description copied from interface: VariableSerializers

Selects the TypedValueSerializer which should be used for persisting a VariableValue.

Specified by:

findSerializerForValue in interface VariableSerializers

Parameters:

value - the value to persist

fallBackSerializerFactory - a factory to build a fallback serializer in case no suiting serializer can be determined. If this factory is not able to build serializer either, an exception is thrown. May be null

Returns:

the VariableValueserializer selected for persisting the value or 'null' in case no serializer can be found

findSerializerForValue

public TypedValueSerializer<?> findSerializerForValue(TypedValue value)

Description copied from interface: VariableSerializers

Same as calling VariableSerializers.findSerializerForValue(TypedValue, VariableSerializerFactory) with no fallback serializer factory.

Specified by:

findSerializerForValue in interface VariableSerializers

addSerializer

public DefaultVariableSerializers addSerializer(TypedValueSerializer<?> serializer)

Specified by:

addSerializer in interface VariableSerializers

addSerializer

public DefaultVariableSerializers addSerializer(TypedValueSerializer<?> serializer,
                                                int index)

Description copied from interface: VariableSerializers

Add type at the given index. The index is used when finding a serializer for a VariableValue. When different serializers can store a specific variable value, the one with the smallest index will be used.

Specified by:

addSerializer in interface VariableSerializers

setSerializerList

public void setSerializerList(java.util.List<TypedValueSerializer<?>> serializerList)

getSerializerIndex

public int getSerializerIndex(TypedValueSerializer<?> serializer)

Specified by:

getSerializerIndex in interface VariableSerializers

getSerializerIndexByName

public int getSerializerIndexByName(java.lang.String serializerName)

Specified by:

getSerializerIndexByName in interface VariableSerializers

removeSerializer

public VariableSerializers removeSerializer(TypedValueSerializer<?> serializer)

Specified by:

removeSerializer in interface VariableSerializers

join

public VariableSerializers join(VariableSerializers other)

Description copied from interface: VariableSerializers

Merges two VariableSerializers instances into one. Implementations may apply different merging strategies.

Specified by:

join in interface VariableSerializers

getSerializers

public java.util.List<TypedValueSerializer<?>> getSerializers()

Description copied from interface: VariableSerializers

Returns the serializers as a list in the order of their indices.

Specified by:

getSerializers in interface VariableSerializers
