Class TypeRegistry<U>

java.lang.Object

org.calrissian.mango.types.TypeRegistry<U>

All Implemented Interfaces:

Serializable

public class TypeRegistry<U>
extends Object
implements Serializable

The TypeRegistry is used as a means to register and easily utilize various encoding schemes to provide a simple mechanism to encode and decode from one Object type to another. The core the the TypeRegistry are the encoders which are loaded during initialization, and can be used to fully customize how data is encoded and decoded.

One of the core concepts with the TypeRegistry is the use of an alias. The use of an alias is used as a simple mechanism to identify which TypeEncoder should be used for decoding a value. Any value for an alias can be used on a TypeEncoder, with the the limitation that all TypeEncoders added to the TypeRegistry must be unique.

Method Detail

getAlias

public String getAlias(Object obj)

Gets registered alias for a provided object type. This is used to identify which TypeEncoder to use for decoding.

getClassAlias

public String getClassAlias(Class clazz)

Retrieves the registered alias for the provided Class.

encode

public U encode(Object value)

Encodes the given value using one of the registered TypeEncoders.

decode

public Object decode(String alias,
                     U value)

Decodes the given value using one of the registered TypeEncoders. The alias is used to determine which TypeEncoder will be used and shall correlate to the result of the getAlias() method for the original object.

getAllEncoders

public Collection<TypeEncoder<?,U>> getAllEncoders()

Returns all the registered TypeEncoders in the registry
