Interface Pipe<T>

Type Parameters:

T - The data type of the Pipe operation

All Known Subinterfaces:

LoaderPipe<T>

All Known Implementing Classes:

LoaderAdapter, RestAdapter, SupportLoaderAdapter

public interface Pipe<T>

A Pipe represents a server connection. An object of this class is responsible to communicate with the server in order to perform read/write operations.

Method Summary

com.google.gson.Gson	getGson() Returns the GSON serializer used to serialized instances of objects.
PipeHandler<T>	getHandler() Returns the instance which is responsible for handling read, save, and remove.
Class<T>	getKlass()
PipeType	getType() Returns the connection type of this Pipe object (e.g.
URL	getUrl() Returns the URL to which this Pipe object points.
void	read(Callback<List<T>> callback) Sends a signal to the Pipe to read its data and return it via the callback.
void	readWithFilter(ReadFilter filter, Callback<List<T>> callback) Reads all the data from the underlying server connection.
void	remove(String id, Callback<Void> callback) Removes an object from the underlying server connection.
void	save(T item, Callback<T> callback) Saves or updates a given object on the server.

Method Detail

getType

PipeType getType()

Returns the connection type of this Pipe object (e.g. REST).

Returns:

the connection type

getUrl

URL getUrl()

Returns the URL to which this Pipe object points.

Returns:

the endpoint URL

read

void read(Callback<List<T>> callback)

Sends a signal to the Pipe to read its data and return it via the callback.

Parameters:

callback - The callback for consuming the result from the Pipe invocation.

readWithFilter

void readWithFilter(ReadFilter filter,
                    Callback<List<T>> callback)

Reads all the data from the underlying server connection.

Parameters:

callback - The callback for consuming the result from the Pipe invocation.

filter - a ReadFilter for performing pagination and querying.

save

void save(T item,
          Callback<T> callback)

Saves or updates a given object on the server.

Parameters:

item - the item to save or update

callback - The callback for consuming the result from the Pipe invocation.

remove

void remove(String id,
            Callback<Void> callback)

Removes an object from the underlying server connection. The given key argument is used as the objects ID.

Parameters:

id - representing the ‘id’ of the object to be removed

callback - The callback for consuming the result from the Pipe invocation.

getGson

com.google.gson.Gson getGson()

Returns the GSON serializer used to serialized instances of objects.

Returns:

the gson instance servicing this pipe.

getKlass

Class<T> getKlass()

Returns:

the class which travels on this pipe

getHandler

PipeHandler<T> getHandler()

Returns the instance which is responsible for handling read, save, and remove.

Returns:

the handler performing operations for this Pipe. May be the Pipe itself.
