Field Detail

• UNSET

  public static final java.lang.Object UNSET

  Deprecated. since 0.7.0 use UNCHANGED
  The onSuccess or onError functions can return this value to indicate that the sensor should not change.

• UNCHANGED

  public static final java.lang.Object UNCHANGED

  The onSuccess or onError functions can return this value to indicate that the sensor should not change.

• REMOVE

  public static final java.lang.Object REMOVE

  The onSuccess or onError functions can return this value to indicate that the sensor value should be removed (cf 'null', but useful in dynamic situations)

• NO_SENSOR

  public static final AttributeSensor<java.lang.Void> NO_SENSOR

  Indicates that no sensor is being used here. This sensor is suppressed, but is useful where you want to use the feeds with custom success/exception/failure functions which directly set multiple sensors, e.g. dynamically based on the poll response.

  See HttpPollConfig.forMultiple() and its usages. (It can work for any poll config, but conveniences have not been supplied for others.)

Constructor Detail

• FeedConfig

  public FeedConfig(AttributeSensor<T> sensor)

• FeedConfig

  public FeedConfig(FeedConfig<V,T,F> other)

Method Detail

• getSensor

  public AttributeSensor<T> getSensor()

• getCheckSuccess

  public com.google.common.base.Predicate<? super V> getCheckSuccess()

• getOnSuccess

  public com.google.common.base.Function<? super V,T> getOnSuccess()

• getOnFailure

  public com.google.common.base.Function<? super V,T> getOnFailure()

• getOnException

  public com.google.common.base.Function<? super java.lang.Exception,T> getOnException()

• checkSuccess

  public F checkSuccess(com.google.common.base.Predicate<? super V> val)

  sets the predicate used to check whether a feed run is successful

• checkSuccess

  public F checkSuccess(com.google.common.base.Function<? super V,java.lang.Boolean> val)

  as checkSuccess(Predicate)

• onSuccess

  public F onSuccess(com.google.common.base.Function<? super V,T> val)

• setOnSuccess

  public F setOnSuccess(T val)

• onFailure

  public F onFailure(com.google.common.base.Function<? super V,T> val)

  a failure is when the connection is fine (no exception) but the other end returns a result object V which the feed can tell indicates a failure (e.g. HTTP code 404)

• setOnFailure

  public F setOnFailure(T val)

• onResult

  public F onResult(com.google.common.base.Function<? super V,T> val)

  registers a callback to be used onSuccess(Function) and onFailure(Function), i.e. whenever a result comes back, but not in case of exceptions being thrown (ie problems communicating)

• setOnResult

  public F setOnResult(T val)

• onException

  public F onException(com.google.common.base.Function<? super java.lang.Exception,T> val)

  an exception is when there is an error in the communication

• setOnException

  public F setOnException(T val)

• onFailureOrException

  public F onFailureOrException(com.google.common.base.Function<java.lang.Object,T> val)

  convenience for indicating a behaviour to occur for both onException(Function) (error connecting) and onFailure(Function) (successful communication but failure report from remote end)

• setOnFailureOrException

  public F setOnFailureOrException(T val)

• hasSuccessHandler

  public boolean hasSuccessHandler()

• hasFailureHandler

  public boolean hasFailureHandler()

• hasExceptionHandler

  public boolean hasExceptionHandler()

• hasCheckSuccessHandler

  public boolean hasCheckSuccessHandler()
