Interface GluonObservable

All Known Implementing Classes:

GluonObservableList, GluonObservableObject

public interface GluonObservable

This is the common interface for both GluonObservableObject and GluonObservableList. All operations on the DataProvider class happen in an asynchronous background thread. This interface can therefor be used to get information about the current state of the observable entity while the operation is running as well as the final state of the entity when the operation has completed.

Property Summary

Type	Property and Description
javafx.beans.property.ReadOnlyObjectProperty<java.lang.Throwable>	exception Holds the exception that was thrown when a synchronization operation failed.
javafx.beans.property.ReadOnlyBooleanProperty	initialized A boolean property that is true when the observable has been initialized successfully after its initial retrieval.
javafx.beans.property.ReadOnlyObjectProperty<ConnectState>	state Holds the current state of this observable.

Method Summary

Modifier and Type	Method and Description
javafx.beans.property.ReadOnlyObjectProperty<java.lang.Throwable>	exceptionProperty() Holds the exception that was thrown when a synchronization operation failed.
java.lang.Throwable	getException() In case an exception occurred during processing, this method will return the exception.
ConnectState	getState() Return the current state of this observable.
javafx.beans.property.ReadOnlyBooleanProperty	initializedProperty() A boolean property that is true when the observable has been initialized successfully after its initial retrieval.
boolean	isInitialized() Return the initialized state of this observable.
javafx.beans.property.ReadOnlyObjectProperty<ConnectState>	stateProperty() Holds the current state of this observable.

Property Detail

initialized

javafx.beans.property.ReadOnlyBooleanProperty initializedProperty

A boolean property that is true when the observable has been initialized successfully after its initial retrieval.

See Also:

isInitialized()

state

javafx.beans.property.ReadOnlyObjectProperty<ConnectState> stateProperty

Holds the current state of this observable. This property can be used to listen for changes in the synchronization process.

See Also:

getState()

exception

javafx.beans.property.ReadOnlyObjectProperty<java.lang.Throwable> exceptionProperty

Holds the exception that was thrown when a synchronization operation failed.

getException()

Method Detail

isInitialized

boolean isInitialized()

Return the initialized state of this observable.

Returns:

true when the observable is initialized; false otherwise.

initializedProperty

javafx.beans.property.ReadOnlyBooleanProperty initializedProperty()

A boolean property that is true when the observable has been initialized successfully after its initial retrieval.

See Also:

isInitialized()

getState

ConnectState getState()

Return the current state of this observable.

Returns:

the current state

stateProperty

javafx.beans.property.ReadOnlyObjectProperty<ConnectState> stateProperty()

Holds the current state of this observable. This property can be used to listen for changes in the synchronization process.

See Also:

getState()

getException

java.lang.Throwable getException()

In case an exception occurred during processing, this method will return the exception. Otherwise, null will be returned.

Returns:

the exception, if one has occurred; otherwise null.

exceptionProperty

javafx.beans.property.ReadOnlyObjectProperty<java.lang.Throwable> exceptionProperty()

Holds the exception that was thrown when a synchronization operation failed.
