public class TimeTable
extends QueryTable
implements LiveTable

A TimeTable adds rows at a fixed interval with a single column named "Timestamp". To create a TimeTable, you should use the Database.timeTable(java.lang.String) family of methods.

Method Details

refresh

public void refresh()

Description copied from interface: LiveTable

Refresh this LiveTable.

Specified by:

refresh in interface LiveTable

destroy

protected void destroy()

Attempt to release (destructively when necessary) resources held by this object. This may render the object unusable for subsequent operations. Implementations should be sure to call super.destroy().

This is intended to only ever be used as a side effect of decreasing the reference count to 0.

Overrides:

destroy in class BaseTable

initializeTransientFieldsForLiveness

@VisibleForTesting public final void initializeTransientFieldsForLiveness()

Package-private for Serializable sub-classes to use in readObject only. Public to allow unit tests in another package to work around mock issues where the constructor is never invoked.

tryRetainReference

public final boolean tryRetainReference()

Description copied from interface: LivenessReferent

If this referent is "live", behave as LivenessReferent.retainReference() and return true. Otherwise, returns false rather than throwing an exception.

Specified by:

tryRetainReference in interface LivenessReferent

Returns:

True if this referent was retained, false otherwise

dropReference

public final void dropReference()

Description copied from interface: LivenessReferent

Drop a previously-retained reference to this referent.

Specified by:

dropReference in interface LivenessReferent

getWeakReference

public WeakReference<? extends LivenessReferent> getWeakReference()

Description copied from interface: LivenessReferent

Get a WeakReference to this referent. This may be cached, or newly created.

Specified by:

getWeakReference in interface LivenessReferent

Returns:

A new or cached reference to this referent

tryManage

public final boolean tryManage(@NotNull LivenessReferent referent)

Description copied from interface: LivenessManager

Attempt to add the specified referent to this manager.

Specified by:

tryManage in interface LivenessManager

Parameters:

referent - The referent to add

Returns:

Whether the referent was in fact added

onReferenceCountAtZero

protected final void onReferenceCountAtZero()

Description copied from class: ReferenceCounted

Callback method that will be invoked when the reference count returns to zero.

Specified by:

onReferenceCountAtZero in class ReferenceCounted
