Class TemporalAttributeStorageProxy

java.lang.Object
  net.sf.jtemporal.spi.TemporalAttributeStorageProxy

All Implemented Interfaces:: TemporalAttributeStorage

public abstract class TemporalAttributeStorageProxy
extends java.lang.Object
implements TemporalAttributeStorage
extends java.lang.Object
implements TemporalAttributeStorage

A skeletont for building a proxy. Delegates all the calls to a given instance of TemporalAttributeStorage. You can interecept any delegate call by overriding the method.
It has been marked as abstract, even there is nothing abstract inside, since it does not make sense to use it without subclassing it.

Constructor Summary
`TemporalAttributeStorageProxy(TemporalAttributeStorage storage)` Creates a new instance on top of an exisitng storage.

Method Summary
`void`	`beginAtomicOperation()` Tells the storage that the JTemporal client is calling a method that can result in multiples updates in the storage.
`void`	`clear()` Removes all the stored mappings.
`boolean`	`containsValue(java.lang.Object value)` Returns `true` if this map maps one or more Periods to the specified value.
`boolean`	`containsValue(java.lang.Object value, Period range)` Returns `true` if this map maps one or more Periods to the specified value, during the specified period.
`void`	`endAtomicOperation()` Tells the storage that an atomic operation has finished.
`CloseableIterator`	`entryIterator()` Iterates over all the entries of the storage.
`CloseableIterator`	`entryIterator(Period p)` Iterates over all the entries of the storage that intersects the period P.
`Period`	`firstPeriod()` Returns the first (lowest) period currently in this storage.
`Period`	`firstPeriod(Period p)` Returns the first (lowest) period currently in this storage, that intersects the given period.
`TimedObject`	`getEntry(Instant instant)` Returns the entry valid at the given instant, if any is found.
`TimedObject`	`getEntryEndingAt(Instant instant)` Returns the entry finishing exactly at the given instant, if any is found.
`TimedObject`	`getEntryStartingAt(Instant instant)` Returns the entry starting exactly at the given instant, if any is found.
`Period`	`getPeriod(Instant instant)` Returns the period that encloses the given instant, if any is found.
`java.lang.Object`	`getValue(Instant instant)` Returns the value to which this map maps the specified Instant.
`boolean`	`isEmpty()` Returns `true` if this storage does not contain objects.
`boolean`	`isEmpty(Period p)` Returns `true` if this storage does not contain objects intersecting the given period.
`Period`	`lastPeriod()` Returns the last (highest) period currently in this storage.
`Period`	`lastPeriod(Period p)` Returns the last (highest) period currently in this storage, that intersects the given period.
`CloseableIterator`	`periodIterator()` Iterates over all the periods of the storage.
`CloseableIterator`	`periodIterator(Period p)` Iterates over all the periods of the storage that intersects the period P.
`void`	`put(Period p, java.lang.Object value)` Stores a mapping (entry, tuple, row) composed by period and value.
`void`	`removeEntry(Period p)` Removes an entry composed by period and value previously stored.
`int`	`removeRange(Period range)` Removes all the entries whose period indersects the given period.
`int`	`size()` Returns the number of Period-value mappings in this map.
`int`	`size(Period p)` Returns the number of Period-value mappings in this map, for the given priod.
