Class LimitedMemoryExchangeStore

java.lang.Object

com.predic8.membrane.core.exchangestore.AbstractExchangeStore

com.predic8.membrane.core.exchangestore.LimitedMemoryExchangeStore

All Implemented Interfaces:

ExchangeStore

public class LimitedMemoryExchangeStore
extends AbstractExchangeStore

Description

Stores exchange objects in-memory until a memory threshold is reached. When the threshold is reached and new exchanges arrive then old exchanges will be dropped (starting from oldest ascending) until the exchange can be stored. The LimitedMemoryExchangeStore is the default ExchangeStore Membrane uses.

Method Detail

snap

public void snap(AbstractExchange exc,
                 Interceptor.Flow flow)

Description copied from interface: ExchangeStore

Adds the current state of the exchange to the store. Implementations should take a snapshot of the current state of the request (or response) headers and register a body observer in which they will be called back as soon as the body has fully been received. If flow==REQUEST, the request is added. Elsewise, the response is added (if present).

cleanSnapshot

public <T extends AbstractExchange> T cleanSnapshot(T snapshot)

remove

public void remove(AbstractExchange exc)

removeAllExchanges

public void removeAllExchanges(Rule rule)

getExchanges

public AbstractExchange[] getExchanges(RuleKey ruleKey)

getNumberOfExchanges

public int getNumberOfExchanges(RuleKey ruleKey)

getStatistics

public StatisticCollector getStatistics(RuleKey key)

getAllExchanges

public Object[] getAllExchanges()

getAllExchangesAsList

public List<AbstractExchange> getAllExchangesAsList()

removeAllExchanges

public void removeAllExchanges(AbstractExchange[] candidates)

getExchangeById

public AbstractExchange getExchangeById(int id)

Specified by:

getExchangeById in interface ExchangeStore

Overrides:

getExchangeById in class AbstractExchangeStore

getClientStatistics

public List<? extends ClientStatistics> getClientStatistics()

Specified by:

getClientStatistics in interface ExchangeStore

Overrides:

getClientStatistics in class AbstractExchangeStore

getCurrentSize

public int getCurrentSize()

getOldestTimeResSent

public Long getOldestTimeResSent()

getMaxSize

public int getMaxSize()

Default

1000000

Description

Threshold limit in bytes until old exchanges are dropped.

Example

1048576(1Mb)

setMaxSize

public void setMaxSize(int maxSize)

getLastModified

public long getLastModified()

Specified by:

getLastModified in interface ExchangeStore

Overrides:

getLastModified in class AbstractExchangeStore

waitForModification

public void waitForModification(long lastKnownModification)
                         throws InterruptedException

Description copied from interface: ExchangeStore

Returns immediately if lastKnownModification is smaller than last known modification. Otherwise it waits until a modification occurs.

Specified by:

waitForModification in interface ExchangeStore

Overrides:

waitForModification in class AbstractExchangeStore

Throws:

InterruptedException

isNewAlgorithm

public boolean isNewAlgorithm()

setNewAlgorithm

public void setNewAlgorithm(boolean newAlgorithm)
