CatchProcessor

public CatchProcessor(List<Class<? extends Throwable>> exceptions,
                      org.apache.camel.Processor processor,
                      org.apache.camel.Predicate onWhen,

Method Detail

toString

public String toString()

Overrides:

toString in class org.apache.camel.support.processor.DelegateAsyncProcessor

getId

public String getId()

Specified by:

getId in interface org.apache.camel.spi.HasId

setId

public void setId(String id)

Specified by:

setId in interface org.apache.camel.spi.IdAware

getTraceLabel

public String getTraceLabel()

Specified by:

getTraceLabel in interface org.apache.camel.Traceable

process

public boolean process(org.apache.camel.Exchange exchange,
                       org.apache.camel.AsyncCallback callback)

Specified by:

process in interface org.apache.camel.AsyncProcessor

Overrides:

process in class org.apache.camel.support.processor.DelegateAsyncProcessor

catches

protected Throwable catches(org.apache.camel.Exchange exchange,
                            Throwable exception)

Returns with the exception that is caught by this processor. This method traverses exception causes, so sometimes the exception returned from this method might be one of causes of the parameter passed.

Parameters:

exchange - the current exchange

exception - the thrown exception

Returns:

Throwable that this processor catches. null if nothing matches.

getExceptions

public List<Class<? extends Throwable>> getExceptions()

matchesWhen

protected boolean matchesWhen(org.apache.camel.Exchange exchange)

Strategy method for matching the exception type with the current exchange.

This default implementation will match as:

• Always true if no when predicate on the exception type
• Otherwise the when predicate is matches against the current exchange

Parameters:

exchange - the current Exchange

Returns:

true if matched, false otherwise.
