Class AbstractPatternJsonProvider<Event extends ch.qos.logback.core.spi.DeferredProcessingAware>

java.lang.Object

ch.qos.logback.core.spi.ContextAwareBase

net.logstash.logback.composite.AbstractJsonProvider<Event>

net.logstash.logback.composite.AbstractPatternJsonProvider<Event>

Type Parameters:

Event - type of event (ILoggingEvent or IAccessEvent).

All Implemented Interfaces:

ch.qos.logback.core.spi.ContextAware, ch.qos.logback.core.spi.LifeCycle, JsonFactoryAware, JsonProvider<Event>

Direct Known Subclasses:

AccessEventPatternJsonProvider, LoggingEventPatternJsonProvider

public abstract class AbstractPatternJsonProvider<Event extends ch.qos.logback.core.spi.DeferredProcessingAware>
extends AbstractJsonProvider<Event>
implements JsonFactoryAware

Transforms an string containing patterns understood by PatternLayouts into JSON output. Delegates most of the work to the AbstractJsonPatternParser that is to parse the pattern specified. Subclasses must implement createParser() method so it returns parser valid for a specified event class.

             throws IOException

Description copied from interface: JsonProvider

Writes information about the event, to the given generator. When called, the generator is assumed to be within a JSON object context (i.e. this provider should write fields and their values to the generator). Upon return, the generator should be within the same JSON object context.

Specified by:

writeTo in interface JsonProvider<Event extends ch.qos.logback.core.spi.DeferredProcessingAware>

Throws:

IOException
