Class ThreadContextDataInjector

java.lang.Object

org.apache.logging.log4j.core.impl.ThreadContextDataInjector

public class ThreadContextDataInjector
extends java.lang.Object

ThreadContextDataInjector contains a number of strategies for copying key-value pairs from the various ThreadContext map implementations into a StringMap. In the case of duplicate keys, thread context values overwrite configuration Property values.

These are the default ContextDataInjector objects returned by the ContextDataInjectorFactory.

Since:

2.7

Modifier and Type	Class	Description
static class	ThreadContextDataInjector.ForCopyOnWriteThreadContextMap	The ContextDataInjector used when the ThreadContextMap implementation is a copy-on-write StringMap-based data structure.
static class	ThreadContextDataInjector.ForDefaultThreadContextMap	Default ContextDataInjector for the legacy Map<String, String>-based ThreadContext (which is also the ThreadContext implementation used for web applications).
static class	ThreadContextDataInjector.ForGarbageFreeThreadContextMap	The ContextDataInjector used when the ThreadContextMap implementation is a garbage-free StringMap-based data structure.

Method Detail

initServiceProviders

@Deprecated
public static void initServiceProviders()

Deprecated.

no-op

Previously this method allowed ContextDataProviders to be loaded eagerly, now they are loaded when this class is initialized.

getServiceProviders

private static java.util.List<ContextDataProvider> getServiceProviders()

copyProperties

public static void copyProperties(java.util.List<Property> properties,
                                  StringMap result)

Copies key-value pairs from the specified property list into the specified StringMap.

Parameters:

properties - list of configuration properties, may be null

result - the StringMap object to add the key-values to. Must be non-null.
