Class DefaultJohnsonConfig

java.lang.Object

com.atlassian.johnson.config.DefaultJohnsonConfig

All Implemented Interfaces:

JohnsonConfig

public final class DefaultJohnsonConfig
extends Object
implements JohnsonConfig

A default implementation of JohnsonConfig which may be used as a failsafe when no other configuration is available.

All URIs are ignored by this implementation. All collection-returning properties are implemented to return empty, immutable collections. All other methods generally return null, except for:

• SetupConfig is provided by DefaultSetupConfig
• ContainerFactory is provided by DefaultContainerFactory

This class cannot be instantiated. A single, immutable instance is available via getInstance().

Since:

2.0

Method Detail

getInstance

@Nonnull
public static JohnsonConfig getInstance()

Retrieves the immutable singleton instance of the default configuration.

Returns:

the default configuration singleton

getApplicationEventChecks

@Nonnull
public List<ApplicationEventCheck> getApplicationEventChecks()

Always empty but non-null.

Specified by:

getApplicationEventChecks in interface JohnsonConfig

Returns:

an empty list

getContainerFactory

@Nonnull
public ContainerFactory getContainerFactory()

Always an instance of DefaultContainerFactory.

Specified by:

getContainerFactory in interface JohnsonConfig

Returns:

a default container factory

getErrorPath

@Nonnull
public String getErrorPath()

Always "/unavailable". isIgnoredPath(String) always returns true, so this path should never be accessed; Johnson processing is bypassed for all paths.

Specified by:

getErrorPath in interface JohnsonConfig

Returns:

"/unavailable"

getEventCheck

public EventCheck getEventCheck(int id)

Always null.

Specified by:

getEventCheck in interface JohnsonConfig

Parameters:

id - ignored

Returns:

null

getEventChecks

@Nonnull
public List<EventCheck> getEventChecks()

Always empty but non-null.

Specified by:

getEventChecks in interface JohnsonConfig

Returns:

an empty list

getEventLevel

public EventLevel getEventLevel(@Nonnull
                                String level)

Always null.

Specified by:

getEventLevel in interface JohnsonConfig

Parameters:

level - ignored

Returns:

null

getEventType

public EventType getEventType(@Nonnull
                              String type)

Always null.

Specified by:

getEventType in interface JohnsonConfig

Parameters:

type - ignored

Returns:

null

getIgnorePaths

@Nonnull
public List<String> getIgnorePaths()

Always empty but non-null.

Specified by:

getIgnorePaths in interface JohnsonConfig

Returns:

an empty list

getParams

@Nonnull
public Map<String,String> getParams()

Always empty but non-null.

Specified by:

getParams in interface JohnsonConfig

Returns:

an empty map

getRequestEventChecks

@Nonnull
public List<RequestEventCheck> getRequestEventChecks()

Always empty but non-null.

Specified by:

getRequestEventChecks in interface JohnsonConfig

Returns:

an empty list

getSetupConfig

@Nonnull
public SetupConfig getSetupConfig()

Always an instance of DefaultSetupConfig.

Specified by:

getSetupConfig in interface JohnsonConfig

getSetupPath

@Nonnull
public String getSetupPath()

Always "/setup". The default configuration is always setup, so this path should never be accessed.

Specified by:

getSetupPath in interface JohnsonConfig

Returns:

"/setup"

isIgnoredPath

public boolean isIgnoredPath(@Nonnull
                             String uri)

Always true. This has the net effect of disabling Johnson, because all URIs included for filtering will be ignored and events will not be processed for them.

Specified by:

isIgnoredPath in interface JohnsonConfig

Parameters:

uri - ignored

Returns:

true
