getCopyOfContextMap

public Map<String,String> getCopyOfContextMap()

Return a copy of the current thread's context map. null is returned if

• The MDC functionality is disabled, c.f. setEnable, or
• "return null when empty" is enabled, c.f. setReturnNullCopyWhenMdcNotSet, and put has not been called.

Specified by:

getCopyOfContextMap in interface org.slf4j.spi.MDCAdapter

Overrides:

getCopyOfContextMap in class org.slf4j.helpers.BasicMDCAdapter

Returns:

A copy of the current thread's context map.

setContextMap

public void setContextMap(Map<String,String> contextMap)

Specified by:

setContextMap in interface org.slf4j.spi.MDCAdapter

Overrides:

setContextMap in class org.slf4j.helpers.BasicMDCAdapter

setEnable

public void setEnable(boolean enable)

Enable the MDC functionality for all threads.

Parameters:

enable - Whether to enable the MDC functionality. The default value is true.

setInherit

public void setInherit(boolean inherit)

Define whether child threads inherit a copy of the MDC from its parent thread. Note that the copy is taken when the Thread is constructed. This affects all threads.

Parameters:

inherit - Whether to enable inheritance. The default value is false.

setAllowNullValues

public void setAllowNullValues(boolean allowNullValues)

Define whether null values are allowed in the MDC. This affects all threads.

Parameters:

allowNullValues - Whether to allow nulls. The default value is true.

setReturnNullCopyWhenMdcNotSet

public void setReturnNullCopyWhenMdcNotSet(boolean returnNullCopyWhenMdcNotSet)

Define whether getCopyOfContextMap() returns null when no values have been set. This affects all threads.

Parameters:

returnNullCopyWhenMdcNotSet - Whether to return null. The default value is false. If false, an empty map is returned instead.

getEnable

public boolean getEnable()

Whether the MDC functionality is enabled.

Returns:

Whether the MDC functionality is enabled.

getInherit

public boolean getInherit()

Whether child threads inherit a copy of the MDC from its parent thread.

Returns:

Whether inheritance is enabled.

getAllowNullValues

public boolean getAllowNullValues()

Whether null values are allowed in the MDC.

Returns:

Whether nulls are allowed.

getReturnNullCopyWhenMdcNotSet

public boolean getReturnNullCopyWhenMdcNotSet()

Whether getCopyOfContextMap() returns null when no values have been set.

Returns:

Whether to return null.

restoreOptions

public void restoreOptions()

Reset the options to values defined by the static configuration. This undoes to changes made using setEnable(boolean), setInherit(boolean), setAllowNullValues(boolean), and setReturnNullCopyWhenMdcNotSet(boolean).

getInstance

public static TestMDCAdapter getInstance()

Access the current MDC adapter. Used to call the option setting methods.
