Method Detail

getLogger

Logger getLogger(String name)

Returns a logger which is backed by a logger from the log provider.

Note: this should never be null

Parameters:

name - the name of the logger

Returns:

a logger for the log provider logger.

clearMdc

void clearMdc()

Removes all entries from the message diagnostics context.

putMdc

Object putMdc(String key,
              Object value)

Puts the value onto the message diagnostics context.

Parameters:

key - the key for the value

value - the value

Returns:

the previous value set or null if no value was set

getMdc

Object getMdc(String key)

Returns the value for the key on the message diagnostics context or null if no value was found.

Parameters:

key - the key to lookup the value for

Returns:

the value or null if not found

removeMdc

void removeMdc(String key)

Removes the value from the message diagnostics context.

Parameters:

key - the key of the value to remove

getMdcMap

Map<String,Object> getMdcMap()

Returns the map from the context.

Note that in most implementations this is an expensive operation and should be used sparingly.

Returns:

the map from the context or an empty map if the context is null

clearNdc

void clearNdc()

Clears the nested diagnostics context.

getNdc

String getNdc()

Retrieves the current values set for the nested diagnostics context.

Returns:

the current value set or null if no value was set

getNdcDepth

int getNdcDepth()

The current depth of the nested diagnostics context.

Returns:

the current depth of the stack

popNdc

String popNdc()

Pops top value from the stack and returns it.

Returns:

the top value from the stack or an empty string if no value was set

peekNdc

String peekNdc()

Peeks at the top value from the stack and returns it.

Returns:

the value or an empty string

pushNdc

void pushNdc(String message)

Pushes a value to the nested diagnostics context stack.

Parameters:

message - the message to push

setNdcMaxDepth

void setNdcMaxDepth(int maxDepth)

Sets maximum depth of the stack removing any entries below the maximum depth.

Parameters:

maxDepth - the maximum depth to set
