Constructor Details

LoggableKeysAndValuesImpl

public LoggableKeysAndValuesImpl(@Nullable
 Object... keyValues)

Create an instance with the given message and a sequence of key-value pairs. This will throw an IllegalArgumentException if keyValues contains an odd number of elements.

Parameters:

keyValues - list

• addLogInfo(Object...)

Method Details

getLogInfo

@Nonnull
public Map<String,Object> getLogInfo()

Get the log information associated with this exception as a map.

Specified by:

getLogInfo in interface LoggableKeysAndValues<LoggableKeysAndValuesImpl>

Returns:

a single map with all log information

addLogInfo

@Nonnull
public LoggableKeysAndValuesImpl addLogInfo(@Nonnull
 String description,
 Object object)

Add a key/value pair to the log information. This will use the description given as the key and the object provided as the value.

Specified by:

addLogInfo in interface LoggableKeysAndValues<LoggableKeysAndValuesImpl>

Parameters:

description - description of the log info pair

object - value of the log info pair

Returns:

this LoggableException

addLogInfo

@Nonnull
public LoggableKeysAndValuesImpl addLogInfo(@Nonnull
 Object... keyValue)

Add a list of key/value pairs to the log information. This will treat the list of items as pairs to be added with every even element being a key and every odd element being a value (associated with the even key preceding it). So, for example, ["k0", "v0", "k1", "v1"] will add two pairs to the log info, one with key "k0" and value "v0" and one with key "k1" and value "v1". Note that this is the same format that is exported by exportLogInfo().

Specified by:

addLogInfo in interface LoggableKeysAndValues<LoggableKeysAndValuesImpl>

Parameters:

keyValue - flattened map of key-value pairs

Returns:

this LoggableException

Throws:

IllegalArgumentException - if keyValue has odd length

exportLogInfo

@Nonnull
public Object[] exportLogInfo()

Export the log information to a flattened array. This will flatten the map that would be returned by getLogInfo() into an array where every even element is a key within the map and every odd element is the value associated with the key before it. So, for example, {"k0:"v0", "k1":"v1"} would be flattened into ["k0", "v0", "k1", "v1"].

Specified by:

exportLogInfo in interface LoggableKeysAndValues<LoggableKeysAndValuesImpl>

Returns:

a flattened map of key-value pairs
