org.jboss.logmanager.ext.formatters.StructuredFormatter

Direct Known Subclasses:

JsonFormatter, XmlFormatter

public abstract class StructuredFormatter
extends org.jboss.logmanager.ExtFormatter

An abstract class that uses a generator to help generate structured data from a record.

Note that including details can be expensive in terms of calculating the caller.

By default the appending EOL (\n) is set to true.

createGenerator

protected abstract StructuredFormatter.Generator createGenerator(Writer writer)
                                                          throws Exception

Creates the generator used to create the structured data.

Returns:

the generator to use

Throws:

Exception - if an error occurs creating the generator

before

protected void before(StructuredFormatter.Generator generator,
                      org.jboss.logmanager.ExtLogRecord record)
               throws Exception

Invoked before the structured data is added to the generator.

Parameters:

generator - the generator to use

record - the log record

Throws:

Exception

after

protected void after(StructuredFormatter.Generator generator,
                     org.jboss.logmanager.ExtLogRecord record)
              throws Exception

Invoked after the structured data has been added to the generator.

Parameters:

generator - the generator to use

record - the log record

Throws:

Exception

getKey

protected final String getKey(StructuredFormatter.Key defaultKey)

Checks to see if the key should be overridden.

Parameters:

defaultKey - the default key

Returns:

the overridden key or the default key if no override exists

format

public String format(org.jboss.logmanager.ExtLogRecord record)

Specified by:

format in class org.jboss.logmanager.ExtFormatter

isAppendEndOfLine

public boolean isAppendEndOfLine()

Indicates whether or not an EOL (\n) character will appended to the formatted message.

Returns:

true to append the EOL character, otherwise false

setAppendEndOfLine

public void setAppendEndOfLine(boolean addEolChar)

Set whether or not an EOL (\n) character will appended to the formatted message.

Parameters:

addEolChar - true to append the EOL character, otherwise false

getMetaData

public String getMetaData()

Returns the value set for meta data.

The value is a string where key/value pairs are separated by commas. The key and value are separated by an equal sign.

Returns:

the meta data string or null if one was not set

See Also:

ValueParser.stringToMap(String)

setMetaData

public void setMetaData(String metaData)

Sets the meta data to use in the structured format.

The value is a string where key/value pairs are separated by commas. The key and value are separated by an equal sign.

Parameters:

metaData - the meta data to set or null to not format any meta data

See Also:

ValueParser.stringToMap(String)

getDateFormat

public String getDateFormat()

Gets the current date format.

Returns:

the current date format

setDateFormat

public void setDateFormat(String pattern)

Sets the pattern to use when formatting the date. The pattern must be a valid SimpleDateFormat pattern.

If the pattern is null a default pattern will be used.

Parameters:

pattern - the pattern to use

isPrintDetails

public boolean isPrintDetails()

Indicates whether or not details should be printed.

Returns:

true if details should be printed, otherwise false

setPrintDetails

public void setPrintDetails(boolean printDetails)

Sets whether or not details should be printed.

Printing the details can be expensive as the values are retrieved from the caller. The details include the source class name, source file name, source method name and source line number.

Parameters:

printDetails - true if details should be printed
