com.grey.logging.Logger

com.grey.logging.LatinLogger

All Implemented Interfaces:

Direct Known Subclasses:

MTLatinLogger

public class LatinLogger
extends Logger

This logger optimises away some relatively expensive character handling by assuming the log messages are all 8-bit charsets, and can be mapped to 1-to-1 to a byte stream.
This assumption allows it to map the characters to bytes on a 1-to-1 basis, and write out a byte stream via the more efficient JDK OutputStream classes (that is, more efficient than the char-oriented java.io.Writer classes).

Technically this class is therefore not limited to messages in the Latin alphabets since Arabic, Cyrillic and even Thai have 8-bit charsets defined in the ISO-8859 family, but the more exotic character sets are more likely to be represented with Unicode, so 8-bit characters do tend to mean we're dealing with plain ASCII or the Latin members of the ISO-8859 family.
