	TJwLogServerImpl	This is class TJwLogServerImpl.
	TJwLogWriter	TJwLogWriter defines a default and base class for xml write operations and other util functions. Overwrite this class and specify its class type to CreateLogServer for changed behavior.

Constants

Name	Description
IID_JwWriterCLASS	This is constant IID_JwWriterCLASS.

Enumerations

	Name	Description
	TJwEnterType	TJwEnterType defines an enter/leave attribute type
	TJwLogType	TJwLogType defines log tag attribute types
	TJwSignalType	TJwSignalType defines a signal attribute type
	TJwXMLAttrTag	TJwXMLAttrTag defines known xml tag attributes
	TJwXMLEventType	This is record TJwXMLEventType.
	TJwXMLLogTag	This is record TJwXMLLogTag.
	TJwXMLTag	TJwXMLTag defines known XML tag names

Functions

	Name	Description
	CreateLogServer	CreateLogServer creates a new log server that can hold several log clients (IJwLogClient). A log sever creates a new logprocess tag and closes it if it is destroyed. It saves each xml tag into a new string list item in parameter Elements. This behavior can be overwritten by using a non default WriterClass (TJwLogWriterClass)
	Exception	Exception creates an exception information log entry.
	Exception	Exception creates an exception information log entry with log source information.
	GetEventTypesEnabled	This is function GetEventTypesEnabled.
	Log	Log creates an ordinary log entry with log source information.
	Log	Log creates an ordinary log entry.
	Memory	Memory creates a memory information log entry. Application can log allocations and deallocations of memory for leak search.
	Memory	Memory creates a memory information log entry with log source information. Application can log allocations and deallocations of memory for leak search.
	SetEventTypes	SetEventTypes sets the type of events which are logged of this log client
	SetEventTypesEnabled	SetEventTypesEnabled enables or disables logging. It just does not write output.
	Signal	Signal creates a signal log entry. A signal log entries is used for communcation logging. Threads or processes may use events to signal special events.

	IJwLogClient	IJwLogClient defines an interface for a log client. Use IJwLogServer.Connect to create an instance of this interface. Each log function is multi thread safe. Different log calls in different threads will wait for each other.
	IJwLogServer	This is class IJwLogServer.
	IJwWriterClass	This is class IJwWriterClass.

Records

	Name	Description
	TJwEventType	This is record TJwEventType.
	TJwXMLAttribute	TJwXMLAttribute defines an attribute. Attributes with empty name or value will be ignored
	TThreadMapRec	This is record TThreadMapRec.

Types

Name	Description
TJwEventTypes	This is type TJwEventTypes.
TJwOnXMLWrite	TJwOnXMLWrite is called after the xml lines has been generated. Its value is stored into parameter Result. Set parameter result to empty if you don't want the xml line to be stored into the internal string list.
TJwOnXMLWriting	TJwOnXMLWriting is called before code is processed in IJwWriterClass The function receives information about the xml line to be generated.
TJwXMLAttributes	TJwXMLAttributes defines an dynamic array of attributes
TThreadMapRecs	This is type TThreadMapRecs.

Variables

Name	Description
JwEnterTypeString	strings for enter/leave tag type value
JwLogTypeStrings	strings for log tag value
JwMemoryTypeString	strings for memory type value
JwSignalTypeString	strings for signal tag type value
JwStrIdent	JwStrNewLine : AnsiString = #13#10; identation string (default #9 = tabulator char)
JwTimeOutputString	format of start attribute value for processlog tag
JwXMLAttributeString	strings type attribute names
