TraceSystem

The trace mechanism is the logging facility of this database. There is usually one trace system per database. It is called 'trace' because the term 'log' is already used in the database domain and means 'transaction log'. It is possible to write after close was called, but that means for each write the file will be opened and closed again (which is slower).

Methods
	TraceSystem(String fileName) Create a new trace system object.
	TraceSystem(String fileName) Create a new trace system object. Parameters: fileName - the file name
void	close() Close the writers, and the files if required.
void	close() Close the writers, and the files if required. It is still possible to write after closing, however after each write the file is closed again (slowing down tracing).
int	getLevelFile()
int	getLevelFile()
Trace	getTrace(int moduleId) Get or create a trace object for this module id.
Trace	getTrace(int moduleId) Get or create a trace object for this module id. Trace modules with id are cached. Parameters: moduleId - module id Returns: the trace object
Trace	getTrace(String module) Create a trace object for this module.
Trace	getTrace(String module) Create a trace object for this module. Trace modules with names are not cached. Parameters: module - the module name Returns: the trace object
boolean	isEnabled(int level)
boolean	isEnabled(int level)
void	setFileName(String name) Set the trace file name.
void	setFileName(String name) Set the trace file name. Parameters: name - the file name
void	setLevelFile(int level) Set the file trace level.
void	setLevelFile(int level) Set the file trace level. Parameters: level - the new level
void	setLevelSystemOut(int level) Set the trace level to use for System.out
void	setLevelSystemOut(int level) Set the trace level to use for System.out Parameters: level - the new level
void	setMaxFileSize(int max) Set the maximum trace file size in bytes.
void	setMaxFileSize(int max) Set the maximum trace file size in bytes. Parameters: max - the maximum size
void	setName(String name)
void	setName(String name)
void	setSysOut(PrintStream out) Set the print stream to use instead of System.out.
void	setSysOut(PrintStream out) Set the print stream to use instead of System.out. Parameters: out - the new print stream
void	write(int level, int moduleId, String s, Throwable t)
void	write(int level, int moduleId, String s, Throwable t)
void	write(int level, String module, String s, Throwable t)
void	write(int level, String module, String s, Throwable t)
