Method Detail

setTraceFilter

public void setTraceFilter(ITraceFilter filter)

Description copied from interface: ITracer

Sets a trace filter on this tracer.

Specified by:

setTraceFilter in interface ITracer

Parameters:

filter - the new trace filter, ignored if null

getTraceFilter

public ITraceFilter getTraceFilter()

Description copied from interface: ITracer

Returns the active trace filter.

Specified by:

getTraceFilter in interface ITracer

Returns:

the filter, may be null if the tracer does not support filters

trace

public void trace(java.lang.String text)

Description copied from interface: ITracer

Emits a trace string.

Specified by:

trace in interface ITracer

Parameters:

text - the text to be emitted

valueDefined

public void valueDefined(VariableDeclaration var,
                         FieldDescriptor field,
                         java.lang.Object value)

Description copied from interface: ITracer

Is called when a value of a variable is defined.

Specified by:

valueDefined in interface ITracer

Parameters:

var - the modified variable

field - the field in var, may be null

value - the actual value

traceExecutionException

public void traceExecutionException(VilException exception)
