      net.sf.saxon.trace.TimingCodeInjector

All Implemented Interfaces:

CodeInjector

public class TimingCodeInjector
extends TraceCodeInjector

A code injector that wraps the body of a template or function in a TraceExpression, which causes the TimingTraceListener to be notified at the start and end of the function/template evaluation

If tracing, wrap an expression in a trace instruction

Specified by:

inject in interface CodeInjector

Overrides:

inject in class TraceCodeInjector

Parameters:

exp - the expression to be wrapped

env - the static context

construct - integer constant identifying the kind of construct

qName - the name of the construct (if applicable)

Returns:

the expression that does the tracing
