Probe definitions

The top-level Probe entry in the Probekit editor tree pane represents the definition of a single probe. Probes are contained in a Probekit source file with the extension .probe. A Probekit source file can contain more than one probe.

• Probe import directives
  Import directives are statements that specify the Java packages and classes that are referenced by the probe.
• Probe target specifications
  A target specification indicates the classes and methods to which the probe should be applied.
• Probe fragments
  A probe's fragment defines the probe's logic. Every probe must contain at least one fragment.
• Probe fragments at class scope
  The fragment at class scope specifies the data and initialization requirements of a probe, if any.
• Probe static fields
  A probe's static field inserts a new static field into every Java class that contains at least one method that is instrumented by the probe. This static field is accessible to probe fragments, and can be used to store information inside probed classes.
