annotate graal/com.oracle.truffle.api/src/com/oracle/truffle/api/instrument/Instrument.java @ 20106:2e3cc2a27711
Truffle/Instrumentation: a new flavor of Instrument that lazily provides an AST fragment to be attached/adopted directly into a running AST, and to which execution event notifications will be routed. Important use cases so far include conditional breakpoints (with optimizeable conditions) and Ruby set_trace_func.

Truffle/Instrumentation: a new flavor of Instrument that lazily provides an AST fragment to be attached/adopted directly into a running AST, and to which execution event notifications will be routed. Important use cases so far include conditional breakpoints (with optimizeable conditions) and Ruby set_trace_func.

Truffle/Instrumentation: For clients of Instrumentation, replace the TruffleEventListener interface with two: InstrumentListener, and ASTInstrumentListener. The former is simple, completely Truffle-safe (can't affect Truffle execution), and designed for simple tools. The latter is similar to the previous interface.

Truffle/Instrumentation: For clients of Instrumentation, replace the TruffleEventListener interface with two: InstrumentListener, and ASTInstrumentListener. The former is simple, completely Truffle-safe (can't affect Truffle execution), and designed for simple tools. The latter is similar to the previous interface.
