## Uses of Package
org.opensolaris.os.dtrace

Classes in org.opensolaris.os.dtrace used by org.opensolaris.os.dtrace
Aggregate A consistent snapshot of all aggregations requested by a single `Consumer`.
Aggregation A snapshot of a DTrace aggregation.
AggregationRecord A single key-value pair in a DTrace aggregation.
AggregationValue A value accumulated by an aggregating DTrace action such as `count()` or `sum()`.
Consumer Interface to the native DTrace library, each instance is a single DTrace consumer.
Consumer.OpenFlag Optional flags passed to `open()`.
ConsumerEvent An event indicating a state change in a DTrace `Consumer`.
ConsumerException Exception thrown by a `ConsumerListener` to terminate a running `Consumer`.
ConsumerListener Listener for data generated by a single DTrace `Consumer`.
DataEvent An event used to pass probe data generated by a DTrace `Consumer` to interested listeners.
Distribution A frequency distribution aggregated by the DTrace `quantize()` or `lquantize()` action.
Distribution.Bucket A range inclusive at both endpoints and a count of aggregated values that fall in that range.
Drop Detail about one or more records dropped by DTrace (not reported to `ConsumerListener.dataReceived()`) due to inadequte buffer space.
Drop.Kind Indicates what kind of buffer space experienced the data drop (such as principal buffer or aggregation buffer) and possibly a reason.
DropEvent Notification that DTrace has dropped data due to inadequate buffer space.
DTraceException Exception in the native DTrace library.
Error An error encountered in the native DTrace library while tracing probe data.
ErrorEvent Notification that DTrace has encountered an error.
ExceptionHandler User-defined application behavior after an exception terminates a running DTrace consumer.
Flow Description of control flow across function boundaries including direction (entry or return) and depth in the call stack.
Flow.Kind Indicates direction of flow across a boundary, such as entering or returing from a function.
InterfaceAttributes Triplet of attributes consisting of two stability levels and a dependency class.
InterfaceAttributes.DependencyClass Architectural dependency class.
InterfaceAttributes.Stability Interface stability level.
KernelStackRecord A value generated by the DTrace `stack()` action.
KernelSymbolRecord A value generated by the DTrace `mod()`, `func()`, or `sym()` action used to lookup the symbol associated with a kernel address.
LinearDistribution A linear frequency distribution aggregated by the DTrace `lquantize()` action.
LogDistribution A power-of-two logarithmic frequency distribution aggregated by the DTrace `quantize()` action.
Probe A `ProbeDescription` identifying a single probe combined with information about the identified probe.
ProbeData Data generated when a DTrace probe fires, contains one record for every record-generating action in the probe.
ProbeData.KeyField Enumerates the fields by which `ProbeData` may be sorted using the `getComparator()` convenience method.
ProbeDescription A DTrace probe description consists of provider, module, function, and name.
ProbeDescription.Spec Enumerates the provider, module, function, and name fields of a probe description.
ProbeInfo Probe stability information.
ProcessEvent Notification that the state of a target process designated by `Consumer.createProcess(String command)` or `Consumer.grabProcess(int pid)` has changed.
ProcessState State of a target process designated by `Consumer.createProcess(String command)` or `Consumer.grabProcess(int pid)`.
ProcessState.State State of a target process.
Program Identifies a compiled D program.
ProgramInfo Information about a `Program` including stability and matching probe count.
Record A data record generated by DTrace.
StackFrame A single stack frame in a `StackValueRecord`.
StackValueRecord A value generated by the DTrace `stack()`, `ustack()`, or `jstack()` action.
SymbolValueRecord A value generated by the DTrace `mod()`, `func()`, `sym()`, `umod()`, `ufunc()` or `usym()` action used to lookup the symbol associated with an address in probe context.
Tuple Multi-element key to a value in an `Aggregation`.
UserStackRecord A value generated by the DTrace `ustack()` or `jstack()` action.
UserSymbolRecord A value generated by the DTrace `umod()`, `ufunc()`, or `usym()` action used to lookup the symbol associated with a user address.
UserSymbolRecord.Value The composite value of a symbol's process ID and user address.
ValueRecord A data record generated by DTrace that contains a single value.
