class XxxEnvironment

Defines the environment for each client

Inheritance:

Public Classes

class

GeneralStats / class RecordStats / record-level activity for this client class ShoreStats / SHORE activity for this client class ExprStats / expr-level activity for this client

Public Fields

static XxxDBEngine*	DBEngineArray [] / This is PREDATOR's engine array; each engine inserts itself
XxxJavaVirtualMachine*	JVM This is the JavaVM wrapper object for this env (i.e. its thread)
static smutex_t*	Latch Latch is used to synchronize access to the engine array
static int	NumDBEngines / The number of engines defined in the system

Public Methods

XxxErrCode	DumpStorage () Removes the temp file
XxxErrCode	InitStorage () Initializes storage information for the environment
XxxErrCode	ShutJVM () / Close the JVM
XxxErrCode	StartJVM () / Initialize the JVM

static smutex_t* Latch

Latch is used to synchronize access to the engine array

static XxxDBEngine* DBEngineArray[]

/ This is PREDATOR's engine array; each engine inserts itself

static int NumDBEngines

/ The number of engines defined in the system

class GeneralStats

/

class RecordStats

/ record-level activity for this client

class ShoreStats

/ SHORE activity for this client

class ExprStats

/ expr-level activity for this client

XxxJavaVirtualMachine* JVM

This is the JavaVM wrapper object for this env (i.e. its thread)

XxxErrCode InitStorage()

Initializes storage information for the environment. This requires that SHORE is up and running and should be run for every client's environment, since it generates a temporary file. However, it should not be run on callbacks' environments, since the temp file must be shared.

XxxErrCode DumpStorage()

Removes the temp file

XxxErrCode StartJVM()

/ Initialize the JVM

XxxErrCode ShutJVM()

/ Close the JVM
