getInitializationContext

public FlowContext getInitializationContext()

Description copied from class: FlowContext

Answer flow context that corresponds to initialization. Suitably override in subtypes.

Overrides:

getInitializationContext in class FlowContext

individualToString

public String individualToString()

Overrides:

individualToString in class FlowContext

initsOnException

public UnconditionalFlowInfo initsOnException(int index)

initsOnReturn

public UnconditionalFlowInfo initsOnReturn()

Overrides:

initsOnReturn in class FlowContext

mergeUnhandledException

public void mergeUnhandledException(TypeBinding newException)

recordHandlingException

public void recordHandlingException(ReferenceBinding exceptionType,
 UnconditionalFlowInfo flowInfo,
 TypeBinding raisedException,
 TypeBinding caughtException,

recordReturnFrom

public void recordReturnFrom(UnconditionalFlowInfo flowInfo)

Overrides:

recordReturnFrom in class FlowContext

subroutine

public SubRoutineStatement subroutine()

Exception handlers (with no finally block) are also included with subroutine only once (in case parented with true InsideSubRoutineFlowContext). Standard management of subroutines need to also operate on intermediate exception handlers.

Overrides:

subroutine in class FlowContext
