outerTryContext

public FlowContext outerTryContext

For a try statement nested inside a finally block this reference points to the flow context of the outer try block, for access to its initsOnFinally.

Constructor Details

TryFlowContext

public TryFlowContext(FlowContext parent,
 ASTNode associatedNode)

Method Details

markFinallyNullStatus

public void markFinallyNullStatus(LocalVariableBinding local,
 int nullStatus)

Description copied from class: FlowContext

Record a given null status of a given local variable as it will be seen in the finally block.

Overrides:

markFinallyNullStatus in class FlowContext

Parameters:

local - the local variable being observed

nullStatus - the null status of local at the current point in the flow

mergeFinallyNullInfo

public void mergeFinallyNullInfo(FlowInfo flowInfo)

Description copied from class: FlowContext

Merge the effect of a statement presumably contained in a try-block, i.e., record how the collected info will affect the corresponding finally-block. Precondition: caller has checked that initsOnFinally != null.

Overrides:

mergeFinallyNullInfo in class FlowContext

Parameters:

flowInfo - info after executing a statement of the try-block.
