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.
