getStaticExpressionRuntime
public static StaticExpressionRuntimeData getStaticExpressionRuntime(FlowController fc, java.lang.Object declaringParent)
-
getExpressionRuntime
public static LayoutExpressionRuntime getExpressionRuntime(FlowController fc, java.lang.Object node)
-
processFlowOperations
public static FlowController processFlowOperations(FlowController fc, FlowControlOperation[] ops) throws DataSourceException
- Throws:
DataSourceException
-
isGroupFinished
public static boolean isGroupFinished(FlowController fc, Node node) throws DataSourceException
Checks, whether the current group should continue. If there is no group, we assume that we should continue. (This emulates the control-break-algorithm's default behaviour if testing an empty set of arguments.)- Parameters:
fc
- the current flow controller holding the datanode
- the current node.- Returns:
- true, if the group is finished and we should stop reiterating it, false if the group is not finished and we can start iterating it again.
- Throws:
DataSourceException
-
