      org.obe.xpdl.model.ext.ToolMode

All Implemented Interfaces:

java.lang.Comparable, Enum, java.io.Serializable

public final class ToolMode

extends AbstractEnum

The ToolMode is used to indicate whether the tools in a tool set should be executed sequentially or in parallel. The default is SEQUENTIAL. This attribute is not described in the XPDL specification, but its predecessor WPDL states that the workflow engine creates one work item per tool, and that execution flow between these work items (and thus the invocation order of the tools) can be controlled in a vendor-specific manner. The WPDL spec. does suggest SEQUENTIAL or PARALLEL modes, and states that the default is SEQUENTIAL (curious that the spec. defines the default for a vendor-specific attribute?).
