    • addToolbox

      public void addToolbox(Toolbox toolbox)

    • getToolbox

      public Map<String,Object> getToolbox()
      Returns a Map of all tools available to this context. NOTE: this is not a cheap operation as it will request and initialize an instance of every available tool.
      返回:
      aggregated toolbox of all available tools

    • getToolClassMap

      public Map<String,Class> getToolClassMap()
      Gets a map of keys to classes for all available tools. This does not include any data nor any local context values.
      返回:
      aggregated map of all available tools classes

    • getToolboxes

      protected List<Toolbox> getToolboxes()

    • getToolProperties

      protected Map<String,Object> getToolProperties()

    • putVelocityEngine

      public void putVelocityEngine(org.apache.velocity.app.VelocityEngine engine)
      Puts the specified VelocityEngine in the tool properties, as well as the Log for that engine. Last, if the specified engine has a MethodExceptionEventHandler configured, then this will automatically set CATCH_EXCEPTIONS_KEY to false in the tool properties.
      参数:
      engine - VelocityEngine instance
