Class VelocimacroManager


  • public class VelocimacroManager
    extends java.lang.Object
    Manages VMs in namespaces. Currently, two namespace modes are supported:
    • flat - all allowable VMs are in the global namespace
    • local - inline VMs are added to it's own template namespace
    Thanks to Jose Alberto Fernandez for some ideas incorporated here.

        vmName - Name of the new VelociMacro.
        macroBody - String representation of the macro body.
        argArray - Array of macro parameters, first parameter is the macro name.
        namespace - The namespace/template from which this macro has been loaded.
        Returns:
        Whether everything went okay.
      • get

      • dumpNamespace

        public boolean dumpNamespace​(java.lang.String namespace)
        Removes the VMs and the namespace from the manager. Used when a template is reloaded to avoid losing memory.
        Parameters:
        namespace - namespace to dump
        Returns:
        boolean representing success
      • setNamespaceUsage

        public void setNamespaceUsage​(boolean namespaceOn)
        public switch to let external user of manager to control namespace usage indep of properties. That way, for example, at startup the library files are loaded into global namespace
        Parameters:
        namespaceOn - True if namespaces should be used.
      • setRegisterFromLib

        public void setRegisterFromLib​(boolean registerFromLib)
        Should macros registered from Libraries be marked special?
        Parameters:
        registerFromLib - True if macros from Libs should be marked.
      • setTemplateLocalInlineVM

        public void setTemplateLocalInlineVM​(boolean inlineLocalMode)
        Should macros from the same template be inlined?
        Parameters:
        inlineLocalMode - True if macros should be inlined on the same template.
      • getLibraryName

        public java.lang.String getLibraryName​(java.lang.String vmName,
                                               java.lang.String namespace)
        Return the library name for a given macro.
        Parameters:
        vmName - Name of the Macro to look up.
        namespace - Namespace to look the macro up.
        Returns:
        The name of the library which registered this macro in a namespace.
