These classes need to implement executeScript, evaluateScript and supportsLanguage. since:    Ant 1.7.0 Method Summary public  void addBean(String key, Object bean)      Add a single object into the script context. public  void addBeans(Map dictionary)      public  void addText(String text)      Set the script text. public  void bindToComponent(ProjectComponent component)      Bind the runner to a project component. public  void bindToComponentMinimum(ProjectComponent component)      Bind the runner to a project component. protected  void checkLanguage()      Check if the language attribute is set. public  void clearScript()      Clear the current script text content. abstract public  Object evaluateScript(String execName)      Evalulate the script. Parameters:   execName - the name that will be passed to BSF for this scriptexecution. abstract public  void executeScript(String execName)      Do the work. protected  Map getBeans()      Get the beans used for the script. public  boolean getKeepEngine()      Get the keep engine attribute. public  String getLanguage()      abstract public  String getManagerName()      Get the name of the manager prefix used for this scriptrunner. public  Project getProject()      Get the project for this runner. public  String getScript()      Get the current script text content. protected  ClassLoader getScriptClassLoader()      Get the classloader used to load the script engine. protected  ClassLoader replaceContextLoader()      Replace the current context classloader with the script context classloader. protected  void restoreContextLoader(ClassLoader origLoader)      Restore the context loader with the original context classloader. public  void setKeepEngine(boolean keepEngine)      Whether to keep the script engine between calls. public  void setLanguage(String language)      Defines the language (required). public  void setProject(Project project)      Set the project for this runner. public  void setScriptClassLoader(ClassLoader classLoader)      Set the script classloader. public  void setSrc(File file)      Load the script from an external file; optional. abstract public  boolean supportsLanguage()      Check if a script engine can be created for this language. Method Detail addBean public void addBean(String key, Object bean)(Code) Add a single object into the script context. Parameters:   key - the name in the context this object is to stored under. Parameters:   bean - the object to be stored in the script context. addBeans public void addBeans(Map dictionary)(Code) Add a list of named objects to the list to be exported to the script Parameters:   dictionary - a map of objects to be placed into the script contextindexed by String names. addText public void addText(String text)(Code) Set the script text. Parameters:   text - a component of the script text to be added. bindToComponent public void bindToComponent(ProjectComponent component)(Code) Bind the runner to a project component. Properties, targets and references are all added as beans; project is bound to project, and self to the component. Parameters:   component - to become self bindToComponentMinimum public void bindToComponentMinimum(ProjectComponent component)(Code) Bind the runner to a project component. The project and self are the only beans set. Parameters:   component - to become self checkLanguage protected void checkLanguage()(Code) Check if the language attribute is set. throws:   BuildException - if it is not. clearScript public void clearScript()(Code) Clear the current script text content. evaluateScript abstract public Object evaluateScript(String execName)(Code) Evalulate the script. Parameters:   execName - the name that will be passed to BSF for this scriptexecution. the result of evalulating the script. executeScript abstract public void executeScript(String execName)(Code) Do the work. Parameters:   execName - the name that will be passed to BSF for this scriptexecution. getBeans protected Map getBeans()(Code) Get the beans used for the script. the map of beans. getKeepEngine public boolean getKeepEngine()(Code) Get the keep engine attribute. the attribute. getLanguage public String getLanguage()(Code) Get the script language the script language getManagerName abstract public String getManagerName()(Code) Get the name of the manager prefix used for this scriptrunner. the prefix string. getProject public Project getProject()(Code) Get the project for this runner. the project. getScript public String getScript()(Code) Get the current script text content. the script text. getScriptClassLoader protected ClassLoader getScriptClassLoader()(Code) Get the classloader used to load the script engine. the classloader. replaceContextLoader protected ClassLoader replaceContextLoader()(Code) Replace the current context classloader with the script context classloader. the current context classloader. restoreContextLoader protected void restoreContextLoader(ClassLoader origLoader)(Code) Restore the context loader with the original context classloader. script context loader. Parameters:   origLoader - the original context classloader. setKeepEngine public void setKeepEngine(boolean keepEngine)(Code) Whether to keep the script engine between calls. Parameters:   keepEngine - if true, keep the engine. setLanguage public void setLanguage(String language)(Code) Defines the language (required). Parameters:   language - the scripting language name for the script. setProject public void setProject(Project project)(Code) Set the project for this runner. Parameters:   project - the project. setScriptClassLoader public void setScriptClassLoader(ClassLoader classLoader)(Code) Set the script classloader. Parameters:   classLoader - the classloader to use. setSrc public void setSrc(File file)(Code) Load the script from an external file; optional. Parameters:   file - the file containing the script source. supportsLanguage abstract public boolean supportsLanguage()(Code) Check if a script engine can be created for this language. true if a script engine can be created, falseotherwise.
