    • replaceFunctionCall

      public boolean replaceFunctionCall(JavaRewriter.ComponentInfo componentInfo, String function, Object value)
      Replaces a constructor parameter (if it is mapped to the given setter function) or a function call in the source code.
      Parameters:
      componentInfo - the component to modify
      function - the name of the function to replace or add, if the constructor parameter is not found
      value - the new value for the constructor parameter or function call
      Returns:
      true if the replacement was successful, false otherwise

    • addCall

      public boolean addCall(JavaRewriter.ComponentInfo componentInfo, String function, Object parameter)
      Adds a function call to the source code.
      Parameters:

      function - the name of the function to add
      parameter - the parameter for the function
      Returns:
      true if the addition was successful, false otherwise

    • replaceOrAddCall

      public boolean replaceOrAddCall(JavaRewriter.ComponentInfo componentInfo, String function, Object parameter)
      Replaces a function call in the source code, if found, otherwise adds the function call.

    • getPropertyValue

      public Object getPropertyValue(JavaRewriter.ComponentInfo componentInfo, String property)
      Gets the (active) value of a property of a component.

      The property value is determined by looking for a setter method call in the source code. If the property is not set using a setter, the constructor is checked.

      If the property is not set using a setter or in the constructor, null is returned.

      If the property is set using a method call, the method call expression is returned.

      Parameters:
      componentInfo - the component to get the property value from
      property - the property name
      Returns:
      the property value, or null if the property is not set
