+## Functions

+The public methods of this class are:
+
+| Name | Params | Description | Returns |
+|-|-|-|-|
+| **add_error** | **error -> Dictionary:** <br> Custom error. | Raises a custom error, if you want it to have the 'as_text' property, include your custom error message in an 'error' property. | Nothing. |
+| **add_warning** | **warning -> Dictionary:** <br> Custom warning. | Raises a custom warning, if you want it to have the 'as_text' property, include your custom warning message in an 'warning' property. | Nothing. |
+| **set_variable** | **name -> String:** <br> Name of the global variable to set. <br> **value -> Variant:** <br> The value assigned to this global variable. | Creates a global variable or modify the value of a previously existing one. | Nothing. |
+| **has_variable** | **name -> String:** <br> Name of the global variable to check. | Checks if the global variable exists. | **bool:** <br> If the global variable exists. |
+| **get_variable** | **name -> String:** <br> Name of the global variable to get. | Gets the value of the specified global variable. | **Variant:** <br> The value of the global variable. If the variable is undefined, it will return null. |
+| **get_property** | None. | Returns the JSON property in which this processor is located. | **JSONProperty:** <br> The JSON property in which this processor is located.
