The root of the Abstract Syntax Tree for the source
A Concrete Syntax Tree of the source
A descriptive name of the source unit. This name shouldn't be used for controlling the SourceUnit, it is only for error messages and to determine the name of the class for a script.
Where we can get Readers for our source unit
Initializes the SourceUnit from existing machinery.
Initializes the SourceUnit from the specified file.
Initializes the SourceUnit from the specified URL.
Initializes the SourceUnit for a string of source.
This method adds a SyntaxException to the error collector. The exception should specify the line and column number of the error. This method should be reserved for real errors in the syntax of the SourceUnit. If your error is not in syntax, and is a semantic error, or more general error, then use addException or use the error collector directly by retrieving it with getErrorCollector().
se
- the exception, which should have line and column informationThis method adds an exception to the error collector. The Exception most likely has no line number attached to it. For this reason you should use this method sparingly. Prefer using addError for syntax errors or add an error to the ErrorCollector directly by retrieving it with getErrorCollector().
e
- the exception that occurredGenerates an AST from the CST. You can retrieve it with getAST().
