-/**
- * A node for the string conversion operation. See JLS 5.1.11 for the definition of string
- * conversion.
- *
- * <p>A {@link StringConversionNode} does not correspond to any tree node in the parsed AST. It is
- * introduced when a value of non-string type appears in a context that requires a {@link String},
- * such as in a string concatenation. A {@link StringConversionNode} should be treated as a
- * potential call to the toString method of its operand, but does not necessarily call any method
- * because null is converted to the string "null".
- *
- * <p>Conversion of primitive types to Strings requires first boxing and then string conversion.
