Class NaiveASTFlattener

java.lang.Object
  org.eclipse.jdt.core.dom.ASTVisitor
      org.eclipse.jdt.core.dom.NaiveASTFlattener

class NaiveASTFlattener
extends ASTVisitor

Internal AST visitor for serializing an AST in a quick and dirty fashion. For various reasons the resulting string is not necessarily legal Java code; and even if it is legal Java code, it is not necessarily the string that corresponds to the given AST. Although useless for most purposes, it's fine for generating debug print strings.

Example usage:

    NaiveASTFlattener p = new NaiveASTFlattener();
    node.accept(p);
    String result = p.getResult();

Call the reset method to clear the previous result before reusing an existing instance.

Since:: 2.0

Field Summary

private java.lang.StringBuffer buffer
          The string buffer into which the serialized representation of the AST is written.
