org.aspectj.org.eclipse.jdt.core.compiler.IScanner
Definition of a Java scanner, as returned by the ToolFactory. The scanner is responsible for tokenizing a given source, providing information about the nature of the token read, its positions and source equivalent.
When the scanner has finished tokenizing, it answers an EOF token ( ITerminalSymbols#TokenNameEOF.
When encountering lexical errors, an InvalidInputException is thrown.
This interface is not intended to be implemented by clients.
