Deprecated. in favor of serialization

public class CompiledTables

extends java.lang.Object

This class is deprecated in favor of serialization.

CompiledTables buffers parser tables by generating source and compiling that source. This lasts very long at first time, but is faster than serialization for every subsequent call. The class will be posted in current directory (has no package). The source gets removed after successful compilation. The Sun compiler must be in package path, which is normally in $JAVA_HOME/lib/tools.jar.

Building compiled Java ParserTables takes 1600, building from scratch takes 6000 millis. CompiledTables seem to be slower than SerializedParser!

An alternative to compiled tables is generating the parser tables source with SourceGenerator and integrating that source into project sources. This avoids the dynamically created class in working directory and the neccessity to have javac in CLASSPATH at runtime.

                ParserTables tables = new CompiledTables().get(syntaxInput, "MyParserTables");

Parameters:

syntaxInput - the Parser syntax as File, InputStream, List of Lists, String [][] or Syntax.

Returns:

ParserTables object, or object built from scratch that gets compiled into current directory.

java.lang.Exception

Parameters:

syntaxInput - the Parser syntax as File, InputStream, List of Lists, String [][] or Syntax.

className - name of target class of ParserTables, without package path, without .java extension.

parserType - class of ParserTables to create, e.g. LALRParserTables.class
