| CompiledTables | | public class CompiledTables (Code) | | 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");

LALRParserTables.class wil be the type of created parser tables.
Parameters:
syntaxInput - the Parser syntax as File, InputStream, List of Lists, String [][] or Syntax.
Parameters:
className - name of target class of ParserTables, without package path, without .java extension. | | public AbstractParserTables | get(Class parserType, Object syntaxInput, String className)
