Interface ISimpleCompiler
- All Superinterfaces:
ICookable
- All Known Implementing Classes:
SimpleCompiler
,SimpleCompiler
Opposed to a normal ".java" file, you can declare multiple public classes here.
To set up an ISimpleCompiler
object, proceed as follows:
- Create an
ISimpleCompiler
-implementing object - Optionally set an alternate parent class loader through
setParentClassLoader(ClassLoader)
. -
Call any of the
ICookable.cook(String, Reader)
methods to scan, parse, compile and load the compilation unit into the JVM. -
Call
getClassLoader()
to obtain aClassLoader
that you can use to access the compiled classes.
Comptibility notice:
The methods setPermissions(Permissions permissions)
and void setNoPermissions()
were removed in
version 3.1.1 (2020-03-09) and replaced by the Sandbox
.

Method Summary
Modifier and TypeMethodDescriptionReturns aClassLoader
object through which the previously compiled classes can be accessed.void
setCompileErrorHandler
(ErrorHandler compileErrorHandler) Installs anErrorHandler
which is invoked during compilation on each error.void
setDebuggingInformation
(boolean debugSource, boolean debugLines, boolean debugVars) Determines what kind of debugging information is included in the generates classes.void
setParentClassLoader
(ClassLoader parentClassLoader) The "parent class loader" is used to load referenced classes.void
setWarningHandler
(WarningHandler warningHandler) By default, warnings are discarded, but an application my install a customWarningHandler
which is invoked for each warning.

Method Details
-
setParentClassLoader
The "parent class loader" is used to load referenced classes. Useful values are:System.getSystemClassLoader()
The running JVM's class path Thread.currentThread().getContextClassLoader()
ornull
The class loader effective for the invoking thread ClassLoaders.BOOTCLASSPATH_CLASS_LOADER
The running JVM's boot class path The parent class loader defaults to the current thread's context class loader.
-
setDebuggingInformation
void setDebuggingInformation(boolean debugSource, boolean debugLines, boolean debugVars) Determines what kind of debugging information is included in the generates classes. The default is typically "-g:none
". -
setCompileErrorHandler
Installs anErrorHandler
which is invoked during compilation on each error. (By default, the compilation throws aCompileException
on the first error and terminates.)If the given
ErrorHandler
throws aCompileException
, then the compilation terminates and the exception is propagated.If the given
ErrorHandler
does not throw aCompileException
but completes normally, then the compilation may or may not continue, depending on the error. Iff the compilation completes normally but errors were reported, then it will throw aCompileException
indicating the number of errors.In other words: The
ErrorHandler
may throw aCompileException
or not, but the compilation will definitely throw aCompileException
if one or more compile errors have occurred.- Parameters:
compileErrorHandler
-null
to restore the default behavior (throwing aCompileException
)
-
setWarningHandler
By default, warnings are discarded, but an application my install a customWarningHandler
which is invoked for each warning. If, for some untypical reason, that warning handler wants to terminate the compilation as quickly as possible, then it would throw aCompileException
.- Parameters:
warningHandler
-null
to indicate that no warnings be issued
-
getClassLoader
ClassLoader getClassLoader()Returns aClassLoader
object through which the previously compiled classes can be accessed. ThisClassLoader
can be used for subsequentISimpleCompiler
s in order to compile compilation units that use types (e.g. declare derived types) declared in the previous one.This method must only be called after exactly one of the
ICookable.cook(String, java.io.Reader)
methods was called.
