Class UnitCompiler
java.lang.Object
org.codehaus.janino.UnitCompiler
This class actually implements the Java™ compiler. It is associated with exactly one compilation unit which it
compiles.

findIMethod
Find named methods of "targetType", examine the argument types and choose the most specific method. Check that only the allowed exceptions are thrown.Notice that the returned
IClass.IMethodmay be declared in an enclosing type.- Returns:
- The selected
IClass.IMethodornull - Throws:
CompileException

public IClass.IInvocable findMostSpecificIInvocable(Java.Locatable locatable, IClass.IInvocable[] iInvocables, IClass[] argumentTypes, boolean boxingPermitted, Java.Scope contextScope) throws CompileException Determine the applicable invocables and choose the most specific invocable.- Returns:
- The maximally specific
IClass.IInvocableornullif noIClass.IInvocableis applicable - Throws:

getSingleTypeImport
Check if the given simple name was imported through a single type import.- Parameters:
name- The simple type name, e.g.Inner- Returns:
- The fully qualified name, e.g.
{ "pkg", "Outer", "Inner" }, ornull - Throws:
CompileException
-

6.5.5.1.6 Type-import-on-demand declaration.- Returns:
nullif the givensimpleTypeNamecannot be resolved through any of the import-on-demand directives- Throws:
CompileException
-
findClass
Find one class or interface declared in this compilation unit by name.- Parameters:
className- Fully qualified class name, e.g. "pkg1.pkg2.Outer$Inner".- Returns:
nullif a class or an interface with that name is not declared in this compilation unit
-
setCompileErrorHandler
By default,CompileExceptions are thrown on compile errors, but an application my install its own (thread-local)UnitCompiler.ErrorHandler.Be aware that a single problem during compilation often causes a bunch of compile errors, so a good
UnitCompiler.ErrorHandlercounts errors and throws aCompileExceptionwhen a limit is reached.If the given
UnitCompiler.ErrorHandlerdoes not throwCompileExceptions, thencompileUnit(boolean, boolean, boolean)will throw one when the compilation of the unit is finished, and errors had occurred. In other words: TheUnitCompiler.ErrorHandlermay throw aCompileExceptionor not, butcompileUnit(boolean, boolean, boolean)will definitely throw aCompileExceptionif one or more compile errors have occurred.- Parameters:
optionalCompileErrorHandler-nullto restore the default behavior (throwing aCompileException
-
setWarningHandler
By default, warnings are discarded, but an application my install a customWarningHandler.- Parameters:
optionalWarningHandler-nullto indicate that no warnings be issued
