Method Detail

• setDefaultImports

  public void setDefaultImports​(java.lang.String[] optionalDefaultImports)

  Description copied from interface: IClassBodyEvaluator
  "Default imports" add to the system import "java.lang", i.e. the evaluator may refer to classes imported by default imports without having to explicitly declare IMPORT statements.

  Notice that JDK 5 "static imports" are also supported, as shown in the following example.

  Example:

       sc.setDefaultImports(new String[] {
           "java.util.Map",                          // Single type import
           "java.io.*",                              // Type-import-on-demand
           "static java.util.Collections.EMPTY_MAP", // Single static import
           "static java.util.Collections.*",         // Static-import-on-demand
       });

  Specified by:

  setDefaultImports in interface IClassBodyEvaluator

• setClassName

  public void setClassName​(java.lang.String className)

  Description copied from interface: IClassBodyEvaluator
  Set the name of the generated class. Defaults to IClassBodyEvaluator.DEFAULT_CLASS_NAME. In most cases, there is no need to set this name, because the generated class is loaded into its own ClassLoader where its name cannot collide with classes generated by other evaluators.

  One reason to use this function is to have a class name in a non-default package, which can be relevant when types and members with DEFAULT accessibility are accessed.

  Specified by:

  setClassName in interface IClassBodyEvaluator

• setExtendedClass

  public void setExtendedClass​(java.lang.Class optionalExtendedType)

  Description copied from interface: IClassBodyEvaluator
  Set a particular superclass that the generated class will extend. If null is passed, the generated class will extend Object.

  The common reason to set a base class for an evaluator is that the generated class can directly access the base superclass's (non-private) members.

  Specified by:

  setExtendedClass in interface IClassBodyEvaluator

• setExtendedType

  @Deprecated
  public void setExtendedType​(java.lang.Class optionalExtendedClass)

  Deprecated.

  Specified by:

• setImplementedInterfaces

  public void setImplementedInterfaces​(java.lang.Class[] implementedTypes)

  Description copied from interface: IClassBodyEvaluator
  Set a particular set of interfaces that the generated class will implement.

  Specified by:

  setImplementedInterfaces in interface IClassBodyEvaluator

• setImplementedTypes

  @Deprecated
  public void setImplementedTypes​(java.lang.Class[] implementedInterfaces)

  Deprecated.

  Specified by:

• cook

  public void cook​(Scanner scanner)
            throws CompileException,
                   java.io.IOException

  Description copied from class: SimpleCompiler
  Scans, parses and ompiles a given compilation unit from the given scanner. After completion, SimpleCompiler.getClassLoader() returns a ClassLoader that allows for access to the compiled classes.

  Overrides:

  cook in class SimpleCompiler

  Throws:

  CompileException

  java.io.IOException

• makeCompilationUnit

  protected final Java.CompilationUnit makeCompilationUnit​(Parser optionalParser)

                                                           java.io.IOException

  Create a Java.CompilationUnit, set the default imports, and parse the import declarations.

  If the optionalParser is given, a sequence of IMPORT directives is parsed from it and added to the compilation unit.

  Throws:

  CompileException

  java.io.IOException

• addPackageMemberClassDeclaration
