package ba

Implementation of an eDSL for creating Java bytecode. The eDSL is designed to facilitate the creation of correct class files; i.e., whenever possible it tries to fill wholes. For example, when an interface is specified the library automatically ensures that the super class type is (initially) set to java.lang.Object as required by the JVM specification.

This package in particular provides functionality to convert org.opalj.br classes to org.opalj.da classes.

  1. final class AccessModifier extends AnyVal

    Permalink

    Represents the access flags of a class, method or field declaration.

    Represents the access flags of a class, method or field declaration.

    All standard access flags are predefined.

    Example:

    1. To create a class file's, a field's or a method's access modifier, you can chain them using post fix notation, e.g.:

      PUBLIC FINAL

      or you just append the using '.', e.g.:

      PUBLIC.FINAL.SYNTHETIC.VARARGS

  2. case class AnnotatedInstructionElement[T](instruction: InstructionLike, annotation: T) extends InstructionLikeElement[T] with Product with Serializable

    Permalink

    Wrapper for annotated org.opalj.br.instructions.InstructionLikes.

  3. implicit final class BRConstantsBuffer extends AnyVal

  4. class CATCH extends PseudoInstruction with ExceptionHandlerElement

    Permalink

    Pseudo instruction marking the handler of a org.opalj.br.ExceptionHandler.

  5. class CLASS[T] extends AnyRef

    Builder for org.opalj.br.ClassFile objects.

  6. class CodeAttributeBuilder[T] extends br.CodeAttributeBuilder[(Map[PC, T], List[String])]

    Permalink

    Builder for the org.opalj.br.Code attribute with all its properties.

    Builder for the org.opalj.br.Code attribute with all its properties. Instantiation is only possible with the CODE factory. The max_stack and max_locals values will be calculated if not explicitly defined.

  7. trait CodeElement[+T] extends AnyRef

    Permalink

    Wrapper for elements that will generate the instructions and attributes of a org.opalj.br.Code and the annotations of the bytecode.

  8. case class EXCEPTIONS(exceptionTypes: String*) extends MethodAttributeBuilder with Product with Serializable

    Permalink

    Builder for the org.opalj.br.ExceptionTable attribute.

  9. trait ExceptionHandlerElement extends PseudoInstruction

    Permalink

    Pseudo instructions which generate the org.opalj.br.ExceptionHandler of the org.opalj.br.Code attribute.

    Pseudo instructions which generate the org.opalj.br.ExceptionHandler of the org.opalj.br.Code attribute. An ExceptionHandler is composed of the three pseudo instructions TRY, TRYEND and CATCH with the same identifier symbol. The exceptionHandler includes all instructions between TRY and TRYEND. The handlerPC is the pc of the instruction following the CATCH. If the label contains numbers at the end, the ExceptionHandlers are sorted ascending by that number in the ExceptionHandlerTable. Otherwise, the ExceptionHandlers are lexically sorted by their label.
