Class AnnotationWriter

java.lang.Object
org.eclipse.sisu.space.asm.AnnotationVisitor
org.eclipse.sisu.space.asm.AnnotationWriter

final class AnnotationWriter extends AnnotationVisitor
An AnnotationVisitor that generates annotations in bytecode form.
  • Field Details

    • cw

      private final ClassWriter cw
      The class writer to which this annotation must be added.
    • size

      private int size
      The number of values in this annotation.
    • named

      private final boolean named
      true if values are named, false otherwise. Annotation writers used for annotation default and annotation arrays use unnamed values.
    • bv

      private final ByteVector bv
      The annotation values in bytecode form. This byte vector only contains the values themselves, i.e. the number of values must be stored as a unsigned short just before these bytes.
    • parent

      private final ByteVector parent
      The byte vector to be used to store the number of values of this annotation. See bv.
    • offset

      private final int offset
      Where the number of values of this annotation must be stored in parent.
    • next

      Next annotation writer. This field is used to store annotation lists.
    • prev

      Previous annotation writer. This field is used to store annotation lists.
  • Constructor Details

    • AnnotationWriter

      AnnotationWriter(ClassWriter cw, boolean named, ByteVector bv, ByteVector parent, int offset)
      Constructs a new AnnotationWriter.
      Parameters:
      cw - the class writer to which this annotation must be added.
      named - true if values are named, false otherwise.
      bv - where the annotation values must be stored.
      parent - where the number of annotation values must be stored.
      offset - where in parent the number of annotation values must be stored.
  • Method Details

    • visit

      public void visit(String name, Object value)
      Description copied from class: AnnotationVisitor
      Visits a primitive value of the annotation.
      Overrides:
      visit in class AnnotationVisitor
      Parameters:
      name - the value name.
      value - the actual value, whose type must be Byte, Boolean, Character, Short, Integer , Long, Float, Double, String or Type or OBJECT or ARRAY sort. This value can also be an array of byte, boolean, short, char, int, long, float or double values (this is equivalent to using visitArray and visiting each array element in turn, but is more convenient).
    • visitEnum

      public void visitEnum(String name, String desc, String value)
      Description copied from class: AnnotationVisitor
      Visits an enumeration value of the annotation.
      Overrides:
      visitEnum in class AnnotationVisitor
      Parameters:
      name - the value name.
      desc - the class descriptor of the enumeration class.
      value - the actual enumeration value.
    • visitAnnotation

      public AnnotationVisitor visitAnnotation(String name, String desc)
      Description copied from class: AnnotationVisitor
      Visits a nested annotation value of the annotation.
      Overrides:
      visitAnnotation in class AnnotationVisitor
      Parameters:
      name - the value name.
      desc - the class descriptor of the nested annotation class.
      Returns:
      a visitor to visit the actual nested annotation value, or null if this visitor is not interested in visiting this nested annotation. The nested annotation value must be fully visited before calling other methods on this annotation visitor.
    • visitArray

      public AnnotationVisitor visitArray(String name)
      Description copied from class: AnnotationVisitor
      Visits an array value of the annotation. Note that arrays of primitive types (such as byte, boolean, short, char, int, long, float or double) can be passed as value to visit. This is what ClassReader does.
      Overrides:
      visitArray in class AnnotationVisitor
      Parameters:
      name - the value name.
      Returns:
      a visitor to visit the actual array value elements, or null if this visitor is not interested in visiting these values. The 'name' parameters passed to the methods of this visitor are ignored. All the array values must be visited before calling other methods on this annotation visitor.
    • visitEnd

      public void visitEnd()
      Description copied from class: AnnotationVisitor
      Visits the end of the annotation.
      Overrides:
      visitEnd in class AnnotationVisitor
    • getSize

      int getSize()
      Returns the size of this annotation writer list.
      Returns:
      the size of this annotation writer list.
    • put

      void put(ByteVector out)
      Puts the annotations of this annotation writer list into the given byte vector.
      Parameters:
      out - where the annotations must be put.
    • put

      static void put(AnnotationWriter[] panns, int off, ByteVector out)
      Puts the given annotation lists into the given byte vector.
      Parameters:
      panns - an array of annotation writer lists.
      off - index of the first annotation to be written.
      out - where the annotations must be put.
    • putTarget

      static void putTarget(int typeRef, TypePath typePath, ByteVector out)
      Puts the given type reference and type path into the given bytevector. LOCAL_VARIABLE and RESOURCE_VARIABLE target types are not supported.
      Parameters:
      typeRef - a reference to the annotated type. See TypeReference.
      typePath - the path to the annotated type argument, wildcard bound, array element type, or static inner type within 'typeRef'. May be null if the annotation targets 'typeRef' as a whole.
      out - where the type reference and type path must be put.
