Class AnnotationNode

java.lang.Object
org.objectweb.asm.AnnotationVisitor
org.objectweb.asm.tree.AnnotationNode
Direct Known Subclasses:
TypeAnnotationNode
public class AnnotationNode extends AnnotationVisitor
A node that represents an annotation.

  • Field Details

    • desc

      public String desc
      The class descriptor of the annotation class.

    • values

      public List<Object> values
      The name value pairs of this annotation. Each name value pair is stored as two consecutive elements in the list. The name is a String, and the value may be a Byte, Boolean, Character, Short, Integer, Long, Float, Double, String or Type, or a two elements String array (for enumeration values), an AnnotationNode, or a List of values of one of the preceding types. The list may be null if there is no name value pair.

  • Constructor Details

    • AnnotationNode

      public AnnotationNode(String descriptor)
      Constructs a new AnnotationNode. Subclasses must not use this constructor. Instead, they must use the AnnotationNode(int, String) version.
      Parameters:
      descriptor - the class descriptor of the annotation class.
      Throws:
      IllegalStateException - If a subclass calls this constructor.

    • AnnotationNode

      public AnnotationNode(int api, String descriptor)
      Constructs a new AnnotationNode.
      Parameters:
      api - the ASM API version implemented by this visitor. Must be one of the ASMx values in Opcodes.
      descriptor - the class descriptor of the annotation class.

  • 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 of Type.OBJECT or Type.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 AnnotationVisitor.visitArray(java.lang.String) and visiting each array element in turn, but is more convenient).

    • visitEnum

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

    • visitAnnotation

      public AnnotationVisitor visitAnnotation(String name, String descriptor)
      Description copied from class: AnnotationVisitor
      Visits a nested annotation value of the annotation.
      Overrides:
      visitAnnotation in class AnnotationVisitor
      Parameters:
      name - the value name.
      descriptor - 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 values (such as byte, boolean, short, char, int, long, float or double) can be passed as value to visit. This is what ClassReader does for non empty arrays of primitive values.
      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

    • check

      public void check(int api)
      Checks that this annotation node is compatible with the given ASM API version. This method checks that this node, and all its children recursively, do not contain elements that were introduced in more recent versions of the ASM API than the given version.
      Parameters:
      api - an ASM API version. Must be one of the ASMx values in Opcodes.

    • accept

      public void accept(AnnotationVisitor annotationVisitor)
      Makes the given visitor visit this annotation.
      Parameters:
      annotationVisitor - an annotation visitor. Maybe null.
