  - ### Method Detail

    - #### public void addMember(String name, Expression value)

    - #### public ClassNode getClassNode()

    - #### public Expression getMember(String name)

    - #### public Map<String, Expression> getMembers()

    - #### public boolean hasClassRetention()

      Flag corresponding to `RetentionPolicy.CLASS`.

      Returns:
        `true` if the annotation is recorded by the compiler, but not visible at runtime * `false` otherwise

    - #### public boolean hasRuntimeRetention()

      Flag corresponding to `RetentionPolicy`.

      Returns:
        `true` if the annotation should be visible at runtime, `false` otherwise

    - #### public boolean hasSourceRetention()

      Flag corresponding to `RetentionPolicy.SOURCE`.

      Returns:
        `true` if the annotation is only allowed in sources `false` otherwise

    - #### public boolean isBuiltIn()

    - #### public boolean isTargetAllowed(int target)

    - #### public void setAllowedTargets(int bitmap)

    - #### public void setClassRetention(boolean flag)

      Sets the internal flag if the current annotation has `RetentionPolicy.CLASS`.

    - #### public void setMember(String name, Expression value)

    - #### public void setRuntimeRetention(boolean flag)

      Sets the internal flag of this annotation runtime retention policy. If the current annotation has `RetentionPolicy.RUNTIME` or if `false` if the `RetentionPolicy.CLASS`.

      Parameters:
        `flag` - if `true` then current annotation is marked as having `RetentionPolicy.RUNTIME`. If `false` then the annotation has `RetentionPolicy.CLASS`.

    - #### public void setSourceRetention(boolean flag)

      Sets the internal flag if the current annotation has `RetentionPolicy.SOURCE`.

    - #### public static String targetToName(int target)
