Annotation (zk 10.0.0 API)

All Superinterfaces:

java.io.Serializable
```
public interface Annotation
extends java.io.Serializable
```
The common interface extended by all annotation types. An annotation consists of a name (getName()) and a map of attributes getAttribute(java.lang.String).
To get the annotation associated with a component, use ComponentCtrl.getAnnotations(String). To get the annotation associated with a component's property, use ComponentCtrl.getAnnotation(String, String)

- Method Detail
  - getName
```
java.lang.String getName()
```
    Returns the name of this annotation.
    For each declaration, there is at most one annotation with the same name.
  - getAttributes
```
java.util.Map<java.lang.String,java.lang.String[]> getAttributes()
```
    Returns the map of attributes(never null). The key is a String instance, while the value is an array of String instances (length might be zero, but it is never null).
    The returned map is read-only.
  - getAttribute
```
java.lang.String getAttribute(java.lang.String name)
```
    Returns the first value of the given attribute, or null if not found. By the first value we mean the first element in the value array.
  - getAttributeValues
```
java.lang.String[] getAttributeValues(java.lang.String name)
```
    Returns all values of the given attribute, or null if not found. Notice if the attribute is assigned with no value, a zero-length array is returned.
