Method from org.springframework.core.AttributeAccessor Summary:
attributeNames, getAttribute, hasAttribute, removeAttribute, setAttribute

Method from org.springframework.core.AttributeAccessor Detail:
public String[] attributeNames() Return the names of all attributes.
public Object getAttribute(String name) Get the value of the attribute identified by `name`. Return `null` if the attribute doesn't exist.
public boolean hasAttribute(String name) Return `true` if the attribute identified by `name` exists. Otherwise return `false`.
public Object removeAttribute(String name) Remove the attribute identified by `name` and return its value. Return `null` if no attribute under `name` is found.
public void setAttribute(String name, Object value) Set the attribute defined by `name` to the supplied `value`. If `value` is `null`, the attribute is removed . In general, users should take care to prevent overlaps with other metadata attributes by using fully-qualified names, perhaps using class or package names as prefix.
