- Method Detail
  - createProperty
```
default Property<P> createProperty(Bean bean)
```
    Creates a property that binds this meta-property to a specific bean.
    This method returns a Property instance that connects this meta-property to the specified bean. The result can be queried and passed around without further reference to the bean.
    
    Parameters:
    
    bean - the bean to create the property for, not null
    
    Returns:
    
    the property, not null
  - metaBean
```
MetaBean metaBean()
```
    Gets the meta-bean which owns this meta-property.
    Each meta-property is fully owned by a single bean.
    
    Returns:
    
    the meta-bean, not null
  - name
```
String name()
```
    Gets the property name.
    The JavaBean style methods getFoo() and setFoo() will lead to a property name of 'foo' and so on.
    
    Returns:
    
    the name of the property, not empty
  - declaringType
```
Class<?> declaringType()
```
    Get the type that declares the property, represented as a Class.
    This is the type of the bean where the property is declared.
    
    Returns:
    
    the type declaring the property, not null
  - propertyType
```
Class<P> propertyType()
```
    Get the type of the property represented as a Class.
    This is the type of the property. For example, the surname of a person would typically be a String.
    
    Returns:
    
    the type of the property, not null
  - propertyGenericType
```
Type propertyGenericType()
```
    Gets the generic types of the property.
    This provides access to the generic type declared in the source code.
    
    Returns:
    
    the full generic type of the property, unmodifiable, not null
  - style
```
PropertyStyle style()
```
    Gets the style of the property, such as read-only, read-write or write-only.
    Rather than testing against specific values, it is strongly recommended to call the helper methods on the returned style.
    
    Returns:
    
    the property style, not null
  - annotations
```
List<Annotation> annotations()
```
    Gets the annotations of the property.
    The annotations are queried from the property. This is typically accomplished by querying the annotations of the underlying instance variable however any strategy is permitted. If the implementation does not support annotations, an empty list will be returned.
    
    Returns:
    
    the annotations, unmodifiable, not null
  - annotation
```
default <A extends Annotation> A annotation(Class<A> annotationClass)
```
    Gets an annotation from the property.
    The annotations are queried from the property. This is typically accomplished by querying the annotations of the underlying instance variable however any strategy is permitted.
    
    Type Parameters:
    
    A - the annotation type
    
    Parameters:
    
    annotationClass - the annotation class to find, not null
    
    Returns:
    
    the annotation, not null
    
    Throws:
    
    NoSuchElementException - if the annotation is not found
  - annotationOpt
```
default <A extends Annotation> Optional<A> annotationOpt(Class<A> annotationClass)
```
    Finds an optional annotation from the property.
    The annotations are queried from the property. This is typically accomplished by querying the annotations of the underlying instance variable however any strategy is permitted.
    
    Type Parameters:
    
    A - the annotation type
    
    Parameters:
    
    annotationClass - the annotation class to find, not null
    
    Returns:
    
    the annotation, empty if not found

  - get
```
P get(Bean bean)
```
    Gets the value of the property for the specified bean.
    For a standard JavaBean, this is equivalent to calling getFoo() on the bean. Alternate implementations may perform any logic to obtain the value.
    
    Parameters:
    
    bean - the bean to query, not null
    
    Returns:
    
    the value of the property on the specified bean, may be null
    
    Throws:
    
    ClassCastException - if the bean is of an incorrect type
    
    UnsupportedOperationException - if the property is write-only
  - set
```
void set(Bean bean,
         Object value)
```
    Sets the value of the property on the specified bean.
    The value must be of the correct type for the property. For a standard JavaBean, this is equivalent to calling setFoo() on the bean. Alternate implementations may perform any logic to change the value.
    
    Parameters:
    
    bean - the bean to update, not null
    
    value - the value to set into the property on the specified bean, may be null
    
    Throws:
    
    ClassCastException - if the bean is of an incorrect type
    
    ClassCastException - if the value is of an invalid type for the property
    
    UnsupportedOperationException - if the property is read-only
    
    RuntimeException - if the value is rejected by the property (use appropriate subclasses)
  - put
```
default P put(Bean bean,
              Object value)
```
    Sets the value of the property on the associated bean and returns the previous value.
    The value must be of the correct type for the property. This is a combination of the get and set methods that matches the definition of put in a Map.
    
    Parameters:
    
    bean - the bean to update, not null
    
    value - the value to set into the property on the specified bean, may be null
    
    Returns:
    
    the old value of the property, may be null
    
    Throws:
    
    ClassCastException - if the bean is of an incorrect type
    
    ClassCastException - if the value is of an invalid type for the property
    
    UnsupportedOperationException - if the property is read-only
    
    RuntimeException - if the value is rejected by the property (use appropriate subclasses)
  - getString
```
default String getString(Bean bean)
```
    Gets the value of the property for the specified bean converted to a string.
    This converts the result of get(Bean) to a standard format string. Conversion uses Joda-Convert. Not all object types can be converted to a string, see Joda-Convert.
    For a standard JavaBean, this is equivalent to calling getFoo() on the bean. Alternate implementations may perform any logic to obtain the value.
    
    Parameters:
    
    bean - the bean to query, not null
    
    Returns:
    
    the value of the property on the specified bean, may be null
    
    Throws:
    
    ClassCastException - if the bean is of an incorrect type
    
    UnsupportedOperationException - if the property is write-only
    
    RuntimeException - if the value cannot be converted to a string (use appropriate subclasses)
  - getString

                         org.joda.convert.StringConvert stringConvert)
```

    This converts the result of get(Bean) to a standard format string using the supplied converter. Not all object types can be converted to a string, see Joda-Convert.
    For a standard JavaBean, this is equivalent to calling getFoo() on the bean. Alternate implementations may perform any logic to obtain the value.

                       String value)
```
