  - getValidator
```
public Validator<? super V> getValidator()
```
    Specified by:
    
    getValidator in interface PropertyMetadata<V>
    
    Returns:
    
    the Validator used to validate the property.
  - getExpression
```
public Supplier<? extends V> getExpression()
```
    Specified by:
    
    getExpression in interface PropertyMetadata<V>
    
    Returns:
    
    the optional Supplier that calculates the value dynamically. May be null for a regular property. If it is not null the property will automatically be read-only. You should not provide an explicit validator if you provide an expression.
  - getValueType
```
public Type getValueType()
```
    Specified by:
    
    getValueType in interface PropertyMetadata<V>
    
    Returns:
    
    the optional Type of the property value. May be null.

  - get
```
public Object get(String key)
```
    Specified by:
    
    get in interface PropertyMetadata<V>
    
    Parameters:
    
    key - the key of the requested metadata.
    
    Returns:
    
    the value of the metadata for the given key. Will be null if no metadata exists for the given key.
    
    See Also:
    
    PropertyMetadata.get(String, Class)
  - getKeys
```
public Iterable<String> getKeys()
```
    Specified by:
    
    getKeys in interface PropertyMetadata<V>
    
    Returns:
    
    the Iterable of all metadata keys.
  - getKeyCount
```
public int getKeyCount()
```
    Specified by:
    
    getKeyCount in interface PropertyMetadata<V>
    
    Returns:
    
    the size of the key/ value pairs in this map.
  - asMap
```
public Map<String,Object> asMap()
```
    Specified by:
    
    asMap in interface PropertyMetadata<V>
    
    Returns:
    
    a new or immutable Map with this metadata key/value pairs.
