- Method Detail
  - getName
```
String getName()
```
    Returns the name of the Property.
    
    Returns:
    the Property name.
  - getType
```
Type getType()
```
    Returns the type of the Property.
    
    Returns:
    the Property type.
  - isMany
```
boolean isMany()
```
    Returns whether the Property is many-valued.
    
    Returns:
    true if the Property is many-valued.
  - isContainment
```
boolean isContainment()
```
    Returns whether the Property is containment, i.e., whether it represents by-value composition.
    
    Returns:
    true if the Property is containment.
  - getContainingType
```
Type getContainingType()
```
    Returns the containing type of this Property.
    
    Returns:
    the Property's containing type.
    See Also:
    Type.getProperties()
  - getDefault
```
Object getDefault()
```
    Returns the default value this Property will have in a data object where the Property hasn't been set.
    
    Returns:
    the default value.
  - isReadOnly
```
boolean isReadOnly()
```
    Returns true if values for this Property cannot be modified using the SDO APIs. When true, DataObject.set(Property property, Object value) throws an exception. Values may change due to other factors, such as services operating on DataObjects.
    
    Returns:
    true if values for this Property cannot be modified.
  - getOpposite
```
Property getOpposite()
```
    Returns the opposite Property if the Property is bi-directional or null otherwise.
    
    Returns:
    the opposite Property if the Property is bi-directional or null
  - getAliasNames
```
List<String> getAliasNames()
```
    Returns a list of alias names for this Property.
    
    Returns:
    a list of alias names for this Property.
  - isNullable
```
boolean isNullable()
```
    Returns whether or not instances of this property can be set to null. The effect of calling set(null) on a non-nullable property is not specified by SDO.
    
    Returns:
    true if this property is nullable.
  - isOpenContent
```
boolean isOpenContent()
```
    Returns whether or not this is an open content Property.
    
    Returns:
    true if this property is an open content Property.
  - getInstanceProperties
```
List getInstanceProperties()
```
    Returns a read-only List of instance Properties available on this Property.
    This list includes, at a minimum, any open content properties (extensions) added to the object before defining the Property's Type. Implementations may, but are not required to in the 2.1 version of SDO, provide additional instance properties.
    
    Returns:
    the List of instance Properties on this Property.
  - get
```
Object get(Property property)
```
    Returns the value of the specified instance property of this Property.
    
    Parameters:
    property - one of the properties returned by getInstanceProperties().
    
    Returns:
    the value of the specified property.
