  - isCollectionType
```
public boolean isCollectionType()
```
    从接口复制的说明: Type
    
    Return true if the implementation is castable to CollectionType. Essentially a polymorphic version of (type instanceof CollectionType.class)
    A CollectionType is additionally an AssociationType; so if this method returns true, Type.isAssociationType() should also return true.
    
    指定者:
    
    isCollectionType 在接口中 Type
    
    覆盖:
    
    isCollectionType 在类中 AbstractType

    True if this type is also a CollectionType implementor; false otherwise.

```
public final boolean isEqual(Object x,
                             Object y)
```
    从接口复制的说明: Type
    
    Compare two instances of the class mapped by this type for persistence "equality" (equality of persistent state).
    This should always equate to some form of comparison of the value's internal state. As an example, for something like a date the comparison should be based on its internal "time" state based on the specific portion it is meant to represent (timestamp, date, time).
    
    指定者:
    
    isEqual 在接口中 Type
    
    覆盖:
    
    isEqual 在类中 AbstractType
    
    参数:
    
    x - The first value
    
    y - The second value

    指定者:
    
    compare 在接口中 Type
    
    覆盖:
    
    compare 在类中 AbstractType
    
    参数:
    
    x - The first value
    
    y - The second value
    
    返回:
    
    The comparison result. See Comparator.compare(T, T) for a discussion.
  - getHashCode
```
public int getHashCode(Object x)
```
    从接口复制的说明: Type
    
    Get a hash code, consistent with persistence "equality". Again for most types the normal usage is to delegate to the value's hashCode.
    
    指定者:
    
    getHashCode 在接口中 Type
    
    覆盖:
    
    getHashCode 在类中 AbstractType
