所有已实现的接口:
RequestCondition<RequestConditionHolder>
```
public final class RequestConditionHolder
extends AbstractRequestCondition<RequestConditionHolder>
```
A holder for a RequestCondition useful when the type of the request condition is not known ahead of time, e.g. custom condition. Since this class is also an implementation of RequestCondition, effectively it decorates the held request condition and allows it to be combined and compared with other request conditions in a type and null safe way.
When two RequestConditionHolder instances are combined or compared with each other, it is expected the conditions they hold are of the same type. If they are not, a ClassCastException is raised.

    Return the discrete items a request condition is composed of.
    For example URL patterns, HTTP request methods, param expressions, etc.
    指定者:
    getContent 在类中 AbstractRequestCondition<RequestConditionHolder>
    返回:
    a collection of objects (never null)

```
    从类复制的说明: AbstractRequestCondition
    The notation to use when printing discrete items of content.
    For example " || " for URL patterns or " && " for param expressions.
    指定者:

  - combine
```
public RequestConditionHolder combine(RequestConditionHolder other)
```
    Combine the request conditions held by the two RequestConditionHolder instances after making sure the conditions are of the same type. Or if one holder is empty, the other holder is returned.
    参数:
    other - the condition to combine with.
    返回:
    a request condition instance that is the result of combining the two condition instances.
  - getMatchingCondition
```
public RequestConditionHolder getMatchingCondition(HttpServletRequest request)
```
    Get the matching condition for the held request condition wrap it in a new RequestConditionHolder instance. Or otherwise if this is an empty holder, return the same holder instance.
    返回:
    a condition instance in case of a match or null otherwise.
  - compareTo
```
public int compareTo(RequestConditionHolder other,
                     HttpServletRequest request)
```
    Compare the request conditions held by the two RequestConditionHolder instances after making sure the conditions are of the same type. Or if one holder is empty, the other holder is preferred.
