方法概要

所有方法实例方法抽象方法具体方法
修饰符和类型	方法	说明
`void`	`close()`	Method for unregistering the current context - should always and only be used by in conjunction with a matching `register(Object)` to ensure that `getContext()` always returns the correct value.
`protected abstract void`	`close(C context)`
`protected abstract C`	`createNewContext(E execution, BatchPropertyContext propertyContext)`
`C`	`getContext()`	Getter for the current context if there is one, otherwise returns `null`.
`java.util.Stack<E>`	`getCurrent()`
`void`	`increment()`
`C`	`register(E execution)`	Register a context with the current thread - always put a matching `close()` call in a finally block to ensure that the correct context is available in the enclosing block.
`C`	`register(E execution, BatchPropertyContext propertyContext)`	Register a context with the current thread - always put a matching `close()` call in a finally block to ensure that the correct context is available in the enclosing block.
`void`	`release()`	A convenient "deep" close operation.

public SynchronizationManagerSupport()
```

  - getContext
```
@Nullable
public C getContext()
```
    Getter for the current context if there is one, otherwise returns null.
    返回:
    the current context or null if there is none (if one has not been registered for this thread).
  - register
```
@Nullable
public C register(@Nullable
                  E execution)
```
    Register a context with the current thread - always put a matching close() call in a finally block to ensure that the correct context is available in the enclosing block.
    参数:
    execution - the execution to register
    返回:
    a new context or the current one if it has the same execution
  - register
```
@Nullable
public C register(@Nullable
                  E execution,
                  @Nullable
                  BatchPropertyContext propertyContext)
```
    Register a context with the current thread - always put a matching close() call in a finally block to ensure that the correct context is available in the enclosing block.
    参数:
    execution - the execution to register
    propertyContext - instance of BatchPropertyContext to be registered with this thread.
    返回:
    a new context or the current one if it has the same execution
  - close
```
public void close()
```
    Method for unregistering the current context - should always and only be used by in conjunction with a matching register(Object) to ensure that getContext() always returns the correct value. Does not call close on the context - that is left up to the caller because he has a reference to the context (having registered it) and only he has knowledge of when the execution actually ended.
  - increment
```
public void increment()
```
  - getCurrent
```
public java.util.Stack<E> getCurrent()
```
  - release
```
public void release()
```
    A convenient "deep" close operation. Call this instead of close() if the execution for the current context is ending. Delegates to close(Object) and then ensures that close() is also called in a finally block.
  - close
```
protected abstract void close(C context)
```
  - createNewContext
```
protected abstract C createNewContext(E execution,
                                      @Nullable
                                      BatchPropertyContext propertyContext)
```
