AbstractClassicEntityProducer (aliyun-http-apache 0.2.0-beta API)

java.lang.Object
- org.apache.hc.core5.http.nio.support.classic.AbstractClassicEntityProducer

所有已实现的接口:

EntityDetails, AsyncDataProducer, AsyncEntityProducer, ResourceHolder
```
public abstract class AbstractClassicEntityProducer
extends Object
implements AsyncEntityProducer
```
AsyncEntityProducer implementation that acts as a compatibility layer for classic OutputStream based interfaces. Blocking output processing is executed through an Executor.

从以下版本开始:

  - produceData
```
protected abstract void produceData(ContentType contentType,
                                    OutputStream outputStream)
                             throws IOException
```
    Writes out entity data into the given stream.
    
    参数:
    
    contentType - the entity content type
    
    outputStream - the output stream
    
    抛出:
    
    IOException
  - isRepeatable
```
public final boolean isRepeatable()
```
    从接口复制的说明: AsyncEntityProducer
    
    Determines whether the producer can consistently produce the same content after invocation of ResourceHolder.releaseResources().
    
    指定者:
    
    isRepeatable 在接口中 AsyncEntityProducer
  - available
```
public final int available()
```
    从接口复制的说明: AsyncDataProducer
    
    Returns the number of bytes immediately available for output. This method can be used as a hint to control output events of the underlying I/O session.
    
    指定者:
    
    available 在接口中 AsyncDataProducer
    
    返回:
    
    the number of bytes immediately available for output
  - produce
```
public final void produce(DataStreamChannel channel)
                   throws IOException
```
    从接口复制的说明: AsyncDataProducer
    
    Triggered to signal the ability of the underlying data channel to accept more data. The data producer can choose to write data immediately inside the call or asynchronously at some later point.
    
    指定者:
    
    produce 在接口中 AsyncDataProducer
    
    参数:
    
    channel - the data channel capable to accepting more data.
    
    抛出:
    
    IOException
  - getContentLength
```
public final long getContentLength()
```
    从接口复制的说明: EntityDetails
    
    Returns length of the entity, if known.
    
    指定者:
    
    getContentLength 在接口中 EntityDetails
  - getContentType
```
public final String getContentType()
```
    从接口复制的说明: EntityDetails
    
    Returns content type of the entity, if known.
    
    指定者:
    
    getContentType 在接口中 EntityDetails
  - getContentEncoding
```
public String getContentEncoding()
```
    从接口复制的说明: EntityDetails
    
    Returns content encoding of the entity, if known.
    
    指定者:
    
    getContentEncoding 在接口中 EntityDetails
  - isChunked
```
public final boolean isChunked()
```
    从接口复制的说明: EntityDetails
    
    Returns chunked transfer hint for this entity.
    The behavior of wrapping entities is implementation dependent, but should respect the primary purpose.
    
    指定者:
    
    isChunked 在接口中 EntityDetails
  - getTrailerNames
```
public final Set<String> getTrailerNames()
```
    从接口复制的说明: EntityDetails
    
    Preliminary declaration of trailing headers.
    
    指定者:
    
    getTrailerNames 在接口中 EntityDetails
  - failed
```
public final void failed(Exception cause)
```
    从接口复制的说明: AsyncEntityProducer
    
    Triggered to signal a failure in data generation.
    
    指定者:
    
    failed 在接口中 AsyncEntityProducer
    
    参数:
    
    cause - the cause of the failure.

  - releaseResources
```
public void releaseResources()
```
    指定者:
    
    releaseResources 在接口中 ResourceHolder
