所有已实现的接口:

HttpEntity

@NotThreadSafe
public class BufferedHttpEntity
extends HttpEntityWrapper

A wrapping entity that buffers it content if necessary. The buffered entity is always repeatable. If the wrapped entity is repeatable itself, calls are passed through. If the wrapped entity is not repeatable, the content is read into a buffer once and provided from there as often as required.

BufferedHttpEntity

public BufferedHttpEntity(HttpEntity entity)
                   throws java.io.IOException

Creates a new buffered entity wrapper.

参数:

entity - the entity to wrap, not null

抛出:

java.lang.IllegalArgumentException - if wrapped is null

java.io.IOException

方法详细资料

getContentLength

public long getContentLength()

从接口复制的说明: HttpEntity

Tells the length of the content, if known.

指定者:

getContentLength 在接口中 HttpEntity

覆盖:

getContentLength 在类中 HttpEntityWrapper

返回:

the number of bytes of the content, or a negative number if unknown. If the content length is known but exceeds Long.MAX_VALUE, a negative number is returned.

getContent

public java.io.InputStream getContent()
                               throws java.io.IOException

从接口复制的说明: HttpEntity

Returns a content stream of the entity. Repeatable entities are expected to create a new instance of InputStream for each invocation of this method and therefore can be consumed multiple times. Entities that are not repeatable are expected to return the same InputStream instance and therefore may not be consumed more than once.

IMPORTANT: Please note all entity implementations must ensure that all tlb resources are properly deallocated after the InputStream.close() method is invoked.

指定者:

getContent 在接口中 HttpEntity

覆盖:

getContent 在类中 HttpEntityWrapper

返回:

content stream of the entity.

抛出:

java.io.IOException - if the stream could not be created

另请参阅:

HttpEntity.isRepeatable()

isChunked

public boolean isChunked()

Tells that this entity does not have to be chunked.

指定者:

isChunked 在接口中 HttpEntity

覆盖:

isChunked 在类中 HttpEntityWrapper

返回:

false

isRepeatable

public boolean isRepeatable()

Tells that this entity is repeatable.

指定者:

isRepeatable 在接口中 HttpEntity

覆盖:

isRepeatable 在类中 HttpEntityWrapper

返回:

true

writeTo

public void writeTo(java.io.OutputStream outstream)
             throws java.io.IOException

从接口复制的说明: HttpEntity

Writes the entity content out to the output stream.

IMPORTANT: Please note all entity implementations must ensure that all tlb resources are properly deallocated when this method returns.

指定者:

writeTo 在接口中 HttpEntity

覆盖:

writeTo 在类中 HttpEntityWrapper

参数:

outstream - the output stream to write entity content to

抛出:

java.io.IOException - if an I/O error occurs

isStreaming

public boolean isStreaming()

从接口复制的说明: HttpEntity

Tells whether this entity depends on an underlying stream. Streamed entities that read data directly from the socket should return true. Self-contained entities should return false. Wrapping entities should delegate this call to the wrapped entity.

指定者:

isStreaming 在接口中 HttpEntity

覆盖:

isStreaming 在类中 HttpEntityWrapper

返回:

true if the entity content is streamed, false otherwise
