方法详细资料

isRepeatable

public boolean isRepeatable()

从接口复制的说明: HttpEntity

Tells if the entity is capable of producing its data more than once. A repeatable entity's getContent() and writeTo(OutputStream) methods can be called more than once whereas a non-repeatable entity's can not.

指定者:

isRepeatable 在接口中 HttpEntity

返回:

true if the entity is repeatable, false otherwise.

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

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

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()

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

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()

Tells that this entity is not streaming.

指定者:

isStreaming 在接口中 HttpEntity

返回:

false

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

覆盖:

clone 在类中 java.lang.Object

抛出:

java.lang.CloneNotSupportedException
