All Implemented Interfaces:

org.apache.http.HttpEntity

public class RepeatableInputStreamRequestEntity
extends org.apache.http.entity.BasicHttpEntity

Custom implementation of HttpEntity that delegates to an RepeatableInputStreamRequestEntity, with the one notable difference, that if the underlying InputStream supports being reset, this RequestEntity will report that it is repeatable and will reset the stream on all subsequent attempts to write out the request.

Constructor and Description
RepeatableInputStreamRequestEntity(HttpExecuteRequest request) Creates a new RepeatableInputStreamRequestEntity using the information from the specified request.

Method Summary

Modifier and Type	Method and Description
boolean	isChunked()
boolean	isRepeatable() Returns true if the underlying InputStream supports marking/reseting or if the underlying InputStreamRequestEntity is repeatable.
void	writeTo(OutputStream output) Resets the underlying InputStream if this isn't the first attempt to write out the request, otherwise simply delegates to InputStreamRequestEntity to write out the data.

Constructor Detail

RepeatableInputStreamRequestEntity

public RepeatableInputStreamRequestEntity(HttpExecuteRequest request)

Creates a new RepeatableInputStreamRequestEntity using the information from the specified request. If the input stream containing the request's contents is repeatable, then this RequestEntity will report as being repeatable.

Parameters:

request - The details of the request being written out (content type, content length, and content).

Method Detail

isChunked

public boolean isChunked()

Specified by:

isChunked in interface org.apache.http.HttpEntity

Overrides:

isChunked in class org.apache.http.entity.AbstractHttpEntity

isRepeatable

public boolean isRepeatable()

Returns true if the underlying InputStream supports marking/reseting or if the underlying InputStreamRequestEntity is repeatable.

Specified by:

isRepeatable in interface org.apache.http.HttpEntity

Overrides:

isRepeatable in class org.apache.http.entity.BasicHttpEntity

writeTo

public void writeTo(OutputStream output)
             throws IOException

Resets the underlying InputStream if this isn't the first attempt to write out the request, otherwise simply delegates to InputStreamRequestEntity to write out the data.

If an error is encountered the first time we try to write the request entity, we remember the original exception, and report that as the root cause if we continue to encounter errors, rather than masking the original error.

Specified by:

writeTo in interface org.apache.http.HttpEntity

Overrides:

writeTo in class org.apache.http.entity.BasicHttpEntity

Throws:

IOException
