@SdkInternalApi
public class RepeatableInputStreamRequestEntity
extends org.apache.hc.core5.http.io.entity.HttpEntityWrapper

Custom implementation of HttpEntity that delegates to an InputStreamEntity, 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.

RepeatableInputStreamRequestEntity

public RepeatableInputStreamRequestEntity(HttpExecuteRequest request)

Method Detail

isChunked

public boolean isChunked()

Specified by:

isChunked in interface org.apache.hc.core5.http.EntityDetails

Overrides:

isChunked in class org.apache.hc.core5.http.io.entity.HttpEntityWrapper

isRepeatable

public boolean isRepeatable()

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

Specified by:

isRepeatable in interface org.apache.hc.core5.http.HttpEntity

Overrides:

isRepeatable in class org.apache.hc.core5.http.io.entity.HttpEntityWrapper

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.hc.core5.http.HttpEntity

Overrides:

writeTo in class org.apache.hc.core5.http.io.entity.HttpEntityWrapper

Throws:

IOException

close

public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class org.apache.hc.core5.http.io.entity.HttpEntityWrapper

Throws:

IOException
