Class InputStreamContent

java.lang.Object
  com.google.api.client.http.AbstractInputStreamContent
      com.google.api.client.http.InputStreamContent

All Implemented Interfaces:

HttpContent

public final class InputStreamContent
extends AbstractInputStreamContent

Concrete implementation of AbstractInputStreamContent that simply handles the transfer of data from an input stream to an output stream. This should only be used for streams that can not be re-opened and retried. If you have a stream that it is possible to recreate please create a new subclass of AbstractInputStreamContent.

The input stream is guaranteed to be closed at the end of AbstractInputStreamContent.writeTo(OutputStream).

Sample use with a URL:

 
  private static void setRequestJpegContent(HttpRequest request, URL jpegUrl) throws IOException {
    request.setContent(new InputStreamContent("image/jpeg", jpegUrl.openStream()));
  }
 
 

Implementation is not thread-safe.

1.0

Method Detail

getLength

public long getLength()

Description copied from interface: HttpContent

Returns the content length or less than zero if not known.

retrySupported

public boolean retrySupported()

Description copied from interface: HttpContent

Returns whether or not retry is supported on this content type.

getInputStream

public InputStream getInputStream()

Description copied from class: AbstractInputStreamContent

Return an input stream for the specific implementation type of AbstractInputStreamContent. If the specific implementation will return true for HttpContent.retrySupported() this should be a factory function which will create a new InputStream from the source data whenever invoked.

Specified by:

getInputStream in class AbstractInputStreamContent

setEncoding

public InputStreamContent setEncoding(String encoding)

Description copied from class: AbstractInputStreamContent

Sets the content encoding (for example "gzip") or null for none.

Overrides:

setEncoding in class AbstractInputStreamContent

setType

public InputStreamContent setType(String type)

Description copied from class: AbstractInputStreamContent

Sets the content type or null for none.

Overrides:

setType in class AbstractInputStreamContent

setLength

public void setLength(long length)

Sets the content length or less than zero if not known.

Defaults to -1.
