Method Detail

getErrorStream

protected InputStream getErrorStream()
                              throws IOException

Get the error stream from the connection.

Specified by:

getErrorStream in class AbfsHttpOperation

Returns:

InputStream

Throws:

IOException - if the error stream could not be created from the response stream.

processResponse

public void processResponse(byte[] buffer,
                            int offset,
                            int length)
                     throws IOException

Gets and processes the HTTP response.

Specified by:

processResponse in class AbfsHttpOperation

Parameters:

buffer - a buffer to hold the response entity body

offset - an offset in the buffer where the data will being.

length - the number of bytes to be written to the buffer.

Throws:

IOException - if an error occurs.

setRequestProperty

public void setRequestProperty(String key,
                               String value)

Set request header.

Specified by:

setRequestProperty in class AbfsHttpOperation

Parameters:

key - header key.

value - header value.

getResponseHeader

public String getResponseHeader(String headerName)

Get response header value for the given headerKey.

Specified by:

getResponseHeader in class AbfsHttpOperation

Parameters:

headerName - header key.

Returns:

header value.

getContentInputStream

protected InputStream getContentInputStream()

Get the response stream from the connection.

Specified by:

getContentInputStream in class AbfsHttpOperation

Returns:

InputStream: response stream from the connection after network call.

Throws:

IOException - if the response stream could not be created from the connection.

sendPayload

public void sendPayload(byte[] buffer,

Sends the HTTP request. Note that HttpUrlConnection requires that an empty buffer be sent in order to set the "Content-Length: 0" header, which is required by our endpoint.

Specified by:

sendPayload in class AbfsHttpOperation

Parameters:

buffer - the request entity body.

offset - an offset into the buffer where the data beings.

length - the length of the data in the buffer.

Throws:

IOException - if an error occurs.

getRequestProperty

public String getRequestProperty(String name)

Get request header value for a header name.

Parameters:

name - header name.

Returns:

header value.

getTracingContextSuffix

public String getTracingContextSuffix()
