Method Detail

send

void send(String content)
          throws IOException

Sends a UTF-8 encoded string to the stream.

Parameters:

content - Data to be sent.

Throws:

IOException - If there is error writing to the stream.

send

void send(byte[] content)
          throws IOException

Sends a byte array to the stream. Same as calling send(content, 0, content.length).

Parameters:

content - Data to be sent.

Throws:

IOException - If there is error writing to the stream.

send

void send(byte[] content,
        int off,
        int len)
          throws IOException

Sends a byte array to the stream.

Parameters:

content - Data to be sent.

off - Offset in the array to start with

len - Number of bytes to sent starting from off.

Throws:

IOException - If there is error writing to the stream.

send

void send(ByteBuffer buffer)
          throws IOException

Sends the content of a ByteBuffer to the stream.

Parameters:

buffer - Data to be sent.

Throws:

IOException - If there is error writing to the stream.

send

void send(Map<String,String> headers,
        String content)
          throws IOException

Sends a UTF-8 encoded string to the stream.

Parameters:

headers - Key-value pairs to be sent as headers of StreamEvent.

content - Data to be sent.

Throws:

IOException - If there is error writing to the stream.

send

void send(Map<String,String> headers,
        byte[] content)
          throws IOException

Sends a byte array to the stream. Same as calling send(content, 0, content.length).

Parameters:

headers - Key-value pairs to be sent as headers of StreamEvent.

content - Data to be sent.

Throws:

IOException - If there is error writing to the stream.

send

void send(Map<String,String> headers,
        byte[] content,
        int off,
        int len)
          throws IOException

Sends a byte array to the stream.

Parameters:

headers - Key-value pairs to be sent as headers of StreamEvent.

content - Data to be sent.

off - Offset in the array to start with

len - Number of bytes to sent starting from off.

Throws:

IOException - If there is error writing to the stream.

send

void send(Map<String,String> headers,
        ByteBuffer buffer)
          throws IOException

Sends the content of a ByteBuffer to the stream.

Parameters:

headers - Key-value pairs to be sent as headers of StreamEvent.

buffer - Data to be sent.

Throws:

IOException - If there is error writing to the stream.
