public void writeApplicationData(byte[] buf,
                                 int offset,

                          throws java.io.IOException

Write some application data. Fragmentation is handled internally. Usable in both blocking/non-blocking modes.

In blocking mode, the output will be automatically sent via the underlying transport. In non-blocking mode, call readOutput(byte[], int, int) to get the output bytes to send to the peer.

This method must not be called until after the initial handshake is complete. Attempting to call it earlier will result in an IllegalStateException.

Parameters:

buf - The buffer containing application data to send

offset - The offset at which the application data begins

len - The number of bytes of application data

Throws:

java.lang.IllegalStateException - If called before the initial handshake has completed.

java.io.IOException - If connection is already closed, or for encryption or transport errors.

getAppDataSplitMode

getOutputStream

public java.io.OutputStream getOutputStream()

Returns:

An OutputStream which can be used to send data. Only allowed in blocking mode.

getInputStream

public java.io.InputStream getInputStream()

Returns:

An InputStream which can be used to read data. Only allowed in blocking mode.

closeInput

public void closeInput()
                throws java.io.IOException

Should be called in non-blocking mode when the input data reaches EOF.

Throws:

java.io.IOException

previewInputRecord

public RecordPreview previewInputRecord(byte[] recordHeader)
                                 throws java.io.IOException

offerInput

public void offerInput(byte[] input)
                throws java.io.IOException

Equivalent to offerInput(input, 0, input.length)

Parameters:

input - The input buffer to offer

Throws:

java.io.IOException - If an error occurs while decrypting or processing a record

See Also:

offerInput(byte[], int, int)

offerInput

public void offerInput(byte[] input,
                       int inputOff,
                       int inputLen)
                throws java.io.IOException

Offer input from an arbitrary source. Only allowed in non-blocking mode.

This method will decrypt and process all records that are fully available. If only part of a record is available, the buffer will be retained until the remainder of the record is offered.

If any records containing application data were processed, the decrypted data can be obtained using readInput(byte[], int, int). If any records containing protocol data were processed, a response may have been generated. You should always check to see if there is any available output after calling this method by calling getAvailableOutputBytes().

Parameters:

input - The input buffer to offer

inputOff - The offset within the input buffer that input begins

inputLen - The number of bytes of input being offered

Throws:

java.io.IOException - If an error occurs while decrypting or processing a record

getApplicationDataLimit

public int getApplicationDataLimit()

getAvailableInputBytes

public int getAvailableInputBytes()

Gets the amount of received application data. A call to readInput(byte[], int, int) is guaranteed to be able to return at least this much data.

Only allowed in non-blocking mode.

Returns:

The number of bytes of available application data

readInput

public int readInput(byte[] buffer,
                     int offset,
                     int length)

Retrieves received application data. Use getAvailableInputBytes() to check how much application data is currently available. This method functions similarly to InputStream.read(byte[], int, int), except that it never blocks. If no data is available, nothing will be copied and zero will be returned.

Only allowed in non-blocking mode.

Parameters:

buffer - The buffer to hold the application data

offset - The start offset in the buffer at which the data is written

length - The maximum number of bytes to read

Returns:

The total number of bytes copied to the buffer. May be less than the length specified if the length was greater than the amount of available data.

getAvailableOutputBytes

public int getAvailableOutputBytes()

Gets the amount of encrypted data available to be sent. A call to readOutput(byte[], int, int) is guaranteed to be able to return at least this much data.

Only allowed in non-blocking mode.

Returns:

The number of bytes of available encrypted data

readOutput

public int readOutput(byte[] buffer,
                      int offset,
                      int length)

Retrieves encrypted data to be sent. Use getAvailableOutputBytes() to check how much encrypted data is currently available. This method functions similarly to InputStream.read(byte[], int, int), except that it never blocks. If no data is available, nothing will be copied and zero will be returned.

Only allowed in non-blocking mode.

Parameters:

buffer - The buffer to hold the encrypted data

offset - The start offset in the buffer at which the data is written

length - The maximum number of bytes to read

Returns:

The total number of bytes copied to the buffer. May be less than the length specified if the length was greater than the amount of available data.
