Constructor Detail

FlinkUARTInputStream

public FlinkUARTInputStream(FlinkUART uart)

Creates an input stream on a given UART interface.

Parameters:

uart - UART number.

Method Detail

available

public int available()

Returns the number of bytes available from the stream.

Overrides:

available in class UARTInputStream

Returns:

number of bytes available.

read

public int read()

Reads one byte from the UART. A call of this method is not blocking!

Overrides:

read in class UARTInputStream

Returns:

byte read

read

public int read(byte[] buffer)

Reads the given number of bytes from the UART. A call of this method is not blocking!

Overrides:

read in class UARTInputStream

Parameters:

buffer - Byte array to write the received data.

Returns:

the number of bytes read.

read

public int read(byte[] buffer,
                int off,
                int count)

Reads the given number of bytes from the UART. A call of this method is not blocking!

Overrides:

read in class UARTInputStream

Parameters:

buffer - Byte array to write the received data.

off - Offset in the array to start writing the data.

count - Length (number of bytes) to read.

Returns:

the number of bytes read.
