int	position() Returns the position of this buffer.
int	read()
boolean	readBoolean()
byte	readByte() Gets a byte at the current position and increases the position by 1 in this buffer.
void	readBytes(byte[] destination, int destinationIndex, int length) Transfers this buffer's data to the specified destination starting at the current position and increases the position by the number of the transferred bytes (= length).

slice

public Slice slice()

Returns a slice of this buffer's readable bytes. Modifying the content of the returned buffer or this buffer affects each other's content while they maintain separate indexes and marks. This method is identical to buf.slice(buf.position(), buf.available()()). This method does not modify position or writerIndex of this buffer.

toString

public String toString(Charset charset)

Decodes this buffer's readable bytes into a string with the specified character set name. This method is identical to buf.toString(buf.position(), buf.available()(), charsetName). This method does not modify position or writerIndex of this buffer.

toString

public String toString()

Overrides:

toString in class Object
