All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`int`	`available()`	Returns the number of bytes that can be read without blocking.
`void`	`close()`
`long`	`getRetainedSize()`	Approximate number of bytes retained by this instance.
`boolean`	`isReadable()`	Returns `true` if and only if `available()` is greater than `0`.
`long`	`position()`	Returns the `position` of this buffer.
`int`	`read()`
`int`	`read(byte[] destination, int destinationIndex, int length)`
`boolean`	`readBoolean()`	Returns true if the byte at the current `position` is not `0` and increases the `position` by `1` in this buffer.
`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`).
`void`	`readBytes(Slice 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`).
`void`	`readBytes(OutputStream out, int length)`	Transfers this buffer's data to the specified stream starting at the current `position`.
`double`	`readDouble()`	Gets a 64-bit double at the current `position` and increases the `position` by `8` in this buffer.
`float`	`readFloat()`	Gets a 32-bit float at the current `position` and increases the `position` by `4` in this buffer.
`int`	`readInt()`	Gets a 32-bit integer at the current `position` and increases the `position` by `4` in this buffer.
`long`	`readLong()`	Gets a 64-bit long at the current `position` and increases the `position` by `8` in this buffer.
`short`	`readShort()`	Gets a 16-bit short integer at the current `position` and increases the `position` by `2` in this buffer.
`Slice`	`readSlice(int length)`	Returns a new slice of this buffer's sub-region starting at the current `position` and increases the `position` by the size of the new slice (= `length`).
`int`	`readUnsignedByte()`	Gets an unsigned byte at the current `position` and increases the `position` by `1` in this buffer.
`int`	`readUnsignedShort()`	Gets an unsigned 16-bit short integer at the current `position` and increases the `position` by `2` in this buffer.
`void`	`setPosition(long position)`	Sets the `position` of this buffer.
`long`	`skip(long length)`
`int`	`skipBytes(int n)`
