Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`java.nio.ByteBuffer`	`buffer()`	Returns a useable buffer (i.e.
`default java.nio.FloatBuffer`	`floatBuffer()`
`default java.nio.IntBuffer`	`intBuffer()`
`long`	`offset()`	Position in the file of the start of the buffer.
`void`	`release()`	To be called when this buffer is no longer in use.

- Method Detail
  - buffer
```
java.nio.ByteBuffer buffer()
```
    Returns a useable buffer (i.e. one whose position and limit can be freely modified). Its limit will be set to the size of the available data in the buffer. The buffer must be treated as read-only.
  - floatBuffer
```
default java.nio.FloatBuffer floatBuffer()
```
  - intBuffer
```
default java.nio.IntBuffer intBuffer()
```
  - offset
```
long offset()
```
    Position in the file of the start of the buffer.
  - release
```
void release()
```
    To be called when this buffer is no longer in use. Must be called for all BufferHolders, or ChunkCache will not be able to free blocks.
