BufferAccess

All Superinterfaces:

ArrayDataAccess<A>, DataAccess, java.io.Serializable, VolatileAccess

All Known Implementing Classes:

AbstractBufferAccess, ByteBufferAccess, CharBufferAccess, DoubleBufferAccess, FloatBufferAccess, IntBufferAccess, LongBufferAccess, ShortBufferAccess
```
public interface BufferAccess<A>
extends VolatileAccess, ArrayDataAccess<A>
```
BufferAccess wraps java.nio.Buffer subclasses and implements ArrayDataAccess and VolatileAccess. Subclasses should be able to be constructed from either a specific buffer (e.g. LongBuffer) or ByteBuffer.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`int`	`getNumBytesPerEntity()`	Get number of bytes for one entity in this `BufferAccess`.
`boolean`	`isDirect()`	Determine if the underlying Buffer is allocated direct (outside of the JVM).
`boolean`	`isReadOnly()`	Determine if data can be read only and not written
`A`	`newInstance(java.nio.ByteBuffer buffer, boolean isValid)`	Create a new instance from a ByteBuffer

- Method Detail
  - isDirect
```
boolean isDirect()
```
    Determine if the underlying Buffer is allocated direct (outside of the JVM).
    
    Returns:
    
    true if the Buffer is direct.
    
    See Also:
    
    Buffer.isDirect()
  - isReadOnly
```
boolean isReadOnly()
```
    Determine if data can be read only and not written
    
    Returns:
    
    See Also:
    
    Buffer.isReadOnly()
  - getNumBytesPerEntity
```
int getNumBytesPerEntity()
```
    Get number of bytes for one entity in this BufferAccess. This usually retrieves a static field.
    
    Returns:
    
    number of bytes
  - newInstance
```
A newInstance(java.nio.ByteBuffer buffer,
              boolean isValid)
```
    Create a new instance from a ByteBuffer
    
    Parameters:
    
    buffer -
    
    isValid -
    
    Returns:
