Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`byte[]`	`array()`	Gets the backing array for this buffer.
`int`	`arrayOffset()`	Gets the offset in the backing array of the current read position.
`boolean`	`byteBufferSupported()`	Indicates whether or not `ReadableBuffer.getByteBuffer()` operation is supported for this buffer.
`protected void`	`checkReadable(int length)`
`void`	`close()`	Closes this buffer and releases any resources.
`java.nio.ByteBuffer`	`getByteBuffer()`	Gets a `ByteBuffer` that contains some bytes of the content next to be read, or `null` if this buffer has been exhausted.
`boolean`	`hasArray()`	Indicates whether or not this buffer exposes a backing array.
`void`	`mark()`	Marks the current position in this buffer.
`boolean`	`markSupported()`	Indicates whether or not `ReadableBuffer.mark()` operation is supported for this buffer.
`int`	`readInt()`	Reads a 4-byte signed integer from this buffer using big-endian byte ordering.
`void`	`reset()`	Repositions this buffer to the position at the time `ReadableBuffer.mark()` was last called on this buffer.

public AbstractReadableBuffer()

- Method Detail
  - readInt
```
public final int readInt()
```
    Description copied from interface: ReadableBuffer
    
    Reads a 4-byte signed integer from this buffer using big-endian byte ordering. Increments the read position by 4.
    
    Specified by:
    
    readInt in interface ReadableBuffer
  - hasArray
```
public boolean hasArray()
```
    Description copied from interface: ReadableBuffer
    
    Indicates whether or not this buffer exposes a backing array.
    
    Specified by:
    
    hasArray in interface ReadableBuffer
  - array
```
public byte[] array()
```
    Description copied from interface: ReadableBuffer
    
    Gets the backing array for this buffer. This is an optional method, so callers should first check ReadableBuffer.hasArray().
    
    Specified by:
    
    array in interface ReadableBuffer
  - arrayOffset
```
public int arrayOffset()
```
    Description copied from interface: ReadableBuffer
    
    Gets the offset in the backing array of the current read position. This is an optional method, so callers should first check ReadableBuffer.hasArray()
    
    Specified by:
    
    arrayOffset in interface ReadableBuffer
  - markSupported
```
public boolean markSupported()
```
    Description copied from interface: ReadableBuffer
    
    Indicates whether or not ReadableBuffer.mark() operation is supported for this buffer.
    
    Specified by:
    
    markSupported in interface ReadableBuffer
  - mark
```
public void mark()
```
    Description copied from interface: ReadableBuffer
    
    Marks the current position in this buffer. A subsequent call to the ReadableBuffer.reset() method repositions this stream at the last marked position so that subsequent reads re-read the same bytes.
    
    Specified by:
    
    mark in interface ReadableBuffer
  - reset
```
public void reset()
```
    Description copied from interface: ReadableBuffer
    
    Repositions this buffer to the position at the time ReadableBuffer.mark() was last called on this buffer.
    
    Specified by:
    
    reset in interface ReadableBuffer
  - byteBufferSupported
```
public boolean byteBufferSupported()
```
    Description copied from interface: ReadableBuffer
    
    Indicates whether or not ReadableBuffer.getByteBuffer() operation is supported for this buffer.
    
    Specified by:
    
    byteBufferSupported in interface ReadableBuffer
  - getByteBuffer
```
public java.nio.ByteBuffer getByteBuffer()
```
    Description copied from interface: ReadableBuffer
    
    Gets a ByteBuffer that contains some bytes of the content next to be read, or null if this buffer has been exhausted. The number of bytes contained in the returned buffer is implementation specific. The position of this buffer is unchanged after calling this method. The returned buffer's content should not be modified, but the position, limit, and mark may be changed. Operations for changing the position, limit, and mark of the returned buffer does not affect the position, limit, and mark of this buffer. Buffers returned by this method have independent position, limit and mark. This is an optional method, so callers should first check ReadableBuffer.byteBufferSupported().
    
    Specified by:
    
    getByteBuffer in interface ReadableBuffer
  - close
```
public void close()
```
    Description copied from interface: ReadableBuffer
    
    Closes this buffer and releases any resources.
    
    Specified by:
    
    close in interface java.lang.AutoCloseable
    
    Specified by:
    
    close in interface java.io.Closeable
    
    Specified by:
    
    close in interface ReadableBuffer
  - checkReadable
