Method Summary

All Methods Instance Methods Abstract Methods Concrete Methods
Modifier and Type	Method	Description
`int`	`get(int index, long[] arr, int off, int len)`	Bulk get: read at least one and at most `len` longs starting from `index` into `arr[off:off+len]` and return the actual number of values that have been read.
`java.lang.Object`	`getArray()`	Expert: if the bit-width of this reader matches one of java's native types, returns the underlying array (ie, byte[], short[], int[], long[]); else, returns null.
`abstract int`	`getBitsPerValue()`
`boolean`	`hasArray()`	Returns true if this implementation is backed by a native java array.
`abstract long`	`ramBytesUsed()`	Return the in-memory size in bytes.
`abstract int`	`size()`

  - get
```
public int get(int index,
               long[] arr,
               int off,
               int len)
```
    Bulk get: read at least one and at most len longs starting from index into arr[off:off+len] and return the actual number of values that have been read.
  - getBitsPerValue
```
public abstract int getBitsPerValue()
```
    Returns:
    
    the number of bits used to store any given value. Note: This does not imply that memory usage is bitsPerValue * #values as implementations are free to use non-space-optimal packing of bits.
  - size
```
public abstract int size()
```
    Returns:
    
    the number of values.
  - ramBytesUsed
```
public abstract long ramBytesUsed()
```
    Return the in-memory size in bytes.
  - getArray
```
public java.lang.Object getArray()
```
    Expert: if the bit-width of this reader matches one of java's native types, returns the underlying array (ie, byte[], short[], int[], long[]); else, returns null. Note that when accessing the array you must upgrade the type (bitwise AND with all ones), to interpret the full value as unsigned. Ie, bytes[idx]&0xFF, shorts[idx]&0xFFFF, etc.
  - hasArray
```
public boolean hasArray()
```
    Returns true if this implementation is backed by a native java array.
