public static interface PackedInts.Reader
A read-only random access array of positive integers.
Method Summary | |
---|---|
long |
get(int index)
|
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. |
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. |
int |
getBitsPerValue()
|
boolean |
hasArray()
Returns true if this implementation is backed by a native java array. |
long |
ramBytesUsed()
Return the in-memory size in bytes. |
int |
size()

long get(int index)
index
- the position of the wanted value.
int get(int index, long[] arr, int off, int len)
len
longs starting
from index
into arr[off:off+len]
and return
the actual number of values that have been read.
int getBitsPerValue()
bitsPerValue * #values
as implementations are free to
use non-space-optimal packing of bits.int size()
