## Class PackedDataInput

- java.lang.Object
- - org.apache.lucene.util.packed.PackedDataInput

    public final class PackedDataInput
    extends Object

A `DataInput` wrapper to read unaligned, variable-length packed integers. This API is much slower than the `PackedInts` fixed-length API but can be convenient to save space.

See Also:
  `PackedDataOutput`
NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.

### Constructor Summary

Constructor and Description
`PackedDataInput(DataInput in)` Create a new instance that wraps `in`.

### Method Summary

All Methods Instance Methods Concrete Methods
`long` `readLong(int bitsPerValue)` Read the next long using exactly `bitsPerValue` bits.
`void` `skipToNextByte()` If there are pending bits (at most 7), they will be ignored and the next value will be read starting at the next byte.
