Interface PackedInts.Mutable

All Superinterfaces:

PackedInts.Reader

All Known Implementing Classes:

GrowableWriter

Enclosing class:

PackedInts

public static interface PackedInts.Mutable
extends PackedInts.Reader

A packed integer array that can be modified.

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

Method Summary

void	clear() Sets all values to 0.
void	fill(int fromIndex, int toIndex, long val) Fill the mutable from fromIndex (inclusive) to toIndex (exclusive) with val.
void	save(DataOutput out) Save this mutable into out.
void	set(int index, long value) Set the value at the given index in the array.
int	set(int index, long[] arr, int off, int len) Bulk set: set at least one and at most len longs starting at off in arr into this mutable, starting at index.

Method Detail

set

void set(int index,
         long value)

Set the value at the given index in the array.

Parameters:

index - where the value should be positioned.

value - a value conforming to the constraints set by the array.

set

int set(int index,
        long[] arr,
        int off,
        int len)

Bulk set: set at least one and at most len longs starting at off in arr into this mutable, starting at index. Returns the actual number of values that have been set.

fill

void fill(int fromIndex,
          int toIndex,
          long val)

Fill the mutable from fromIndex (inclusive) to toIndex (exclusive) with val.

clear

void clear()

Sets all values to 0.

save

void save(DataOutput out)
          throws IOException

Save this mutable into out. Instantiating a reader from the generated data will return a reader with the same number of bits per value.

Throws:

IOException
