Method Detail

fillPages

protected final void fillPages()

newMutable

protected abstract PackedInts.Mutable newMutable(int valueCount,
                                                 int bitsPerValue)

size

public final long size()

The number of values.

get

public final long get(long index)

Description copied from class: LongValues

Get value at index.

Specified by:

get in class LongValues

set

public final void set(long index,
                      long value)

Set value at index.

baseRamBytesUsed

protected long baseRamBytesUsed()

ramBytesUsed

public long ramBytesUsed()

Description copied from interface: Accountable

Return the memory usage of this object in bytes. Negative values are illegal.

Specified by:

ramBytesUsed in interface Accountable

newUnfilledCopy

protected abstract T newUnfilledCopy(long newSize)

resize

public final T resize(long newSize)

Create a new copy of size newSize based on the content of this buffer. This method is much more efficient than creating a new instance and copying values one by one.

grow

public final T grow(long minSize)

Similar to ArrayUtil.grow(long[], int).

grow

public final T grow()

Similar to ArrayUtil.grow(long[]).

toString

public final String toString()

Overrides:

toString in class Object
