Method Detail

get

public long get(int index)

Description copied from class: PackedInts.Reader

Get the long at the given index. Behavior is undefined for out-of-range indices.

Specified by:

get in class PackedInts.Reader

set

public void set(int index,
                long value)

Description copied from class: PackedInts.Mutable

Set the value at the given index in the array.

Specified by:

set in class PackedInts.Mutable

Parameters:

index - where the value should be positioned.

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

ramBytesUsed

public long ramBytesUsed()

Description copied from interface: Accountable

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

clear

public void clear()

Description copied from class: PackedInts.Mutable

Sets all values to 0.

Overrides:

clear in class PackedInts.Mutable

get

public int get(int index,
               long[] arr,
               int off,
               int len)

Description copied from class: PackedInts.Reader

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.

Overrides:

get in class PackedInts.Reader

set

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

Description copied from class: PackedInts.Mutable

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.

Overrides:

set in class PackedInts.Mutable

fill

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

Description copied from class: PackedInts.Mutable

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

Overrides:

fill in class PackedInts.Mutable
