Class GrowingByteArrayOutput

java.lang.Object

com.datadoghq.sketch.ddsketch.encoding.GrowingByteArrayOutput

All Implemented Interfaces:

Output

public final class GrowingByteArrayOutput
extends java.lang.Object
implements Output

An implementation of Output that is backed by an array of bytes, whose capacity is grown as necessary.

Method Summary

Modifier and Type	Method and Description
byte[]	backingArray()
void	clear() Discard the data that has been written to the backing array but avoid deallocating memory.
int	numWrittenBytes()
byte[]	trimmedCopy()
static GrowingByteArrayOutput	withDefaultInitialCapacity()
static GrowingByteArrayOutput	withInitialCapacity(int initialCapacity)
void	writeByte(byte value)

Method Detail

withInitialCapacity

public static GrowingByteArrayOutput withInitialCapacity(int initialCapacity)

withDefaultInitialCapacity

public static GrowingByteArrayOutput withDefaultInitialCapacity()

writeByte

public final void writeByte(byte value)

Specified by:

writeByte in interface Output

writeLongLE

public final void writeLongLE(long value)

Specified by:

writeLongLE in interface Output

clear

public final void clear()

Discard the data that has been written to the backing array but avoid deallocating memory.

backingArray

public final byte[] backingArray()

Returns:

the array that contains the written data, and possibly some additional trailing bytes; its numWrittenBytes() bytes match what trimmedCopy() would return

numWrittenBytes

public final int numWrittenBytes()

Returns:

the number of bytes that have been written to the backing array

trimmedCopy

public final byte[] trimmedCopy()

Returns:

an array that is distinct from the backing array that contains the written data (its size is numWrittenBytes())
