public final class InternalByteArray
extends Object

Wrapper object containing a TruffleString's internal byte array, along with a byte offset and length defining the region in use.

Since:

Method Detail

getArray

public byte[] getArray()

Get the internal byte array. Do not modify the array's contents!

Since:

getOffset

public int getOffset()

Get the string region's starting index.

Since:

22.1

getLength

public int getLength()

Get the string region's length.

Since:

getEnd

public int getEnd()

Get the string region's end (offset + length).

Since:

get

public byte get(int index)

Read the byte at getArray()[getOffset() + index] and return it as a byte, similar to TruffleString.ReadByteNode. Consider using TruffleString.ReadByteNode (and TruffleString.MaterializeNode before) instead if not needing the byte[] for other purposes, as that will avoid extra copying if the string is stored in native memory.
