Class NioBufferIterator

java.lang.Object

libcore.io.BufferIterator

libcore.io.NioBufferIterator

public final class NioBufferIterator
extends BufferIterator

Iterates over big- or little-endian bytes on the native heap. See MemoryMappedFile.bigEndianIterator() and MemoryMappedFile.littleEndianIterator().

Method Summary

Modifier and Type	Method and Description
byte	readByte() Returns the byte at the current position, and advances the current position one byte.
void	readByteArray(byte[] dst, int dstOffset, int byteCount) Copies byteCount bytes from the current position into dst, starting at dstOffset, and advances the current position byteCount bytes.
int	readInt() Returns the 32-bit int at the current position, and advances the current position four bytes.
void	readIntArray(int[] dst, int dstOffset, int intCount) Copies intCount 32-bit ints from the current position into dst, starting at dstOffset, and advances the current position 4 * intCount bytes.
short	readShort() Returns the 16-bit short at the current position, and advances the current position two bytes.
void	seek(int offset) Seeks to the absolute position offset, measured in bytes from the start.
void	skip(int byteCount) Skips forwards or backwards byteCount bytes from the current position.
