Class NioBufferIterator

java.lang.Object
libcore.io.BufferIterator

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 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.
