Method Detail
-
reset
public void reset(byte[] bytes)
-
rewind
public void rewind()
-
getPosition
public int getPosition()
-
setPosition
public void setPosition(int pos)
-
reset
public void reset(byte[] bytes, int offset, int len)
-
length
public int length()
-
eof
public boolean eof()
-
skipBytes
public void skipBytes(long count)
Description copied from class:DataInputSkip overnumBytesbytes. This method may skip bytes in whatever way is most optimal, and may not have the same behavior as reading the skipped bytes. In general, negativenumBytesare not supported.
-
readShort
public short readShort()
Description copied from class:DataInputReads two bytes and returns a short (LE byte order).- Overrides:
readShortin classDataInput- See Also:
DataOutput.writeShort(short),BitUtil.VH_LE_SHORT
-
readInt
public int readInt()
Description copied from class:DataInputReads four bytes and returns an int (LE byte order).- Overrides:
readIntin classDataInput- See Also:
DataOutput.writeInt(int),BitUtil.VH_LE_INT
-
readLong
public long readLong()
Description copied from class:DataInputReads eight bytes and returns a long (LE byte order).- Overrides:
readLongin classDataInput- See Also:
DataOutput.writeLong(long),BitUtil.VH_LE_LONG
-
readVInt
public int readVInt()
Description copied from class:DataInputReads an int stored in variable-length format. Reads between one and five bytes. Smaller values take fewer bytes. Negative numbers are supported, but should be avoided.The format is described further in
DataOutput.writeVInt(int).- Overrides:
readVIntin classDataInput- See Also:
DataOutput.writeVInt(int)
-
readVLong
public long readVLong()
Description copied from class:DataInputReads a long stored in variable-length format. Reads between one and nine bytes. Smaller values take fewer bytes. Negative numbers are not supported.The format is described further in
DataOutput.writeVInt(int).- Overrides:
readVLongin classDataInput- See Also:
DataOutput.writeVLong(long)
-
readByte
public byte readByte()
Description copied from class:DataInputReads and returns a single byte.- Specified by:
readBytein classDataInput- See Also:
DataOutput.writeByte(byte)
-
readBytes
public void readBytes(byte[] b, int offset, int len)Description copied from class:DataInputReads a specified number of bytes into an array at the specified offset.- Specified by:
readBytesin classDataInput- Parameters:
b- the array to read bytes intooffset- the offset in the array to start storing byteslen- the number of bytes to read- See Also:
DataOutput.writeBytes(byte[],int)
