-
rewind
public void rewind()
-
getPosition
public int getPosition()
-
setPosition
public void setPosition(int pos)
-
reset
public void reset(byte[] bytes, int offset, int len)

skipBytes
public void skipBytes(long count)
Description copied from class:DataInput
Skip overnumBytes
bytes. 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, negativenumBytes
are not supported.
-
readShort
public short readShort()
Description copied from class:DataInput
Reads two bytes and returns a short (LE byte order).- Overrides:
readShort
in classDataInput
- See Also:
DataOutput.writeShort(short)
,BitUtil.VH_LE_SHORT
-
readInt
public int readInt()
Description copied from class:DataInput
Reads four bytes and returns an int (LE byte order).- Overrides:
readInt
in classDataInput
- See Also:
DataOutput.writeInt(int)
,BitUtil.VH_LE_INT
-
readLong
public long readLong()
Description copied from class:DataInput
Reads eight bytes and returns a long (LE byte order).- Overrides:
readLong
in classDataInput
- See Also:
DataOutput.writeLong(long)
,BitUtil.VH_LE_LONG
-
readVInt
public int readVInt()
Description copied from class:DataInput
Reads 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:
readVInt
in classDataInput
- See Also:
DataOutput.writeVInt(int)
-
readVLong
public long readVLong()
Description copied from class:DataInput
Reads 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:
readVLong
in classDataInput
- See Also:
DataOutput.writeVLong(long)
-
readByte
public byte readByte()
Description copied from class:DataInput
Reads and returns a single byte.- Specified by:
readByte
in classDataInput
- See Also:
DataOutput.writeByte(byte)
-
readBytes
public void readBytes(byte[] b, int offset, int len)
Description copied from class:DataInput
Reads a specified number of bytes into an array at the specified offset.- Specified by:
readBytes
in 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:
