Method Detail
-
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:
DataOutput.writeBytes(byte[],int)
-
skipBytes
public void skipBytes(long count)
Description copied from class:DataInput
Skip overnumBytes
bytes. The contract on this method is that it should have the same behavior as reading the same number of bytes into a buffer and discarding its content. Negative values ofnumBytes
are not supported.
-
getPosition
public long getPosition()
Description copied from class:FST.BytesReader
Get current read position.- Specified by:
getPosition
in classFST.BytesReader
-
setPosition
public void setPosition(long pos)
Description copied from class:FST.BytesReader
Set current read position.- Specified by:
setPosition
in classFST.BytesReader
-
reversed
public boolean reversed()
Description copied from class:FST.BytesReader
Returns true if this reader uses reversed bytes under-the-hood.- Specified by:
reversed
in classFST.BytesReader
