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 numBytes) throws java.io.IOException
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.
-
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
-
setPosDelta
