Overrides:
readVInt in class DataInput
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.

Overrides:
readVLong in class DataInput

readByte

public byte readByte()
Description copied from class: DataInput
Reads and returns a single byte.

Specified by:
readByte in class DataInput
See Also:
DataOutput.writeByte(byte)

readBytes

public void readBytes(byte[] b,
                      int offset,

Description copied from class: DataInput
Reads a specified number of bytes into an array at the specified offset.

Specified by:
readBytes in class DataInput
Parameters:
b - the array to read bytes into
offset - the offset in the array to start storing bytes
len - the number of bytes to read
