Reads eight input bytes and returns a long value.

[Android.Runtime.Register("readLong", "()J", "GetReadLongHandler:Java.IO.IDataInputInvoker, Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null")]
public long ReadLong ();

[<Android.Runtime.Register("readLong", "()J", "GetReadLongHandler:Java.IO.IDataInputInvoker, Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null")>]
abstract member ReadLong : unit -> int64

Returns

Int64

the long value read.

Attributes: RegisterAttribute

Exceptions

EOFException

if the end of the input is reached before the read request can be satisfied.

IOException

if an I/O error occurs while reading.

Remarks

Reads eight input bytes and returns a long value. Let a-h be the first through eighth bytes read. The value returned is:

{@code
            (((long)(a & 0xff) << 56) |
             ((long)(b & 0xff) << 48) |
             ((long)(c & 0xff) << 40) |
             ((long)(d & 0xff) << 32) |
             ((long)(e & 0xff) << 24) |
             ((long)(f & 0xff) << 16) |
             ((long)(g & 0xff) <<  8) |
             ((long)(h & 0xff)))
            }

This method is suitable for reading bytes written by the writeLong method of interface DataOutput.
