=head1 NAME
File::RandomAccess - Random access reads of sequential file or scalar
=head1 SYNOPSIS
use File::RandomAccess;
$raf = new File::RandomAccess(\*FILE, $disableSeekTest);
$raf = new File::RandomAccess(\$data);
$err = $raf->Seek($pos);
$num = $raf->Read($buff, $bytes);
=head1 DESCRIPTION
Allows random access to sequential file by buffering the file if necessary.
Also allows access to data in memory to be accessed as if it were a file.
=head1 METHODS
=over 4
=item B<new>
Creates a new RandomAccess object given a file reference or
reference to data in memory.
# Read from open file or pipe
$raf = new File::RandomAccess(\*FILE);
# Read from data in memory
$raf = new File::RandomAccess(\$data);
=over 4
=item Inputs:
0) Reference to RandomAccess object or RandomAccess class name.
1) File reference or scalar reference.
2) Flag set if file is already random access (disables automatic SeekTest).
=item Returns:
Reference to RandomAccess object.
=back
=item B<SeekTest>
Performs test seek() on file to determine if buffering is necessary. If
the seek() fails, then the file is buffered to allow random access.
B<SeekTest>() is automatically called from B<new> unless specified.
$result = $raf->SeekTest();
=over 4
=item Inputs:
0) Reference to RandomAccess object.
=item Returns:
1 if seek test passed (ie. no buffering required).
=item Notes:
Must be called before any other i/o.
=back
=item B<Tell>
Get current position in file
$pos = $raf->Tell();
=over 4
=item Inputs:
0) Reference to RandomAccess object.
=item Returns:
Current position in file
=back
=item B<Seek>
Seek to specified position in file. When buffered, this doesn't quite
behave like seek() since it returns success even if you seek outside the
limits of the file.
$success = $raf->Seek($pos, 0);
=over 4
=item Inputs:
0) Reference to RandomAccess object.
1) Position.
2) Whence (0=from start, 1=from cur pos, 2=from end).
=item Returns:
1 on success, 0 otherwise
=back
=item B<Read>
Read data from the file.
$num = $raf->Read($buff, 1024);
=over 4
=item Inputs:
0) Reference to RandomAccess object.
1) Buffer.
2) Number of bytes to read.
=item Returns:
Number of bytes actually read.
=back
=item B<ReadLine>
Read a line from file (end of line is $/).
=over 4
=item Inputs:
0) Reference to RandomAccess object.
1) Buffer.
=item Returns:
Number of bytes read.
=back
=item B<Slurp>
Read whole file into buffer, without changing read pointer.
=over 4
=item Inputs:
0) Reference to RandomAccess object.
=item Returns:
Nothing.
=back
=item B<BinMode>
Set binary mode for file.
=over 4
=item Inputs:
0) Reference to RandomAccess object.
=item Returns:
Nothing.
=back
=item B<Close>
Close the file and free the buffer.
=over 4
=item Inputs:
0) Reference to RandomAccess object.
=item Returns:
Nothing.
=back
