Index Modes
List of ndarray index modes.
Usage
var modes = require( '@stdlib/ndarray/index-modes' );
modes()
Returns a list of ndarray index modes.
var out = modes();
// returns [ 'throw', 'clamp', 'wrap' ]
The output array
contains the following modes:
throw
: specifies that a function should throw an error when an index is outside a restricted interval.wrap
: specifies that a function should wrap around an index using modulo arithmetic.clamp
: specifies that a function should set an index less than0
to0
(minimum index) and set an index greater than a maximum index value to the maximum possible index.
Examples
var indexOf = require( '@stdlib/utils/index-of' );
var modes = require( '@stdlib/ndarray/index-modes' );
var MODES = modes();
var bool;
function isMode( str ) {
if ( indexOf( MODES, str ) === -1 ) {
return false;
}
return true;
}
bool = isMode( 'throw' );
// returns true
bool = isMode( 'clamp' );
// returns true
bool = isMode( 'wrap' );
// returns true
bool = isMode( 'beep' );
// returns false
