canStart method
This tool can run when the diagram allows linking, the model is modifiable, the left-button mouse drag has moved far enough away to not be a click, and when #findLinkablePort has returned a valid port or when #startObject is a valid port.
This method may be overridden, but we recommend that you call this base method. @return {boolean}
Implementation
_i2.bool canStart() => _i4.callMethod(
this,
'canStart',
[],
);
