Package com.codename1.call.spi

package com.codename1.call.spi

The seam between the portable com.codename1.call API and each platform's native call stack.

Application code never references anything here. CallBridge is implemented by the ports, obtained by the public packages through com.codename1.ui.Display#getCallBridge(), and the base implementation returns null -- which is the capability query, and the reason the public API degrades cleanly instead of throwing on a port that implements nothing.

The interface's own documentation carries the rules that make it implementable from Objective-C through ParparVM: primitives only, request ids for asynchrony, and the requirement that every operation answers exactly once.
