来自eclipse项目的Boolean fun

Posted 2021-02-26

i love those ternary expressions, they really make things clear, don't they? found in org.eclipse.jface.action.Action

public void setEnabled(boolean enabled) {
	if (enabled != this.enabled) {
		Boolean oldVal = this.enabled ? Boolean.TRUE : Boolean.FALSE;
		Boolean newVal = enabled ? Boolean.TRUE : Boolean.FALSE;
		this.enabled = enabled;
		firePropertyChange(ENABLED, oldVal, newVal);
	}
}
