By default, the scope is public, the value can be accessed from anywhere.
package com.example {
class FooClass {
val x = "foo"
}
}
package an.other.package {
class BarClass {
val foo = new com.example.FooClass
foo.x // <- Accessing a public value from anothe...
When the scope is private, it can only be accessed from the current class or other instances of the current class.
package com.example {
class FooClass {
private val x = "foo"
def aFoo(otherFoo: FooClass) {
otherFoo.x // <- Accessing from another instance of the sam...
You can specify a package where the private value can be accessed.
package com.example {
class FooClass {
private val x = "foo"
private[example] val y = "bar"
}
class BarClass {
val f = new FooClass
f.x // <- Will not compile
f.y // <- Wil...
The most restrictive scope is "object-private" scope, which only allows that value to be accessed from the same instance of the object.
class FooClass {
private[this] val x = "foo"
def aFoo(otherFoo: FooClass) = {
otherFoo.x // <- This will not compile, accessing x...
The protected scope allows the value to be accessed from any subclasses of the current class.
class FooClass {
protected val x = "foo"
}
class BarClass extends FooClass {
val y = x // It is a subclass instance, will compile
}
class ClassB {
val f = new FooClass
f.x // <...
The package protected scope allows the value to be accessed only from any subclass in a specific package.
package com.example {
class FooClass {
protected[example] val x = "foo"
}
class ClassB extends FooClass {
val y = x // It's in the protected scope, will compile

You may also extend nested selectors. The below Less
.otherChild{
color: blue;
}
.otherParent{
color: red;
.otherChild{
font-size: 12px;
color: green;
}
}
.parent{
.nestedParagraph{
&:extend(.otherParent .otherChild);
}
}
Will compile to
.otherChild...
You can establish a transaction by calling the pipeline method on the StrictRedis. Redis commands executed against the transaction are performed in a single block.
# defaults to transaction=True
tx = r.pipeline()
tx.hincrbyfloat(debit_account_key, 'balance', -amount)
tx.hincrbyfloat(credit_acc...
In this example the microcontroller echos back the received bytes to the sender using UART RX interrupt.
#include "stm32f4xx.h"
UART_HandleTypeDef huart2;
/* Single byte to store input */
uint8_t byte;
void SystemClock_Config(void);
/* UART2 Interrupt Service Routine */
