RedisTemplate Common Collection Instructions - boundListOps (8)

     The basic configuration has been introduced in the previous " RedisTemplate Common Collection Usage Instructions (1) ", now we directly introduce the use of the boundListOps() method:

       First define a BoundListOperations

//Define the binding key
BoundListOperations boundListOperations = redisTemplate.boundListOps("lk");

 1.leftPush(V value)和rightPush(V value)

     Add value to bind key

//Add the value to the bound key
boundListOperations.leftPush("h");
boundListOperations.leftPush("i");
boundListOperations.rightPush("a");
boundListOperations.rightPush("b");

 2.range(long start, long end)

     Get the interval value given in the bound key

//Get the value in the bound key
boundListOperations.range(0,-1).forEach(v -> System.out.println("Get the value in the bound key" + v));

3.index(long index)

    Get the value at a given location

//Get the value of a specific location
System.out.println("Get the value of a specific position: " + boundListOperations.index(0));

 4.leftPop()

    Pop the value on the left

// pop the left value
System.out.println("Pop left value:" + boundListOperations.leftPop());

5.rightPop()

    Pop the value on the right

// pop the value on the right
System.out.println("Pop right value:" + boundListOperations.rightPop());

6.leftPush(V pivot, V value)

    Adds values ​​to the left of the occurrence of the first value specified

//Add the value to the left of the first value specified
boundListOperations.leftPush("i","w");
boundListOperations.range(0,-1).forEach(v -> System.out.println("Add value to the left of the first value specified: " + v));

7.rightPush(V pivot, V value)

    Adds values ​​to the right of the occurrence of the first value specified

//Add the value to the right of the first value specified
boundListOperations.rightPush("i","x");
boundListOperations.range(0,-1).forEach(v -> System.out.println("Add value to the left of the first value specified: " + v));

8.leftPop(long timeout, TimeUnit unit)

    Pop the value on the left after the specified time

// pop up the left value after the specified time
boundListOperations.leftPop(1, TimeUnit.SECONDS);

9.rightPop(long timeout, TimeUnit unit)

     Pops the value on the right after the specified time

// pop up the value on the right after the specified time
boundListOperations.rightPop(1, TimeUnit.SECONDS);

 10.leftPushAll(V... values)

     Bulk add values ​​on the left

// add values ​​in batches on the left
boundListOperations.leftPushAll("y","g");
boundListOperations.range(0,-1).forEach(v -> System.out.println("Add values ​​in batches on the left: " + v));

11.rightPushAll(V... values)

    Bulk add values ​​on the right

//add values ​​in batches on the right
boundListOperations.rightPushAll("b","r");
boundListOperations.range(0,-1).forEach(v -> System.out.println("Add values ​​in batches on the right: " + v));

12.leftPushIfPresent(V value)

      Add non-existing value to the left

//Add non-existing value to the left
boundListOperations.leftPushIfPresent("k");
boundListOperations.leftPushIfPresent(";");
boundListOperations.range(0,-1).forEach(v -> System.out.println("Add non-existent value to the left: " + v));

 13.rightPushIfPresent(V value)

     Add non-existing value to the right

//Add non-existing value to the right
boundListOperations.rightPushIfPresent("k");
boundListOperations.rightPushIfPresent(";");
System.out.println("Add non-existent value to the right: " + boundListOperations.range(0,-1).toString());

14.remove(long count, Object value)

    remove the specified number of values

// remove the number of specified values
long removeCount = boundListOperations.remove(2,"i");
System.out.println("Remove the number of specified values:" + removeCount);
System.out.println("Remaining value after removing the specified number of values: " + boundListOperations.range(0,-1).toString());

15.set(long index, V value)

    add value at specified location

// set the value at the specified location
boundListOperations.set(0,"j");
System.out.println("Set the value at the specified position: " + boundListOperations.range(0,-1).toString());

16.trim(long start, long end)

    Truncate the value of the original interval to the new value

//Intercept the value of the specified interval position
boundListOperations.trim(1,3);
System.out.println("Intercept the value of the specified range position: " + boundListOperations.range(0,-1).toString());
