let scb = new scb_wrapper.SCB("sv")

The SCB class can also be instaniated with a variable amount of pre determined steps down the path.

let scb = new scb_wrapper.SCB("sv", "BE", "BE0001", "BE0001G", "BE0001T06AR")

getInfo() : Can be used to get the inforamtion of the current path.

scb.getInfo().then(res => {
    console.log(res)
})

moveDown(...path) : Can be used to move down the path to a specific node.

scb.moveDown(path)

Example:

scb.moveDown("BE")
scb.moveDown("BE0001")
//or do it directly
scb.moveDown("BE", "BE0001")

moveUp(steps) : Can be used to move up the path a speficic amount of steps.

scb.moveUp(steps)

Example:

scb.moveUp(1) or scb.moveUp() //to move up one step
scb.moveUp(3) //to move up three steps

moveToTop() : Can be used to move to the top node.

scb.moveToTop()

getCurrentPath() : Can be used to get the current path.

scb.getCurrentPath()

isLeafNode(response) : Can used to check if the current node is a leaf/end node. Will return true if the current node is a leaf node false otherwise.

scb.getInfo().then(resp => {
    console.log(scb.isLeafNode(res))
});

getVariables() : Can be used to get all the possible variables that can be used for a query request. Can only be used at leaf node.

scb.getVariables().then(res => {
    console.log(res)
})

getVariablesCodes() : Can be used to get all the variables code/keys for a query request. Can only be used at leaf node.

scb.getVariablesCodes().then(res => {
    console.log(res)
})

getVariableValuesFromText(text) : Can be used to get a all the variables for a specific code/key. Can only be used at leaf node.

scb.getVariableValuesFromText(variableCode).then(res => {

})

Example:

let  scb = new  functions.SCB("sv", "BE", "BE0001", "BE0001G", "BE0001T06AR")

scb.getVariableValuesFromText("tilltalsnamn").then(res => {
    console.log(res)
})//Will return all the available values for the key "tilltalsnamn"

let parameters = [
{"tilltalsnamn" : ["Niklas"]},
{"tabellinnehåll" : ["Antal bärare"]},

})

{"tabellinnehåll" : ["Antal bärare"]},

]

scb.setQuery(parameters).then(response  => {
