Overview

Checking types

• isUndefined(value)
• isInvalid(value)
• isArray(value)
• isAACompatible(value)
• isString(value)
• isBoolean(value)
• isFunction(value)
• isInteger(value)
• isNumber(value)
• isFloat(value)
• isPoint(value)

Equality

• isPointEqual(value, otherValue)

Debugging

• dv(view) - for debugging. Returns a view's type and id

Function invocation

• callAAFunc(target, funcName, p1 = "#M_NONE#", p2 = "#M_NONE#", p3 = "#M_NONE#") - invokes the aa function funcName on target
• apply(func, args = [], target = invalid), func) - similar to js apply

Object utilities

• getPath(content, field, default = invalid, disableIndexing = false) - safely gets the value from an object, at the given path
• setPath(content, field, value = invalid) - safely sets a value on object, at the given path
• removeDuplicateKeys(aa = invalid, otherAA = invalid)
• setOrAddNodeField(node, field, value = invalid)
• setNodeAAValue(node, field, key, value = invalid)
• setNodeArrayValue(node, field, index, value = invalid)
• setOrAddNodeFields(node, fields)
• getChildAtDepth(node, depth)
• createSGNode(nodeType, parent = invalid, id = invalid, args = invalid, isCallingInitialize = true) - create an roSGNode subclass of nodeType. Will automatically call initialize, and set the args
• createNode(nodeType) - create any type of roku node
• getFunctionName(value)

Conversions

• strToBool(s)
• strToInt(s)
• strToLong(value)

General

• getIndexOfItem(parent, item)
• toggleObserver(target, field, callbackName = invalid)
• clamp(number, low, high, wrap = false)

Access utils

• getMField(fieldName) - get a field on the top node's m - useful for vm classes
• getGlobal() - get global on the top node's m - useful for vm classes
• getTop() - get top on this node - useful for vm classes
• getScene() - get scene on this node - useful for vm classes
