IsObjectValid(handle)

Description

The IsObjectValid function returns a boolean true or nil depending on whether the supplied argument is a valid object.

Arguments

• Handle:
  The argument should be the handle to a possible object.

Return

• Boolean or nil:
  The returned value is a boolean True if the handle is a valid object or it returns nil if it is not a valid object.

Example

This example below examines if "Root()" is a valid object and prints meaningful feedback:

return function()
    --Create a variable with the possible object
    local myObject = Root()
    --Check if it is an object
    local myReturn = IsObjectValid(myObject)
    --Print the result
    if myReturn == nil then
        ErrPrintf("It is not a valid object")
    else
        Printf("It is an object")
    end
end
