Store Functions

Miscellaneous Store Functions

store:HasSoup(soupName)

This method returns true if store contains a soup named soupName. It returns nil otherwise. Here are two examples, one returning a soup, the other not:

internal := GetStores()[0];
Print(internal:HasSoup("Names"))
TRUE
Print(internal:HasSoup("Dinglehopper"))
NIL
store:IsValid()

This method returns true if store is valid, and nil otherwise. A store is invalid if it has been removed. Here is an example:

external:= GetStores()[1];
Print(external:IsValid())
TRUE
Now, remove the card from the Newton:

Print(external:IsValid())
NIL
