.haskey - macmcmeans/localDataStorage GitHub Wiki

localDataStorage.haskey( keyName )

This checks the store for the existence of keyName and returns true or false (query by name). The argument is case-sensitive.

EXAMPLE:

● localData.haskey( 'key2' )   -->   true

To determine if a certain value exists in the store, use hasval, and to check whether a specific data type exists, use hastype.
