Parameters:

compositeKey -

Returns:

Composite Key

validateSimpleKeys

public static void validateSimpleKeys(java.lang.String... keys)

To ensure that simple keys do not go into composite key namespace, we validate simple key to check whether the key starts with 0x00 (which is the namespace for compositeKey). This helps in avoiding simple/composite key collisions.

Parameters:

keys - the list of simple keys
