Parameters:

s - The serialized hstore/map string.

Returns:

A new StringMapEntry containing the deserialized key and value.

Throws:

java.lang.IllegalArgumentException - if the provided string does not contain exactly one entry.

Parameters:

entry - The entry to convert into a StringMapEntry.

Returns:

A new StringMapEntry containing the key and value of the passed entry.
