package Stat
Combine two stats into a new stat
Necessary method used by the StatIterator.
Necessary method used by the StatIterator. Indicates if the stat has any values or not
true if stat contains values
Compares the two stats for equivalence.
Compares the two stats for equivalence. We don't use standard 'equals' as it gets messy with mutable state and hash codes
other stat to compare
true if equals

Returns a representation of the Stat to be serialized
Returns a representation of the Stat to be serialized
This function should return a representation (view) of the Stat to be serialized as JSON. Instances of Map can be used to represent JSON dictionaries or Seq for JSON arrays. A collection.SortedMap such as collection.immutable.ListMap is recommended if key order should be deterministic. Other types may be used but could require the creation and registration of custom serializers dependent on the JSON framework being utilized (currently Gson).

Non type-safe add - if stats are not the same type, will throw an exception

Add another stat to this stat.
Add another stat to this stat. Avoids allocating another object.

Clears the stat to its original state when first initialized.
Clears the stat to its original state when first initialized. Necessary method used by the StatIterator.
Compute statistics based upon the given simple feature.
Compute statistics based upon the given simple feature. This method will be called for every SimpleFeature a query returns.

Returns a JSON representation of the Stat
Tries to remove the given simple feature from the compiled statistics.
Tries to remove the given simple feature from the compiled statistics. Note: may not be possible to un-observe a feature, in which case this method will have no effect.
