array-kv-reduce clj

(array-kv-reduce ral read-from-cursor f init)

Efficiently reduces over index-value pairs in a ReadArrayList.

array-list-append-value! clj

(array-list-append-value! wal v)

Appends a value to a WriteArrayList. Converts the value to an appropriate XitDB representation using v->slot!.

array-list-assoc-value! clj

(array-list-assoc-value! wal i v)

Associates a value at index i in a WriteArrayList. Appends the value if the index equals the current count. Replaces the value at the specified index otherwise. Throws an IllegalArgumentException if the index is out of bounds.

array-list-empty! clj

(array-list-empty! wal)

Empties a WriteArrayList by replacing its contents with an empty array. Returns the modified WriteArrayList.

array-list-pop! clj

(array-list-pop! wal)

Removes the last element from a WriteArrayList. Throws IllegalStateException if the array is empty. Returns the array list with the last element removed.

array-seq clj

(array-seq ral read-from-cursor)

Creates a lazy sequence from a ReadArrayList. Uses the provided read-from-cursor function to convert cursors to values. Returns a lazy sequence of the array elements.

linked-array-list-append-value! clj

(linked-array-list-append-value! wlal v)

Appends a value to a WriteLinkedArrayList. Converts the value to an appropriate XitDB representation using v->slot!.

linked-array-list-insert-value! clj

(linked-array-list-insert-value! wlal pos v)

Inserts a value at position pos in a WriteLinkedArrayList. Converts the value to an appropriate XitDB representation using v->slot!.

linked-array-list-pop! clj

(linked-array-list-pop! wlal)

Removes the first element from a WriteLinkedArrayList. This is a stack-like operation (LIFO) for linked lists. Returns the modified WriteLinkedArrayList.

linked-array-seq clj

(linked-array-seq rlal read-from-cursor)

Creates a lazy sequence from a ReadLinkedArrayList. Uses the provided read-from-cursor function to convert cursors to values. Returns a lazy sequence of the linked array elements.

map-assoc-value! clj

(map-assoc-value! whm k v)

Associates a key-value pair in a WriteHashMap.

Args: whm - The WriteHashMap to modify k - The key to associate (converted to XitDB representation) v - The value to associate (converted to XitDB representation)

Returns the modified WriteHashMap.

Throws IllegalArgumentException if attempting to associate an internal key. Updates the internal count if fast counting is enabled.

map-contains-key? clj

(map-contains-key? whm key)

Checks if a WriteHashMap contains the specified key. Returns true if the key exists, false otherwise.

map-dissoc-key! clj

(map-dissoc-key! whm k)

Removes a key-value pair from a WriteHashMap. Throws IllegalArgumentException if attempting to remove an internal key. Updates the internal count if fast counting is enabled.

map-empty! clj

(map-empty! whm)

Empties a WriteHashMap by replacing its contents with an empty map. Returns the modified WriteHashMap.

map-item-count clj

(map-item-count rhm)

Returns the number of key/vals in the map.

map-item-count-iterated clj

(map-item-count-iterated rhm)

Returns the number of keys in the map by iterating. The count includes internal keys if any.

map-kv-reduce clj

(map-kv-reduce rhm read-from-cursor f init)

Efficiently reduces over key-value pairs in a ReadHashMap, skipping hidden keys.

map-read-cursor clj

(map-read-cursor rhm key)

Gets a read cursor for the specified key in a ReadHashMap. Returns the cursor if the key exists, nil otherwise.

map-seq clj

(map-seq rhm read-from-cursor)

Return a lazy seq of key-value MapEntry pairs.

map-write-cursor clj

(map-write-cursor whm key)

Gets a write cursor for the specified key in a WriteHashMap. Creates the key if it doesn't exist.

set-assoc-value! clj

(set-assoc-value! whs v)

Adds a value to a set.

set-contains? clj

(set-contains? rhs v)

Returns true if v is in the set.

set-disj-value! clj

(set-disj-value! whs v)

Removes a value from a set

set-empty! clj

(set-empty! whs)

Replaces the whs value with an empty set.

set-item-count clj

(set-item-count rhs)

Returns the number of values in the set.

set-seq clj

(set-seq rhm read-from-cursor)

Return a lazy seq values from the set.
