Public Methods

Method	Description
PersistentArrayMap ( object init ) : System	Initializes a PersistentArrayMap to use the supplied key/value array. The array is used directly. Do not modify externally or immutability is sacrificed.
asTransient ( ) : ITransientCollection
assoc ( object key, object val ) : IPersistentMap	Add a new key/value pair. Overwrites an exising value for the key, if present.
assocEx ( object key, object val ) : IPersistentMap	Add a new key/value pair. Throws an exception if key has a value already.
containsKey ( object key ) : bool	Test if the map contains a key.
count ( ) : int	Gets the number of items in the collection.
empty ( ) : IPersistentCollection	Gets an empty collection of the same type.
entryAt ( object key ) : IMapEntry	Returns the key/value pair for this key.
meta ( ) : IPersistentMap
seq ( ) : ISeq	Gets an ISeq to allow first/rest iteration through the collection.
valAt ( object key ) : object	Gets the value associated with a key.
valAt ( object key, object notFound ) : object	Gets the value associated with a key.
withMeta ( IPersistentMap meta ) : IObj	Create a copy with new metadata.
without ( object key ) : IPersistentMap	Remove a key entry.

Protected Methods

Method	Description
PersistentArrayMap ( ) : System	Create an empty PersistentArrayMap.
PersistentArrayMap ( IPersistentMap meta, object init ) : System	Initializes a PersistentArrayMap to use the supplied key/value array and metadata. The array is used directly. Do not modify externally or immutability is sacrificed.

Private Methods

Method	Description
EqualKey ( object k1, object k2 ) : bool	Compare two keys for equality. Handles nulls properly.
IndexOfKey ( object key ) : int	Gets the index of the key in the array.
create ( IDictionary other ) : IPersistentMap
create ( ) : PersistentArrayMap
createHT ( object init ) : IPersistentMap	Create an IPersistentMap to hold the data when an operation causes the threshhold size to be exceeded.
createWithCheck ( Object init ) : PersistentArrayMap

Method Details

meta	IPersistentMap	The metadata to attach.
init	object	An array with alternating keys and values.
return	System

PersistentArrayMap() public method
