buffer clj

(buffer len-or-elems)

(buffer
  len-or-elems
  {:keys [type direct endian convert wrap]
   :or
     {type :byte direct false endian +endian-native+ convert true wrap false}})

either creates or wraps a byte buffer of a given type

(buffer 10) => java.nio.ByteBuffer

(buffer 10 {:type :float :convert false}) => java.nio.ByteBuffer

(buffer 10 {:type :float :direct true}) => java.nio.FloatBuffer

buffer-convert clj

(buffer-convert buff type)

converts an nio ByteBuffer to another type

(buffer-convert (java.nio.ByteBuffer/allocate 8) :double) => java.nio.DoubleBuffer

buffer-create clj

(buffer-create type elems length direct endian convert)

creates a byte buffer

(buffer-create :double (double-array [1 2 3 4]) 4 true :little true) => java.nio.DoubleBuffer

(buffer-create :double (double-array [1 2 3 4]) 4 false :big false) => java.nio.ByteBuffer

buffer-primitive clj

(buffer-primitive buff)

(buffer-primitive buff tag)

returns the corresponding type associated with the instance

(buffer-primitive (double-buffer 0) :class) => Double/TYPE

buffer-read clj

(buffer-read buff)

(buffer-read buff arr)

reads primitive array from buffer

(def -buf- (buffer 4)) (def -out- (int-array 1))

(do (.put -buf- 3 (byte 1)) (buffer-read -buf- -out-) (first -out-)) => 1

buffer-type clj

(buffer-type cls)

(buffer-type cls tag)

returns the corresponding type associated with the class

(buffer-type java.nio.FloatBuffer :type) => :float

(buffer-type java.nio.FloatBuffer :array-fn) => float-array

buffer-type-raw clj

(buffer-type-raw cls)

(buffer-type-raw cls tag)

helper function for hara.io.binary.buffer/buffer-type

buffer-write clj

(buffer-write buff arr)

writes primitive array to a buffer

(def -buf- (buffer 16)) (buffer-write -buf- (int-array [1 2 3 4]))

[(.get -buf- 3) (.get -buf- 7) (.get -buf- 11) (.get -buf- 15)] => [1 2 3 4]

byte-buffer clj

(byte-buffer len-or-elems)

(byte-buffer len-or-elems {:keys [type direct endian convert] :as opts})

byte-order clj

(byte-order obj)
