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

converts an nio ByteBuffer to another type

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

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

utility for getting arrays from buffers (def -arr- (double-array 2))

(buffer-get (double-buffer 1 2) -arr-) (seq -arr-) => 1.0 2.0

returns the corresponding type associated with the instance

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

utility for putting arrays into buffers

(buffer-put (double-buffer 2) (double-array 1 2))

reads primitive array from buffer

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

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

returns the corresponding type associated with the class

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

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

helper function for std.lib.bin.buffer/buffer-type

writes primitive array to a buffer

(def ^java.nio.ByteBuffer -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

converts keyword to ByteOrder

(byte-order :little) => java.nio.ByteOrder/LITTLE_ENDIAN

creates functions for buffer types

(macroexpand-1 ’(create-buffer-functions (:byte)))

creates records for buffer types

(macroexpand-1 ’(create-buffer-records (Byte identity)))
