javax.imageio.stream.IIOByteBuffer — clojure-interop/javax.imageio 1.0.5

A class representing a mutable reference to an array of bytes and an offset and length within that array. IIOByteBuffer is used by ImageInputStream to supply a sequence of bytes to the caller, possibly with fewer copies than using the conventional read methods that take a user-supplied byte array.

The byte array referenced by an IIOByteBuffer will generally be part of an internal data structure belonging to an ImageReader implementation; its contents should be considered read-only and must not be modified.

->iio-byte-buffer clj

(->iio-byte-buffer data offset length)

Constructor.

Constructs an IIOByteBuffer that references a given byte array, offset, and length.

data - a byte array. - byte[] offset - an int offset within the array. - int length - an int specifying the length of the data of interest within byte array, in bytes. - int

get-data clj

(get-data this)

Returns a reference to the byte array. The returned value should be treated as read-only, and only the portion specified by the values of getOffset and getLength should be used.

returns: a byte array reference. - byte[]

get-length clj

(get-length this)

Returns the length of the data of interest within the byte array returned by getData.

returns: an int length. - int

get-offset clj

(get-offset this)

Returns the offset within the byte array returned by getData at which the data of interest start.

returns: an int offset. - int

set-data clj

(set-data this data)

Updates the array reference that will be returned by subsequent calls to the getData method.

data - a byte array reference containing the new data value. - byte[]

set-length clj

(set-length this length)

Updates the value that will be returned by subsequent calls to the getLength method.

length - an int containing the new length value. - int

set-offset clj

(set-offset this offset)

Updates the value that will be returned by subsequent calls to the getOffset method.

offset - an int containing the new offset value. - int
