Class IIOByteBuffer

Contents

  • public class IIOByteBuffer
extends Object
    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.

    • Constructor Detail

      • IIOByteBuffer

        public IIOByteBuffer(byte[] data,
             int offset,
             int length)
        Constructs an IIOByteBuffer that references a given byte array, offset, and length.
        Parameters:
        data - a byte array.
        offset - an int offset within the array.
        length - an int specifying the length of the data of interest within byte array, in bytes.

    • Method Detail

      • getData

        public byte[] getData()
        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.
        See Also:
        getOffset(), getLength(), setData(byte[])

      • setData

        public void setData(byte[] data)
        Updates the array reference that will be returned by subsequent calls to the getData method.
        Parameters:
        data - a byte array reference containing the new data value.
        See Also:
        getData()

      • getOffset

        public int getOffset()
        Returns the offset within the byte array returned by getData at which the data of interest start.
        Returns:
        an int offset.
        See Also:
        getData(), getLength(), setOffset(int)

      • setOffset

        public void setOffset(int offset)
        Updates the value that will be returned by subsequent calls to the getOffset method.
        Parameters:
        offset - an int containing the new offset value.
        See Also:
        getOffset()

      • getLength

        public int getLength()
        Returns the length of the data of interest within the byte array returned by getData.
        Returns:
        an int length.
        See Also:
        getData(), getOffset(), setLength(int)

      • setLength

        public void setLength(int length)
        Updates the value that will be returned by subsequent calls to the getLength method.
        Parameters:
        length - an int containing the new length value.
        See Also:
        getLength()
