    • OtherFloatAttributeMultipleFilesOnDisk

      public OtherFloatAttributeMultipleFilesOnDisk(AttributeTag t, boolean bigEndian)

      Construct an (empty) attribute.

      Any file set later will be expected to be little endian.
      Parameters:
      t - the tag of the attribute
      bigEndian - big endian, false if little endian

    • OtherFloatAttributeMultipleFilesOnDisk

      public OtherFloatAttributeMultipleFilesOnDisk(AttributeTag t, File[] files, long[] byteOffsets, long[] lengths, boolean bigEndian) throws IOException, DicomException

      Read an attribute from a set of files.

      Parameters:
      t - the tag of the attribute
      files - the input files
      byteOffsets - the byte offsets in the files of the start of the data, one entry for each file, or null if 0 for all files
      lengths - the lengths in the files from the the start of the data, one entry for each file, or null if the remaining file length after the byteOffset, if any
      Throws:
      IOException
      DicomException

    • OtherFloatAttributeMultipleFilesOnDisk

      public OtherFloatAttributeMultipleFilesOnDisk(AttributeTag t, String[] fileNames, long[] byteOffsets, long[] lengths, boolean bigEndian) throws IOException, DicomException

  • Method Details

    • getFiles

      public File[] getFiles()
      Returns:
      the files containing the data

    • getByteOffsets

    • getPaddedVL

      public long getPaddedVL()
      Description copied from class: Attribute

      Get the value length of this attribute, accounting for the need for even-length padding.

      Overrides:
      getPaddedVL in class Attribute
      Returns:
      the value length (padded to an even length)

    • write

      public void write(DicomOutputStream o) throws DicomException, IOException
      Description copied from class: Attribute

      Write the entire attribute (including values) to the output stream.

      Specified by:
      write in class Attribute
      Parameters:
      o -
      Throws:
      IOException
      DicomException

    • toString

      public String toString(DicomDictionary dictionary)
      Description copied from class: Attribute

      Dump the contents of the attribute as a human-readable string.

      No new line is appended.

      The result is of the form:

       (0xgggg,0xeeee) Name VR=<XX> VL=<0xnnnn> <...>

      For example:

      dictionary - the dictionary to use to look up the name
      Returns:
      a single String value

    • removeValues

      public void removeValues()
      Description copied from class: Attribute
