  • Constructor Details

    • MutablePropertySet

      public MutablePropertySet()

      Constructs a MutablePropertySet instance. Its primary task is to initialize the immutable field with their proper values. It also sets fields that might change to reasonable defaults.

    • MutablePropertySet

      public MutablePropertySet(PropertySet ps)

      Constructs a MutablePropertySet by doing a deep copy of an existing PropertySet. All nested elements, i.e. Sections and Property instances, will be their mutable counterparts in the new MutablePropertySet.

      Parameters:
      ps - The property set to copy
  • Method Details

    • setByteOrder

      public void setByteOrder(int byteOrder)

      Sets the "byteOrder" property.

      Parameters:
      byteOrder - the byteOrder value to set
    • setFormat

      public void setFormat(int format)

      Sets the "format" property.

      Parameters:
      format - the format value to set
    • setOSVersion

      public void setOSVersion(int osVersion)

      Sets the "osVersion" property.

      Parameters:
      osVersion - the osVersion value to set
    • setClassID

      public void setClassID(ClassID classID)

      Sets the property set stream's low-level "class ID" field.

      Parameters:
      classID - The property set stream's low-level "class ID" field.
      See Also:
    • clearSections

      public void clearSections()

      Removes all sections from this property set.

    • addSection

      public void addSection(Section section)

      Adds a section to this property set.

      Parameters:
      section - The Section to add. It will be appended after any sections that are already present in the property set and thus become the last section.
    • write

      public void write(OutputStream out) throws WritingNotSupportedException, IOException

      Writes the property set to an output stream.

      Parameters:
      out - the output stream to write the section to
      Throws:
      IOException - if an error when writing to the output stream occurs
      WritingNotSupportedException - if HPSF does not yet support writing a property's variant type.
    • toInputStream

      public loci.common.RandomAccessInputStream toInputStream() throws IOException, WritingNotSupportedException

      Returns the contents of this property set stream as an input stream. The latter can be used for example to write the property set into a POIFS document. The input stream represents a snapshot of the property set. If the latter is modified while the input stream is still being read, the modifications will not be reflected in the input stream but in the MutablePropertySet only.

      Returns:
      the contents of this property set stream
      Throws:
      WritingNotSupportedException - if HPSF does not yet support writing of a property's variant type.
      IOException - if an I/O exception occurs.
    • write

      public void write(DirectoryEntry dir, String name) throws WritingNotSupportedException, IOException

      Writes a property set to a document in a POI filesystem directory.

      Parameters:
      dir - The directory in the POI filesystem to write the document to.
      name - The document's name. If there is already a document with the same name in the directory the latter will be overwritten.
      Throws:
      WritingNotSupportedException
      IOException
