- - ### Constructor Detail

    - #### XMPArray

          public XMPArray(XMPArrayType type)

      Main constructor
      Parameters:
        `type` - the intended type of array

  - ### Method Detail

    - #### getType

          public XMPArrayType getType()

      Returns:
        the type of array

    - #### getValue

          public java.lang.Object getValue(int idx)

      Returns the value at a given position.
      Parameters:
        `idx` - the index of the requested value
      Returns:
        the value at the given position

    - #### getStructure

          public XMPStructure getStructure(int idx)

      Returns the structure at a given position. If the value is not a structure a ClassCastException is thrown.
      Parameters:
        `idx` - the index of the requested value
      Returns:
        the structure at the given position

    - #### getSimpleValue

          public java.lang.Object getSimpleValue()

      Returns a normal Java object representing the value if it is available.
      Specified by:
        `getSimpleValue` in class `XMPComplexValue`
      Returns:
        a simple object value or null if no such value can be returned (for example, because the value is an array and has multiple entries.

    - #### getLangValue

          public java.lang.String getLangValue(java.lang.String lang)

      Returns a language-dependent values (available for alternative arrays).
      Parameters:
        `lang` - the language ("x-default" for the default value)
      Returns:
        the requested value

    - #### removeLangValue

          public java.lang.String removeLangValue(java.lang.String lang)

      Removes a language-dependent value.
      Parameters:
        `lang` - the language ("x-default" for the default value)
      Returns:
        the removed value (or null if no value was set)

    - #### add

          public void add(java.lang.Object value)

      Adds a new value to the array

        `value` - the value

    - #### remove

          public boolean remove(java.lang.String value)

      Removes a value from the array. If the value doesn't exist, nothing happens.
      Parameters:
        `value` - the value to be removed
      Returns:
        true if the value was removed, false if it wasn't found

    - #### add

          public void add(java.lang.String value,
                          java.lang.String lang)

      Adds a language-dependent value to the array. Make sure not to add the same language twice.
      Parameters:
        `value` - the value
        `lang` - the language ("x-default" for the default value)

    - #### getSize

          public int getSize()

      Returns the current number of values in the array.
      Returns:
        the current number of values in the array

    - #### isEmpty

          public boolean isEmpty()

      Indicates whether the array is empty or not.
      Returns:
        true if the array is empty

    - #### toObjectArray

          public java.lang.Object[] toObjectArray()

      Converts the array to an object array.
      Returns:
        an object array of all values in the array

    - #### toSAX
