/**
|
|
* An Annotation object is used as a wrapper for a text attribute value if the
|
|
* attribute has annotation characteristics. These characteristics are:
|
|
* <ul>
|
|
* <li>The text range that the attribute is applied to is critical to the
|
|
* semantics of the range. That means, the attribute cannot be applied to
|
|
* subranges of the text range that it applies to, and, if two adjacent text
|
|
* ranges have the same value for this attribute, the attribute still cannot be
|
|
* applied to the combined range as a whole with this value.
|
|
* <li>The attribute or its value usually do no longer apply if the underlying
|
|
* text is changed.
|
|
* </ul>
|
|
*
|
|
* An example is grammatical information attached to a sentence: For the
|
|
* previous sentence, you can say that "an example" is the subject, but you
|
|
* cannot say the same about "an", "example", or "exam". When the text is
|
|
* changed, the grammatical information typically becomes invalid. Another
|
|
* example is Japanese reading information (yomi).
|
|
*
|
|
* <p>
|
|
* Wrapping the attribute value into an Annotation object guarantees that
|
|
* adjacent text runs don't get merged even if the attribute values are equal,
|
|
* and indicates to text containers that the attribute should be discarded if
|
|
* the underlying text is modified.
