/**
* An Annotation object is used as a wrapper for a text attribute value if
* the attribute has annotation characteristics. These characteristics are:
* 
    *
  • 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. *
  • The attribute or its value usually do no longer apply if the underlying text is * changed. *
* * 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). * *

* 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. * * @see AttributedCharacterIterator * @since 1.2 */ public class Annotation { /** * Constructs an annotation record with the given value, which * may be null. * * @param value the value of the attribute */ public Annotation(Object value) { this.value = value; } /** * Returns the value of the attribute, which may be null. * * @return the value of the attribute */ public Object getValue() { return value; } /** * Returns the String representation of this Annotation. * * @return the {@code String} representation of this {@code Annotation} */ public String toString() { return getClass().getName() + "[value=" + value + "]"; } private Object value; };
