Interface Utf8Entry
- All Superinterfaces:
- AnnotationConstantValueEntry,- CharSequence,- PoolEntry
CONSTANT_UTF8_info constant, representing strings, in the
 constant pool of a class file.  This describes strings in the
 Modified UTF-8 format.
 
 The use of a Utf8Entry is represented by a String.
 Conversions are through ConstantPoolBuilder.utf8Entry(String) and
 stringValue().
 
 Some uses of Utf8Entry represent field or method descriptor strings, symbolically
 represented as ClassDesc or MethodTypeDesc, depending on
 where a Utf8Entry appear.  Entries representing such uses are created
 with ConstantPoolBuilder.utf8Entry(ClassDesc) and ConstantPoolBuilder.utf8Entry(MethodTypeDesc), and they can be converted to
 symbolic descriptors on a per-use-site basis, such as in AnnotationValue.OfClass.classSymbol() and MethodModel.methodTypeSymbol().
 
 Unlike most constant pool entries, a UTF-8 entry is of flexible length: it is
 represented as an array structure, with an u2 for the data length in
 bytes, followed by that number of bytes of Modified UTF-8 data.  It can
 represent at most 65535 bytes of data due to the physical restrictions.

Method Details- 
stringValueString stringValue()Returns the string value for this entry.- API Note:
- A Utf8Entrycan be used directly as aCharSequenceifStringfunctionalities are not strictly desired. If only string equivalence is desired,equalsStringshould be used. Reduction of string processing can significantly improveclassfile reading performance.
- Returns:
- the string value for this entry
