Examples of javolution.text.CharArray

javolution.text.CharArray
This class represents a {@link CharSequence}backed up by a char array. Instances of this class are typically used/reused to provide CharSequence views over existing character buffers.

Instances of this classes have the following properties:
- They support equality or lexical comparison with any CharSequence (e.g. String).
- They have the same hashcode than String and can be used to retrieve data from maps for which the keys are String instances.
- They support fast conversions to primitive types (e.g. {@link #toBoolean() Boolean}, {@link #toInt int}).
