Examples of com.ctc.wstx.util.TextBuffer

com.ctc.wstx.util.TextBuffer
TextBuffer is a class similar to {@link StringBuilder}, with following differences:
- TextBuffer uses segments character arrays, to avoid having to do additional array copies when array is not big enough. This means that only reallocating that is necessary is done only once -- if and when caller wants to access contents in a linear array (char[], String).
- TextBuffer is not synchronized.
Over time more and more cruft has accumulated here, mostly to support efficient access to collected text. Since access is easiest to do efficiently using callbacks, this class now needs to known interfaces of SAX classes and validators.
Notes about usage: for debugging purposes, it's suggested to use {@link #toString} method, as opposed to{@link #contentsAsArray} or {@link #contentsAsString}. Internally resulting code paths may or may not be different, WRT caching. @author Tatu Saloranta
