Java Source Code / Java Documentation » Database Client » SQL Workbench » workbench.util   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    workbench.util.StrBuffer StrBuffer public class StrBuffer implements CharSequence(Code) This is a non-synchronized implementation of StringBuffer, which offers better performance than the class java.lang.StringBuffer. Initially copied from http://h21007.www2.hp.com/dspp/tech/tech_TechDocumentDetailPage_IDX/1,1701,2488,00.html This will only have an advantage if this object is not converted to a String object too often. java.lang.StringBuilder can re-use the internal char[] array when it's toString() method is called, whereas StrBuffer.toString() will allocate a new char array due to the constructor of String. So StrBuffer is most efficient when it is never converted to a String object. For this, methods to write to a Stream and a Writer are provided that write out the internal char array directly. author:    support@sql-workbench.net See Also:   java.lang.StringBuilder Constructor Summary public   StrBuffer()      Make an empty string buffer with 80 characters of storage. public   StrBuffer(String source)      public   StrBuffer(StrBuffer source)      public   StrBuffer(int len)      Make an empty string buffer with 'len' characters of storage.
