public class StringBuilderWriter extends Writer implements Serializable
Writer implementation that outputs to a StringBuilder.
 
 NOTE: This implementation, as an alternative to
 java.io.StringWriter, provides an un-synchronized
 (i.e. for use in a single thread) implementation for better performance.
 For safe usage with multiple Threads then
 java.io.StringWriter should be used.
| Constructor and Description | 
|---|
| StringBuilderWriter()Constructs a new  StringBuilderinstance with default capacity. | 
| StringBuilderWriter(int capacity)Constructs a new  StringBuilderinstance with the specified capacity. | 
| StringBuilderWriter(StringBuilder builder)Constructs a new instance with the specified  StringBuilder. | 
| Modifier and Type | Method and Description | 
|---|---|
| Writer | append(char value)Appends a single character to this Writer. | 
| Writer | append(CharSequence value)Appends a character sequence to this Writer. | 
| Writer | append(CharSequence value,
      int start,
      int end)Appends a portion of a character sequence to the  StringBuilder. | 
| void | close()Closing this writer has no effect. | 
| void | flush()Flushing this writer has no effect. | 
| StringBuilder | getBuilder()Returns the underlying builder. | 
| String | toString()Returns  StringBuilder.toString(). | 
| void | write(char[] value,
     int offset,
     int length)Writes a portion of a character array to the  StringBuilder. | 
| void | write(String value)Writes a String to the  StringBuilder. |
