Class StrBuilder

java.lang.Object
org.apache.commons.lang3.text.StrBuilder
All Implemented Interfaces:
Serializable, Appendable, CharSequence, Builder<String>
@Deprecated public class StrBuilder extends Object implements CharSequence, Appendable, Serializable, Builder<String>
Deprecated.
As of 3.6, use Apache Commons Text TextStringBuilder instead
Builds a string from constituent parts providing a more flexible and powerful API than StringBuffer.

The main differences from StringBuffer/StringBuilder are:

  • Not synchronized
  • Not final
  • Subclasses have direct access to character array
  • Additional methods
    • appendWithSeparators - adds an array of values, with a separator
    • appendPadding - adds a length padding characters
    • appendFixedLength - adds a fixed width field to the builder
    • toCharArray/getChars - simpler ways to get a range of the character array
    • delete - delete char or string
    • replace - search and replace for a char or string
    • leftString/rightString/midString - substring without exceptions
    • contains - whether the builder contains a char or string
    • size/clear/isEmpty - collections style API methods
  • Views
    • asTokenizer - uses the internal buffer as the source of a StrTokenizer
    • asReader - uses the internal buffer as the source of a Reader
    • asWriter - allows a Writer to write directly to the internal buffer

The aim has been to provide an API that mimics very closely what StringBuffer provides, but with additional methods. It should be noted that some edge cases, with invalid indices or null input, have been altered - see individual methods. The biggest of these changes is that by default, null will not output the text 'null'. This can be controlled by a property, setNullText(String).

Prior to 3.0, this class implemented Cloneable but did not implement the clone method so could not be used. From 3.0 onwards it no longer implements the interface.

      Returns:
      this, to enable chaining

    • appendWithSeparators

      public StrBuilder appendWithSeparators(Iterator<?> it, String separator)
      Deprecated.
      Appends an iterator placing separators between each value, but not before the first or after the last. Appending a null iterator will have no effect. Each object is appended using append(Object).
      Parameters:

      Parameters:
      array - the array to append
      separator - the separator to use, null means no separator
      Returns:
      this, to enable chaining

    • asReader

      public Reader asReader()
      Deprecated.
      Gets the contents of this builder as a Reader.

      This method allows the contents of the builder to be read using any standard method that expects a Reader.

      To use, simply create a StrBuilder, populate it with data, call asReader, and then read away.

      The internal character array is shared between the builder and the reader. This allows you to append to the builder after creating the reader, and the changes will be picked up. Note however, that no synchronization occurs, so you must perform all operations with the builder and the reader in one thread.

      The returned reader supports marking, and ignores the flush method.

      Returns:
      a reader that reads from this builder

    • asTokenizer

      public StrTokenizer asTokenizer()
      Deprecated.
      Creates a tokenizer that can tokenize the contents of this builder.

      This method allows the contents of this builder to be tokenized. The tokenizer will be setup by default to tokenize on space, tab, newline and formfeed (as per StringTokenizer). These values can be changed on the tokenizer class, before retrieving the tokens.

      The returned tokenizer is linked to this builder. You may intermix calls to the builder and tokenizer within certain limits, however there is no synchronization. Once the tokenizer has been used once, it must be reset to pickup the latest changes in the builder. For example: 

       StrBuilder b = new StrBuilder();
 b.append("a b ");
 StrTokenizer t = b.asTokenizer();
 String[] tokens1 = t.getTokenArray();  // returns a,b
 b.append("c d ");
 String[] tokens2 = t.getTokenArray();  // returns a,b (c and d ignored)
 t.reset();              // reset causes builder changes to be picked up
 String[] tokens3 = t.getTokenArray();  // returns a,b,c,d

      In addition to simply intermixing appends and tokenization, you can also call the set methods on the tokenizer to alter how it tokenizes. Just remember to call reset when you want to pickup builder changes.

      Calling StrTokenizer.reset(String) or StrTokenizer.reset(char[]) with a non-null value will break the link with the builder.

      Returns:
      a tokenizer that is linked to this builder

    • asWriter

      public Writer asWriter()
      Deprecated.
      Gets this builder as a Writer that can be written to.

      This method allows you to populate the contents of the builder using any standard method that takes a Writer.

      To use, simply create a StrBuilder, call asWriter, and populate away. The data is available at any time using the methods of the StrBuilder.

      The internal character array is shared between the builder and the writer. This allows you to intermix calls that append to the builder and write using the writer and the changes will be occur correctly. Note however, that no synchronization occurs, so you must perform all operations with the builder and the writer in one thread.

      The returned writer ignores the close and flush methods.

      Returns:
      a writer that populates this builder
