StringBand (Jodd API Documentation)

java.lang.Object
- jodd.util.StringBand

```
public class StringBand
extends java.lang.Object
```
StringBand is a faster alternative to StringBuilder. Instead of adding strings, they are stored in an internal array. Only at the end of concatenation, when toString() is invoked, strings are joined together in a very fast manner.
To make StringBand even faster, predict the number of joined strings (and not the final string size)!

- Constructor Detail
  - StringBand
```
public StringBand()
```
    Creates an empty StringBand.
  - StringBand
```
public StringBand(int initialCapacity)
```
    Creates an empty StringBand with provided capacity. Capacity refers to internal string array (i.e. number of joins) and not the total string size.
  - StringBand
```
public StringBand(java.lang.String s)
```
    Creates StringBand with provided content.
  - StringBand
```
public StringBand(java.lang.Object o)
```
- Method Detail
  - append
```
public StringBand append(boolean b)
```
    Appends boolean value.
  - append
```
public StringBand append(double d)
```
    Appends double value.
  - append
```
public StringBand append(float f)
```
    Appends float value.
  - append
```
public StringBand append(int i)
```
    Appends int value.
  - append
```
public StringBand append(long l)
```
    Appends long value.
  - append
```
public StringBand append(short s)
```
    Appends short value.
  - append
```
public StringBand append(char c)
```
    Appends a character. This is not efficient as in StringBuilder, since new string is created.
  - append
```
public StringBand append(byte b)
```
    Appends byte value.
  - append
```
public StringBand append(java.lang.Object obj)
```
    Appends string representation of an object. If null, the 'null' string will be appended.
  - append
```
public StringBand append(java.lang.String s)
```
    Appends a string.
  - capacity
```
public int capacity()
```
    Returns array capacity.
  - length
```
public int length()
```
    Returns total string length.
  - index
```
public int index()
```
    Returns current index of string array.
  - setIndex
```
public void setIndex(int newIndex)
```
    Specifies the new index.
  - charAt
```
public char charAt(int pos)
```
    Returns char at given position. This method is not fast as it calculates the right string array element and the offset!
  - stringAt
```
public java.lang.String stringAt(int index)
```
    Returns string at given position.
  - toString
```
public java.lang.String toString()
```
    Joins together all strings into one.
    
    Overrides:
    
    toString in class java.lang.Object
  - expandCapacity
```
protected void expandCapacity()
```
    Expands internal string array by multiplying its size by 2.
  - calculateLength
```
protected int calculateLength()
```
    Calculates string length.
