SimpleString (Red Hat JBoss Enterprise Application Platform 7.1.0.GA public API)

java.lang.Object
- org.apache.activemq.artemis.api.core.SimpleString

All Implemented Interfaces:

Serializable, CharSequence, Comparable<SimpleString>
```
public final class SimpleString
extends Object
implements CharSequence, Serializable, Comparable<SimpleString>
```
A simple String class that can store all characters, and stores as simple byte[], this minimises expensive copying between String objects.
This object is used heavily throughout ActiveMQ Artemis for performance reasons.

    Specified by:
    
    length in interface CharSequence
  - charAt
```
public char charAt(int pos)
```
    Specified by:
    
    charAt in interface CharSequence
  - subSequence
```
public CharSequence subSequence(int start,
                                int end)

```
    Specified by:
    
    compareTo in interface Comparable<SimpleString>
  - getData
```
public byte[] getData()
```
    returns the underlying byte array of this SimpleString
    
    Returns:
    
    the byte array
  - startsWith
```
public boolean startsWith(SimpleString other)
```
    returns true if the SimpleString parameter starts with the same data as this one. false if not.
    
    Parameters:
    
    other - the SimpleString to look for
    
    Returns:
    
    true if this SimpleString starts with the same data
  - toString
```

    hashCode in class Object
  - split
```
public SimpleString[] split(char delim)
```
    Splits this SimpleString into an array of SimpleString using the char param as the delimiter. i.e. "a.b" would return "a" and "b" if . was the delimiter
    
    Parameters:
    
    delim - The delimiter to split this SimpleString on.
    
    Returns:

```
public SimpleString concat(String toAdd)
```
    Concatenates a SimpleString and a String
    
    Parameters:
    
    toAdd - the String to concatenate with.
    
    Returns:
    
    the concatenated SimpleString
  - concat
```
public SimpleString concat(SimpleString toAdd)

    the concatenated SimpleString
  - sizeof
```
public int sizeof()
```
    returns the size of this SimpleString
    
    Returns:
    
    the size
  - sizeofString
```
public static int sizeofString(SimpleString str)
```
    returns the size of a SimpleString
    
    Parameters:
    
    str - the SimpleString to check
    
    Returns:
    
    the size
  - sizeofNullableString
```
public static int sizeofNullableString(SimpleString str)
```
    returns the size of a SimpleString which could be null
    
    Parameters:
    
    str - the SimpleString to check
    
    Returns:
    
    the size
