Copy constructor
| DataBlock (void* value, unsigned int len, bool copyData = true) | DataBlock | 
Constructs an initialized data block
Parameters:
| value | Data to assign, may be NULL to fill with zeros | 
| len | Length of data, may be zero (then value is ignored) | 
| copyData | True to make a copy of the data, false to just insert the pointer | 
| ~DataBlock () | ~DataBlock | 
[virtual]
Destroys the data, disposes the memory.

[const virtual]
Get a pointer to a derived class given that class name
Parameters:
| name | Name of the class we are asking for | 
Returns: Pointer to the requested class or NULL if this object doesn't implement it
Reimplemented from GenObject.
| const DataBlock&  empty () | empty | 
[static]
A static empty data block
| inline void*  data () | data | 
[const]
Get a pointer to the stored data.
Returns: A pointer to the data or NULL.
| inline unsigned char*  data (unsigned int offs, unsigned int len = 1) | data | 
[const]
Get a pointer to a byte range inside the stored data.
Parameters:
| offs | Byte offset inside the stored data | 
| len | Number of bytes that must be valid starting at offset | 
Returns: A pointer to the data or NULL if the range is not available.
| inline int  at (unsigned int offs, int defvalue = -1) | at | 
[const]
Get the value of a single byte inside the stored data
Parameters:
| offs | Byte offset inside the stored data | 
| defvalue | Default value to return if offset is outside data | 
Returns: Byte value at offset (0-255) or defvalue if offset outside data
| inline bool  null () | null | 
[const]
Checks if the block holds a NULL pointer.
Returns: True if the block holds NULL, false otherwise.
| inline unsigned int  length () | length | 
[const]
Get the length of the stored data.
Returns: The length of the stored data, zero for NULL.
| void  clear (bool deleteData = true) | clear | 
Clear the data and optionally free the memory
Parameters:
| deleteData | True to free the deta block, false to just forget it | 
| DataBlock&  assign (void* value, unsigned int len, bool copyData = true) | assign | 
Assign data to the object
Parameters:
| value | Data to assign, may be NULL to fill with zeros | 
| len | Length of data, may be zero (then value is ignored) | 
| copyData | True to make a copy of the data, false to just insert the pointer | 
| inline void  append (void* value, unsigned int len) | append | 
Append data to the current block
Parameters:
| value | Data to append | 
| len | Length of data | 
| void  append (const DataBlock& value) | append | 
Append data to the current block
Parameters:
| value | Data to append | 
| void  append (const String& value) | append | 
Append a String to the current block
Parameters:
| value | String to append | 
| void  insert (const DataBlock& value) | insert | 
Insert data before the current block
Parameters:
| value | Data to insert | 
| inline void  resize (unsigned int len) | resize | 
Resize (re-alloc or free) this block if required size is not the same as the current one
Parameters:
| len | Required block size | 
| void  truncate (unsigned int len) | truncate | 
Truncate the data block
Parameters:
| len | The maximum length to keep | 
| void  cut (int len) | cut | 
Cut off a number of bytes from the data block
Parameters:
| len | Amount to cut, positive to cut from end, negative to cut from start of block | 
| inline int  operator[] (signed int index) | operator[] | 
[const]
Byte indexing operator with signed parameter
Parameters:
| index | Index of the byte to retrieve | 
Returns: Byte value at offset (0-255) or -1 if index outside data
| inline int  operator[] (unsigned int index) | operator[] | 
[const]
Byte indexing operator with unsigned parameter
Parameters:
| index | Index of the byte to retrieve | 
Returns: Byte value at offset (0-255) or -1 if index outside data
| DataBlock&  operator= (const DataBlock& value) | operator= | 
Assignment operator.
| inline DataBlock&  operator+= (const DataBlock& value) | operator+= | 
Appending operator.
| inline DataBlock&  operator+= (const String& value) | operator+= | 
Appending operator for Strings.
| bool  convert (const DataBlock& src, const String& sFormat,
	const String& dFormat, unsigned maxlen = 0) | convert | 
Convert data from a different format
Parameters:
| src | Source data block | 
| sFormat | Name of the source format | 
| dFormat | Name of the destination format | 
| maxlen | Maximum amount to convert, 0 to use source | 
Returns: True if converted successfully, false on failure
| bool  unHexify (const char* data, unsigned int len, char sep) | unHexify | 
Build this data block from a hexadecimal string representation. Each octet must be represented in the input string with 2 hexadecimal characters. If a separator is specified, the octets in input string must be separated using exactly 1 separator. Only 1 leading or 1 trailing separators are allowed.
Parameters:
| data | Input character string | 
| len | Length of the input string | 
| sep | Separator character used between octets. 0 if no separator is expected | 
Returns: True if the input string was succesfully parsed, false otherwise
| bool  unHexify (const char* data, unsigned int len) | unHexify | 
Build this data block from a hexadecimal string representation. Each octet must be represented in the input string with 2 hexadecimal characters. This method guesses if separators are used. If so the octets in input string must be separated using exactly 1 separator. Only 1 leading or 1 trailing separators are allowed.
Parameters:
| data | Input character string | 
| len | Length of the input string | 
Returns: True if the input string was succesfully parsed, false otherwise
| inline bool  unHexify (const String& data) | unHexify | 
Build this data block from a hexadecimal string representation. This version parses a String and guesses separators presence.
Parameters:
| data | Input character string | 
Returns: True if the input string was succesfully parsed, false otherwise
| String  sqlEscape (char extraEsc) | sqlEscape | 
[const]
Create an escaped string suitable for use in SQL queries
Parameters:
| extraEsc | Character to escape other than the default ones | 
Returns: A string with binary zeros and other special characters escaped
