## Detailed Description

A fixed ref counted storage.

This class holds a ref counted storage

## Constructor & Destructor Documentation

RefStorage | ( | const void * | value,
|  | unsigned int | len
| ) |  |
| inline

Constructor

Parameters

  value | Data to assign, may be NULL to fill with zeros
  len | Length of data, may be zero (then value is ignored)

## Member Function Documentation

static bool copy | ( | void * | dest,
|  | const void * | src,
|  | unsigned int | len
| ) |  |
| inline static

Copy data

Parameters

  dest | Destination buffer
  src | Source buffer
  len | The number of bytes to copy

Returns
  True on success, false if parameters are invalid

Referenced by SliceVector< Obj >::copy(), and RefStorage::set().

void* data | ( | unsigned int | offs,
|  | unsigned int | len
| ) |  | const
| inline

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 (must not be 0)

Returns
  A pointer to the data or NULL if the range is not available

References DataBlock::data().

Referenced by RefStorage::set().

static String& dumpSplit | ( | String & | buf,
|  | const String & | str,
|  | unsigned int | lineLen,
|  | unsigned int | offset = `0`,
|  | const char * | linePrefix = `0`,
|  | const char * | suffix = `"\r\n"`
| ) |  |
| static

Split a string and append lines to another one

Parameters

  buf | Destination string
  str | Input string
  lineLen | Line length, characters to copy
  offset | Offset in first line (if incomplete). No data will be added on first line if offset is greater then line length
  linePrefix | Prefix for new lines. Set it to empty string or 0 to use the suffix
  suffix | End of line for the last line

Returns
  Destination string address

static bool equals | ( | const void * | buf1,
|  | const void * | buf2,
|  | unsigned int | len
| ) |  |
| inline static

Compare data

Parameters

  buf1 | First buffer
  buf2 | Second buffer
  len | The number of bytes to compare

Returns
  True if equal

Referenced by SliceVector< Obj >::equals().

static void fill | ( | void * | dest,
|  | unsigned int | len,
|  | int | val = `0`
| ) |  |
| inline static

Fill a buffer

Parameters

  dest | Destination buffer
  len | The number of bytes to fill
  val | Value to fill with

Referenced by SliceVector< Obj >::bzero().

unsigned int length | ( |  | ) | const
| inline

Get the length of the stored data

Returns
  The length of the stored data, zero for NULL

References DataBlock::length().

bool set | ( | const void * | buf,
|  | unsigned int | len,
|  | unsigned int | offs = `0`
| ) |  |
| inline

Copy data to this storage

Parameters

  buf | Buffer to copy
  len | The number of bytes to copy
  offs | The start index in this storage

Returns
  True on success, false if there is not enough space in our storage or the buffer pointer is NULL
