#### clone()

  Source:
    - directory/ConnectionMap.js, line 50

#### count()

  Counts the number of elements in the map and fires it into a callback function.

  Inherited From:
    - Gitana.AbstractMap#count
  Source:
    - AbstractMap.js, line 585

#### each(callback)

  Iterates over the map and fires the callback function in SERIAL for each element in the map. The scope for the callback is the object from the map (i.e. repository object, node object).

  The arguments to the callback function are (key, value) where value is the same as "this".

  NOTE: This works against elements in the map in SERIAL. One at a time. If you are doing concurrent remote operations for members of the set such that each operation is independent, you may want to use the eachX() method.

  ##### Parameters:

  Name | Type | Description
  --- | --- | ---
  `callback` |  |

  Inherited From:
    - Gitana.AbstractMap#each
  Source:
    - AbstractMap.js, line 318

#### eachX(callback)

  Iterates over the map and fires the callback function in PARALLEL for each element in the map. The scope for the callback is the object from the map (i.e. repository object, node object).

  The arguments to the callback function are (key, value) where value is the same as "this".

  NOTE: This works against elements in the map in PARALLEL. All map members are fired against at the same time on separate timeouts. There is no guaranteed order for their completion. If you require serial execution, use the each() method.

  ##### Parameters:

  Name | Type | Description
  --- | --- | ---
  `callback` |  |

    - Gitana.AbstractMap#eachX
  Source:
    - AbstractMap.js, line 367

#### extractPrincipalDomainQualifiedId(principal)

  Helper to gets the principal id for a principal object, json structure or principal id itself. This returns something like "domainId/principalId"

  ##### Parameters:

  Name | Type | Description
  --- | --- | ---
  `principal` |  |

  Inherited From:
    - Gitana.Chainable#extractPrincipalDomainQualifiedId
  Source:
    - Chainable.js, line 472

#### extractPrincipalIdentifiers(principal, defaultDomainId)

  Helper to gets the principal id for a principal object, json structure or principal id itself. This returns something like "domainId/principalId"

  ##### Parameters:

  Name | Type | Description
  --- | --- | ---
  `principal` |  | principal object or string (principal id or domain qualified principal id)
  `defaultDomainId` |  |

    - Gitana.Chainable#extractPrincipalIdentifiers
  Source:
    - Chainable.js, line 486

#### filter(callback)

  Iterates over the map and applies the callback filter function to each element. It should hand back true if it wants to keep the value and false to remove it.

  NOTE: the "this" for the callback is the object from the map.

  ##### Parameters:

  Name | Type | Description
  --- | --- | ---
  `callback` |  |

  Inherited From:
    - Gitana.AbstractMap#filter
  Source:
    - AbstractMap.js, line 412

  `response` |  |

  Inherited From:
    - Gitana.AbstractMap#handleResponse
  Source:
    - AbstractMap.js, line 152

#### handleSystemProperties()

  Gets called after the response is handled and allows the object to pull out special values from the "object" field so that they don't sit on the JSON object

  Inherited From:
    - Gitana.AbstractPersistable#handleSystemProperties
  Source:
    - AbstractPersistable.js, line 57

#### json()

  Hands back a cleanup, properties-only JSON simple object.

  Source:
    - AbstractMap.js, line 658

#### sort(comparator)

  Applies a comparator to sort the map.

  If no comparator is applied, the map will be sorted by its modification timestamp (if possible).

  The comparator can be a string that uses dot-notation to identify a field in the JSON that should be sorted. (example: "title" or "property1.property2.property3")

  Finally, the comparator can be a function. It takes (previousValue, currentValue) and hands back: -1 if the currentValue is less than the previousValue (should be sorted lower) 0 if they are equivalent 1 if they currentValue is greater than the previousValue (should be sorted higher)

  ##### Parameters:

  Name | Type | Description
  --- | --- | ---
  `comparator` |  |
