Functions

deepFind

► deepFind(obj: any, path: string): any

Defined in GraphStoreMemory.ts:275

Private helper function used by MemoryDatabase

Returns the part of an object represent by the given path

For example { level1: { level2: { level3: "result" }, level2b: { level3: "not returned" }}}, "level1/level2" returns { level3: "result" }

Parameters:

Param	Type	Description
obj	any	the JSON object to navigate
path	string	the string representation of the path to return

Returns: any the node of the sub-object represented by the path

---

deepUpdate

► deepUpdate(obj: any, path: string, update_value: any): boolean

Defined in GraphStoreMemory.ts:341

Private helper function used by MemoryDatabase

Creates or updates the part of an object represent by the given path

Parameters:

Param	Type	Description
obj	any	the JSON object to navigate
path	string	the string representation of the path to update
update_value	any	the JSON object to create/update at the given location

Returns: boolean true if the item was create, false if was updated

---

objectToSnapshotArray

► objectToSnapshotArray(objectToMap: any): IFireDatabaseSnapshot[]

Defined in GraphStoreMemory.ts:387

Private helper function used by MemoryDatabase

Converts an object to an array of sub-objects and returns as an array of {key, val()} objects

Parameters:

Param	Type	Description
objectToMap	any	the JSON object to convert

Returns: IFireDatabaseSnapshot[] An array of {key, val()} objects

---

subsetFind

► subsetFind(obj: any, path: string): any

Defined in GraphStoreMemory.ts:307

Private helper function used by MemoryDatabase

Returns the part of an object represent by the given path with the root to this node added back in to the result

For example { level1: { level2: { level3: "result" }, level2b: { level3: "not returned" }}}, "level1/level2" returns { level1: { level2: { level3: "result" }}}

Parameters:

Param	Type	Description
obj	any	the JSON object to navigate
path	string	the string representation of the path to return

Returns: any the subset of the entire object represented by this path
