Classes

Query

Defined in: index.ts:201

The Query class is used to search the graph for nodes and edges using the Dependency Selector Syntax (DSS).

Constructors

new Query()
new Query(__namedParameters): Query

Defined in: index.ts:251

Parameters
__namedParameters

QueryOptions

Returns

Query

Methods

search(query, __namedParameters): Promise<QueryResponse>

Defined in: index.ts:442

Search the graph for nodes and edges that match the given query.

Parameters
query

string

__namedParameters

SearchOptions

Returns

Promise<QueryResponse>

getQueryTokens()
static getQueryTokens(query): ParsedSelectorToken[]

Defined in: index.ts:518

Parses a query string in order to retrieve an array of tokens.

Parameters
query

string

Returns

ParsedSelectorToken[]

hasSecuritySelectors()
static hasSecuritySelectors(query): boolean

Defined in: index.ts:213

Helper method to determine if a given query string is using any of the known security selectors. This is useful so that operations can skip hydrating the security archive if it’s not needed.

Parameters
query

string

Returns

boolean

specificitySort()
static specificitySort(responses): QueryResponse[]

Defined in: index.ts:228

Sorts an array of QueryResponse objects by specificity. Objects with higher idCounter values come first, if idCounter values are equal, then objects with higher commonCounter values come first. Otherwise, the original order is preserved.

Parameters
responses

QueryResponse[]

Returns

QueryResponse[]
