$ cnpm install ah-preprocessors
Preprocessors of data provided by ah-collector.
npm install ah-preprocessors
Creates a Cloner instance which is just a thin wrapper on top of facile-clone and clones an object preserving Buffers and strings according to the options supplied.
Parameters
$0
Object options applied when cloning objects
Clones the object according to the options supplied in the constructor.
Parameters
x
Object the object to cloneReturns Object the cloned object
Creates an instance of ResourceProcessor. Never call this directly, instead extend it to create a specific processor for your particular resource type, i.e. NetworkResourceProcessor
.
Makes sure that each resource is only processed once.
Parameters
$0
Object options specifying if arguments and function source are captured and how they are cloned
$0.cloner
Cloner used to clone the resource information$0.captureArguments
Boolean? if true
arguments of callbacks are captured when they are processed. (optional, default false
)$0.captureSource
Boolean? if true
the source code of callbacks is captured when they are processed. (optional, default false
)Cleans up all captured resources which means that they are processed, meaningful data extracted and the reference to the actual resource removed so it can be GCed.
Parameters
activities
Object the activities whose resources should be cleanedcollectFunctionInfo
Boolean? if true
it will collect info of all functions found on the hooks resources. (optional, default false
)Cleans the particular resource of the activity found by the uid as part of the activities. If the uid isn't found in the activities or the activity is null
this function returns without doing anything.
Parameters
uid
(Number | String) the id that identifies the activity whose resource should be cleanedactivities
Map<(Number | String), Object> the activities that contain the activity whose resource should be cleanedcollectFunctionInfo
Boolean? if true
it will collect info of all functions found on the hooks resources. (optional, default false
)Scouts functions using function-scout and then adapts the data according to the supplied options. In the process clones function arguments as well and appends them to the returned function info
This function is used by the ResourceProcessor
and most likely you won't have to call it directly.
Sample return value:
[ { path: [ 'owner', '_events', 'connection' ],
key: 'connection',
level: 2,
info:
FunctionOrigin {
file: '/Volumes/d/dev/js/async-hooks/ah-net/test/one-tcp-server.listen+close.js',
line: 25,
column: 21,
inferredName: '',
name: 'onconnection' },
id: 2,
arguments: null }]
Parameters
ctx
Object the context that should be scouted for functionsuid
Number the id which is appended to each function info$0
Object options specifying if arguments and function source are captured and how they are cloned
$0.captureArguments
Boolean? if true
arguments of callbacks are captured when they are processed. (optional, default false
)$0.captureSource
Boolean? if true
the source code of callbacks is captured when they are processed. (optional, default false
)$0.cloner
Cloner used to clone the function arguments$0.name
String? if supplied it will be prepended to all function paths (optional, default null
)Returns Array<Object> array of function information elements, one for each function encountered
