# Pharo Space and Time
An small project to add some statistics generating code for used space and time for Pharo.
Right now it includes only a simple tool to analyze space usage by a graph of objects.
But more to come.
## Installation
```
Metacello new
baseline: 'SpaceAndTime';
repository: 'github://tesonep/spaceAndTime/';
load.
```
## GraphSpaceStatistics
This is the class that can be used to inspect the statistics of space usage of a given graph of objects.
It uses a GraphWalker to get all the recheable objects in the graph.
This object understands messages to access the statistics.
It gives:
- totalInstances: The total number of instances
- totalSizeInBytes: The sum of all the space used by the objects in the graph
- statisticsPerClass: a collection of GraphSpaceStatisticsPerClass with the information for each of the classes the graph have instances.
- statisticsPerClassCSV: a simple CSV to import in your favorite analysis and graphing tool.
### Usage
```
stats := GraphSpaceStatistics new
rootObject: rootOfTheGraph;
yourself.
stats totalSizeInBytes.
stats totalInstances.
stats statisticsPerClass.
stats statisticsPerClassCSV.
```
