# Interface: com.pnfsoftware.jeb.client.api.IClientContext

This important interface represents a client context for scripting. Client contexts are provided to JEB scripts at execution time.

## Method: closeMainProject
- return type: `boolean`

Description: Convenience method used to close the main project \(if any\), that is, the first project of the first engines context managed by the JEB back\-end. If no project is opened, this method will return false.
return: success indicator

## Method: getArguments
- return type: `java.lang.String[]`

Description: Get the input arguments provided to this client context. The returned array depends on how the context was instantiated and called.
return: an array \(possibly empty\) or null if arguments are irrelevant in the current context

## Method: getBaseDirectory
- return type: `java.lang.String`

Description: Get the JEB base directory.
return: the base directory

## Method: getEnginesContext
- return type: `com.pnfsoftware.jeb.core.IEnginesContext`

Description: Get the primary JEB engines context.
return: the primary engines context, possibly null if none was initialized

## Method: getMainProject
- return type: `com.pnfsoftware.jeb.core.IRuntimeProject`

Description: Convenience method used to retrieve the main project \(if any\), that is, the first project of the first engines context managed by the JEB back\-end. If no project is opened, this method will return null.
return: the main project or null

## Method: getMaxMemory
- return type: `long`

Description: Get the theoretical maximum amount of memory that JEB can allocate and use.
return: total theoretical memory that JEB could use, in bytes

## Method: getProcessId
- return type: `long`

Description: Retrieve the process id of the Java VM executing JEB.
return: JEB's PID

## Method: getProgramDirectory
- return type: `java.lang.String`

Description: Get the JEB program directory. Typically, this is the bin/ sub\-directory located within JEB installation folder.
return: the program directory

## Method: getSoftwareVersion
- return type: `com.pnfsoftware.jeb.core.Version`

Description: Get the JEB back\-end software version.
return: the software version

## Method: getTransientStore
- return type: `java.util.Map<java.lang.Object,java.lang.Object>`

Description: Retrieve a reference to the transient store provided by this context. Clients may use this map to store context\-level global objects. The store and its objects are not persisted with a project JDB2 database. 

 Interface specifications for implementations:
 \- Null keys are forbidden, null values are allowed
 \- Insertion, retrieval and deletion are thread\-safe
 \- Iterating is not thread\-safe
 \- The insertion order is not guaranteed during iteration
return: a non\-null read\-write map

## Method: getUsedMemory
- return type: `long`

Description: Get the amount of memory currently used by JEB.
return: used memory in bytes

## Method: open
- parameter: `path`, type: `java.lang.String`
- return type: `com.pnfsoftware.jeb.core.units.IUnit`

Description: Convenience method used to create a JEB project \(or retrieve the current project if one is opened\), load a file artifact into the project, process it, and return the resulting top\-level unit. 

 If the input file is a JDB2 saved project, that project is opened and returned. The method will throw [IllegalStateException](IllegalStateException) if a project is already opened.
parameter: path: input file to be analyzed, or an existing project saved as a JDB2 database            \(\*.jdb2\)
return: the top\-level unit yielded from the analysis of the provided artifact; if the input         path was a JDB2 project, the top\-level unit of the first project's artifact is         returned
throws: on IO error
