`object` | object | no default | object to be cached
`link` | string | no default | link to corresponding GetGlobal module

Functional Details

This module works with GetGlobal to place and retrieve objects from the cache: SetGlobal places an `object` in the cache, where GetGlobal can retrieve it. SetGlobal should always be used with GetGlobal, not with GetLocal.

Note: The corresponding GetGlobal module must be executed on the same machine (i.e., it cannot be distributed to another machine). See GetGlobal and GetLocal for a discussion of the differences between the Global Get/Set pair and the Local Get/Set pair.

`object` | is the object to be placed in the cache.
`link` | specifies the GetGlobal module that corresponds to the SetGlobal module. In the VPE, this link would be created by dragging an arc from the `link` output of GetGlobal to the `link` input of SetGlobal.

A detailed description of the behavior and use of the GetLocal, GetGlobal, SetLocal, and SetGlobal modules can be found in 4.6 , "Preserving Explicit State" in IBM Visualization Data Explorer User's Guide.
