Does a composite mast mean several functions or composite material?

Does composite mast mean a mast made of composite materials or one that performs several roles?

In this discussion it means an integrated package of several functions, including electronic warfare, communications, and navigation.

Here, composite refers to several functions packaged together. The Japanese example combines electronic-warfare sensors and systems with communications and navigation equipment. Some available mast packages also include radar. Indian use of a Japanese option and European interest in Saab Kockums are mentioned as examples. The reply does not specify a material construction.
