What is the purpose of "&" in the generic type declaration?

In this code , the author creates a class as follows:

public abstract class GlyphIcon<T extends Enum<T> & GlyphIcons> extends Text { /* ... */ }

My question is to understand the meaning of this & in the following snippet:

<T extends Enum<T> & GlyphIcons>

So I noticed, GlyphIcons is an interface. So would that & have the same role as implements ? For example:

<T extends Enum<T> implements GlyphIcons>

Is this (or almost so)?

What does the "&" character mean? when used in generic type declaration?
