type

protected final int type

Protocol Buffer type of this extension; one of the TYPE_ constants.

clazz

protected final java.lang.Class<T> clazz

Java type of this extension. For a singular extension, this is the boxed Java type for the Protocol Buffer type; for a repeated extension, this is an array type whose component type is the unboxed Java type for type. For example, for a singular int32/TYPE_INT32 extension, this equals Integer.class; for a repeated int32 extension, this equals int[].class.

tag

public final int tag

Tag number of this extension. The data should be viewed as an unsigned 32-bit value.

repeated

protected final boolean repeated

Whether this extension is repeated.
