Reference documentation and code samples for the Infrastructure Manager V1 API module Google::Api::ResourceDescriptor::History.

A description of the historical or future-looking state of the
resource pattern.

## Constants

### HISTORY_UNSPECIFIED

**value:** 0  
The "unset" value.

### ORIGINALLY_SINGLE_PATTERN

**value:** 1  
The resource originally had one pattern and launched as such, and
additional patterns were added later.

### FUTURE_MULTI_PATTERN

**value:** 2  
The resource has one pattern, but the API owner expects to add more
later. (This is the inverse of ORIGINALLY_SINGLE_PATTERN, and prevents
that from being necessary once there are multiple patterns.)
