## Template for each generated AutoValue_Foo class.
## This template uses the Apache Velocity Template Language (VTL).
## The variables ($pkg, $props, and so on) are defined by the fields of AutoValueTemplateVars.
##
## Comments, like this one, begin with ##. The comment text extends up to and including the newline
## character at the end of the line. So comments also serve to join a line to the next one.
## Velocity deletes a newline after a directive (#if, #foreach, #end etc) so ## is not needed there.
## That does mean that we sometimes need an extra blank line after such a directive.
##
## Post-processing will remove unwanted spaces and blank lines, but will not join two lines.
## It will also replace classes spelled as (e.g.) `java.util.Arrays`, with the backquotes, to
## use just Arrays if that class can be imported unambiguously, or java.util.Arrays if not.

## Get #equalsThatExpression($p) and #hashCodeExpression($p).
#parse("equalshashcode.vm")

#if (!$pkg.empty)
package $pkg;
#end

## The following line will be replaced by the required imports during post-processing.
`import`

${gwtCompatibleAnnotation}
#foreach ($a in $annotations)
$a
#end
#if (!$generated.empty)
@${generated}("com.google.auto.value.processor.AutoValueProcessor")
#else

    ## We don't need a null check if the type is primitive or @Nullable. We also don't need it
    ## if there is a builder, since the build() method will check for us. However, if there is a
    ## builder but there are also extensions (!$isFinal) then we can't omit the null check because
    ## the constructor is called from the extension code.
