## Template for each generated AutoValue_Foo_CustomFieldSerializer class.
## This template uses the Apache Velocity Template Language (VTL).
## The variables ($pkg, $props, and so on) are defined by the fields of
## GwtSerialization.GwtTemplateVars.
##
## Comments, like this one, begin with ##. The comment text extends up to and including the newline
## character at the end of the line. So comments also serve to join a line to the next one.
## Velocity deletes a newline after a directive (#if, #foreach, #end etc) so ## is not needed there.
## That does mean that we sometimes need an extra blank line after such a directive.
##
## A post-processing step will remove unwanted spaces and blank lines, but will not join two lines.
## TODO(emcmanus): perform the post-processing.
#if (!$pkg.empty)
package $pkg;
#end
## The following line will be replaced by the required imports during post-processing.
`import`
#if (!$generated.empty)
@${generated}("com.google.auto.value.processor.AutoValueProcessor")
#else
// Generated by com.google.auto.value.processor.AutoValueProcessor
#end
