4.11.7 Transferring Strings

Sometimes it is useful to transfer a calculated value from the master to the slave. Instead of having to create a temporary file and then use FileDownload, you can use one of the string download steps.

StringDownload works just like FileDownload except it takes a single argument, s, representing the string to download instead of a mastersrc argument.

JSONStringDownload is similar, except it takes an o argument, which must be json serializable, and transfers that as a json-encoded string to the slave.

JSONPropertiesDownload transfers a json-encoded string that represents a dictionary where properties maps to a dictionary of build property name to property value; and sourcestamp represents the build's sourcestamp.
