endpoint_serializer function

Endpoint Serializer with Hooks

This method allows serializers to return preexec, postexec, and aroundexec ( ) hooks in addition to a serializer. This is useful for graphics device serializers which need a preexec and postexec hook to capture the graphics output.

endpoint_serializer(
  serializer,
  preexec_hook = NULL,
  postexec_hook = NULL,
  aroundexec_hook = NULL
)

Arguments

• serializer: Serializer method to be used. This method should already have its initialization arguments applied.
• preexec_hook: Function to be run directly before a PlumberEndpoint calls its route method.
• postexec_hook: Function to be run directly after a PlumberEndpoint calls its route method.
• aroundexec_hook: Function to be run around a PlumberEndpoint call. Must handle a .next argument to continue execution.

Details

preexec and postexec hooks happened directly before and after a route is executed. These hooks are specific to a single PlumberEndpoint 's route calculation.

Examples

# The definition of `serializer_device` returns
# * a `serializer_content_type` serializer
# * `aroundexec` hook
print(serializer_device)
