Instance Attribute Summary collapse
-
#cycle_count ⇒ Object
readonly
Returns the value of attribute cycle_count.
-
#group_size ⇒ Object
readonly
Returns the value of attribute group_size.
-
#pipeline ⇒ Object
readonly
Returns the value of attribute pipeline.
-
#vector_count ⇒ Object
readonly
Used to keep track of how many vectors since the last reset of the pipeline (i.e. since pattern start).
Instance Method Summary collapse
-
#<<(vector) ⇒ Object
Add a vector/comment to the pipeline.
-
#empty(options = {}, &block) ⇒ Object
Call at the end to force a flush out of any remaining vectors.
-
#flush(&block) ⇒ Object
If there are complete groups sitting at the top of the pipeline then this will yield them back line by line, stopping after the last complete group and leaving any remaining single vectors in the pipeline.
-
#initialize(group_size) ⇒ VectorPipeline
constructor
A new instance of VectorPipeline.
- #push_comment(comment) ⇒ Object
- #push_microcode(code) ⇒ Object

#vector_count ⇒ Object (readonly)
Used to keep track of how many vectors since the last reset of the pipeline (i.e. since pattern start). This is used to implement padding if there is a minimum vector requirement.

If there are no complete groups present then it will just return
