Represents an output port of a workflow.
This call provides access to the underlying structure of the OutputPort. It can only be used for ports of depth >= 1. For singleton ports, use #value instead.
Example usage - To get part of a value from an output port with depth 3: port[0].value(10…100)
# File lib/t2-server/port.rb, line 192 def [](i) return @structure if depth == 0 @structure[i] end
Get the error message (if there is one) of this output port.
This method is only for use on outputs of depth 0. For other depths use ‘port[].error’
# File lib/t2-server/port.rb, line 266 def error return nil unless depth == 0 @structure.error end
Is there an error associated with this output port?
# File lib/t2-server/port.rb, line 179 def error? @error end
Get URI references to the data values of this output port as strings.
For a singleton output a single uri is returned. For lists an array of uris is returned. For an individual reference from a list use ‘port[].reference’.
# File lib/t2-server/port.rb, line 228 def reference @refs = strip(:reference) if @refs.nil? @refs end
Get the data size of the data value in this output port.
For a singleton output a single size is returned. For lists an array of sizes is returned. For an individual size from a list use ‘port[].size’.
# File lib/t2-server/port.rb, line 254 def size @sizes = strip(:size) if @sizes.nil? @sizes end
Return the total data size of all the data in this output port.
# File lib/t2-server/port.rb, line 275 def total_size return @total_size if @total_size if @structure.instance_of? Array return 0 if @structure.empty? @total_size = strip(:size).flatten.inject { |sum, i| sum + i } else @total_size = size end end
Get the mime type of the data value in this output port.
For a singleton output a single type is returned. For lists an array of types is returned. For an individual type from a list use ‘port[].type’.
# File lib/t2-server/port.rb, line 241 def type @types = strip(:type) if @types.nil? @types end
For singleton outputs get the value (or part of it). For list outputs get all the values in an Array structure that mirrors the structure of the output port. To get part of a value from a list use ‘port[].value(range)’.
# File lib/t2-server/port.rb, line 206 def value(range = nil) if depth == 0 if range.nil? @structure.value else @structure.value(range) end else @values = strip(:value) if @values.nil? @values end end
