Detailed Description

Vanilla graph node.

Definition at line 429 of file trfGraph.py.

Constructor & Destructor Documentation

__init__()

def python.trfGraph.graphNode.__init__	(		self,
			name,
			inData,
			outData,
			weight = None
	)

Graph node constructor.

Parameters

name	Name of this node
indata	Iterable containing input data connections for this node
outdata	Iterable containing output data connections for this node
weight	Weights (relative execution cost) for each input connection to this node

Note

For inData and outData a list, tuple or set is acceptable. Multiple input data types should be expressed as lists or tuples themselves, e.g., [('HIST_AOD', 'HIST_ESD')]. They cannot be sets themselves as python sets cannot contain other sets.

Definition at line 439 of file trfGraph.py.

    def __init__(self, name, inData, outData, weight = None):
        self._name = name
        self._inData = set(inData)
        self._outData = set(outData)
 
        
        self._inWeights = {}
        if weight is None:
            for data in self._inData:
                self._inWeights[data] = 1
        elif isinstance(weight, int):
            for data in self._inData:
                self._inWeights[data] = weight
        else:
            # Must be a dictionary with its keys equal to the _inData elements
            self._inWeights = weight
 
        self._inputDataTypes = self._flattenSet(self._inData)
        self._outputDataTypes = self._flattenSet(self._outData)
        
        # Connections dictionary will hold incoming and outgoing edges - the incoming connections
        # are very useful for topological ordering. Nested dictionary with 'in', 'out' keys, where
        # the values are dictionaries with nodeName keys and set(dataTypes) as values.
        # e.g., {'out': {'_end_HIST': set(['HIST'])}, 'in': {'ESDtoAOD': set(['HIST_AOD']), 'RAWtoESD': set(['HIST_ESD'])}}
        self._connections = {'in': {}, 'out': {}}
