Detailed Description

Rule-based graph transformer that provides an API to register rewrite rules and an API to apply all applicable rules to a Graph.

Represents an IGraphTransformer determined by a set of rewrite rules. The transformer will apply all the rewrite rules iteratively as determined by the underlying rewriting strategy. Several rewriting-strategies are possible when traversing the graph and applying rewrite rules, each with different trade offs. At the moment, we define one that performs top-down traversal of nodes.

: Is a bottom-up traversal more efficient? : Is it worth adding the max number of passes a rule should be applied for? : We need to define a contract about whether a rewrite rule is allowed to leave the graph in an inconsistent state (this will determine when and where we will be calling Graph::resolve().

protected

Applies the given set of rewrite rules on the Node of this Graph.

Parameters

[in]	graph	The Graph.
[in]	node	The Node to apply the rules to.
[in]	rules	The vector of RewriteRules that will be applied to the Node.
[out]	rule_effect	Enum that indicates whether and how the graph was modified as a result of applying rules on this node.

Returns: Status indicating success or providing error information.

const InlinedVector<std::reference_wrapper<const RewriteRule> >* onnxruntime::RuleBasedGraphTransformer::GetAnyOpRewriteRules ( ) const

inline

Gets the rewrite rules that are evaluated on all nodes irrespective of their op type.

Returns: a pointer to the vector containing all such rewrite rules or nullptr if no such rule.

const InlinedVector<std::reference_wrapper<const RewriteRule> >* onnxruntime::RuleBasedGraphTransformer::GetRewriteRulesForOpType ( const std::string & op_type ) const

inline

Gets the list of registered rewrite rules that will be triggered on nodes with the given op type by this rule-based transformer.

Returns: a pointer to the vector containing all the registered rewrite rules.

Definition at line 42 of file rule_based_graph_transformer.h.
