## Detailed Description

A base class for algorithms that walk recursively over the IR without visiting the same node twice.

This is for passes that are capable of interpreting the IR as a DAG instead of a tree.

## Member Function Documentation

## include() [1/2]

virtual void Halide::Internal::IRGraphVisitor::include | ( | const Expr & |  | ) |

protected virtual

By default these methods add the node to the visited set, and return whether or not it was already there.

If it wasn't there, it delegates to the appropriate visit method. You can override them if you like.

## include() [2/2]

virtual void Halide::Internal::IRGraphVisitor::include | ( | const Stmt & |  | ) |

protected virtual

## visit() [1/48]

void Halide::Internal::IRGraphVisitor::visit | ( | const IntImm * |  | ) |

override protected virtual

These methods should call 'include' on the children to only visit them if they haven't been visited already.
