pushFromStrategy

public void pushFromStrategy(org.hibernate.hql.ast.common.JoinType joinType,
                             org.antlr.runtime.tree.Tree associationFetchTree,

predicateEquals

public void predicateEquals(String comparativePredicate)

This implements the equality predicate; the comparison predicate could be a constant, a subfunction or some random type parameter. The tree node has all details but with current tree rendering it just passes it's text so we have to figure out the options again.
