keith-turner opened a new pull request, #84:
URL: https://github.com/apache/accumulo-access/pull/84
This change offers a new parse() method on AccessExpression that creates a
parse tree if one does not exits. This change allows decoupling how access
expression are created (w/ or w/o an initial parse tree) from using parse trees.
For example code the like the following that wanted to use a parse tree to
validate an access expression would have required the ParsedAccessExpression
type to be passed to it. Now it can accept an AccessExpression and call
parse() which will do the most efficient thing depending on how the expression
was created.
```java
void checkExpression(AccessExpression expression){
var parsed = expression.parse();
// use parse tree to validate expression
}
```
