Nested Class Summary

Nested Classes
Modifier and Type	Class	Description
`static class`	`ConstantExpressions.ConstantEquals`	Represents a binary equals call on two constant expressions.
`static class`	`ConstantExpressions.ConstantExpression`	Represents a constant expression.
`static interface`	`ConstantExpressions.ConstantExpressionVisitor`	Visitor for scanning over the components of a constant expression.
`static class`	`ConstantExpressions.PureMethodInvocation`	Represents both a constant method call or a constant field/local access, depending on the actual type of `symbol`.
`static class`	`ConstantExpressions.Truthiness`	Represents sets of things known to be true and false if a boolean statement evaluated true.

Method Summary

Modifier and Type	Method	Description
`Optional<ConstantExpressions.ConstantExpression>`	`constantExpression(com.sun.source.tree.ExpressionTree tree, VisitorState state)`
`static ConstantExpressions`	`fromFlags(ErrorProneFlags flags)`
`Optional<ConstantExpressions.PureMethodInvocation>`	`symbolizeImmutableExpression(com.sun.source.tree.ExpressionTree tree, VisitorState state)`	Returns a list of the methods called to get to this expression, as well as a terminating variable if needed.
`ConstantExpressions.Truthiness`	`truthiness(com.sun.source.tree.ExpressionTree tree, boolean not, VisitorState state)`	Scans an `ExpressionTree` to find anything guaranteed to be false or true if this expression is true.
