Package com.blazebit.expression

Blaze-Expression is a toolkit that allows to model expressions with domain models that can be evaluated and serialized.

Interface Summary

Interface	Description
ArithmeticExpression	The base interface for arithmetic expressions.
Expression	The base interface for an expression.
Expression.ResultVisitor<T>	A visitor for an expression that produces a result as part of the visitation.
Expression.Visitor	A visitor for an expression.
ExpressionCompiler	A compiler for expression strings based on a domain model.
ExpressionCompiler.Context	A compiler context that returns the domain type for available root variables.
ExpressionInterpreter	An interpreter for expressions based on a set of root variable object assignments.
ExpressionInterpreter.Context	An interpreter context that gives access to root variable domain type mappings, root variable object assignments and configuration properties.
ExpressionSerializer<T>	A serializer for expressions that serializes to a serialization target.
ExpressionSerializer.Context	A serialization context that gives access to context parameters.
ExpressionServiceFactory	A factory for expression related functionality based on a domain model.
Predicate	The base interface for predicates.

Class Summary

Class	Description
