Interface Summary

Interface	Description
ExtractorBuilder	ExtractorBuilders provide a mechanism to construct a ValueExtractor for a provided cache name, target and property chain (ExtractorBuilder.realize(String, int, String)).
QueryPlus.Dependencies	The Dependencies for QueryPlus.
Statement	Implementations of this interface are able to execute CohQL statements, for example a Select, Update, a backup command etc.
StatementBuilder<T extends Statement>	Classes implementing this interface build instances of Statement implementations.
StatementResult	The result of executing a CohQL Statement.

Class Summary

Class	Description
ChainedExtractorBuilder	An ExtractorBuilder implementation that delegates building ValueExtractors to a chain of ExtractorBuilders and returns the result from the first ExtractorBuilder to return a non-null value from its ChainedExtractorBuilder.realize(String, int, String) method.
CoherenceQueryLanguage	CoherenceQueryLanguage is a simple language for building Filters and doing simple queries that are similar in style to SQL.
ExecutionContext	Instances of this context are passed to Statements to allow commands to discern execution conditions, altering their behavior / result as needed.
FilterBuilder	FilterBuilder is a visitor class that converts a given Abstract Syntax Tree into a Filter.
QueryPlus	QueryPlus implements a simple command line processor for a sql like language.
QueryPlus.DefaultDependencies	A default implementation of QueryPlus.Dependencies.
QueryPlus.DependenciesHelper	The DependenciesHelper provides helper method for constructing QueryPlus.Dependencies implementations for QueryPlus.
ReflectionExtractorBuilder	An ExtractorBuilder implementation that will build instances of ReflectionExtractors.
StatementExecutor	A class that parses and executes CohQL statements read from an instance of a Reader.
UniversalExtractorBuilder	An ExtractorBuilder implementation that will build instances of UniversalExtractors.

Exception Summary

Exception	Description
CohQLException	An exception thrown when errors occur building CohQL queries.
