or another element. The join operator is specified in the right operand (EntityRelationBasedJoin).
| |
InnerOuterJoin |
Class which defines a join of type INNER, LEFT or RIGHT.
| |
InPredicateProducers |
Extension methods to produce IN based predicates (field IN (set/range/query)) for field or expression.

| |
JoinClauseBase |
Base class for classes which define a join.
| |
JoinOperandExtensionMethods |
Class which defines extension methods for IJoinOperand implementing types to formulate joins between various elements.
| |
Joins |
Helper class which can create inner/left/right/cross joins based on EntityRelation objects.
| |
LesserEqualOpPredicateProducers |
Extension methods to produce lesser or equal comparison predicates. Defined for various source elements, like fields, expressions...
| |
LesserThanOpPredicateProducers |
Extension methods to produce lesser than comparison predicates. Defined for various source elements, like fields, expressions...
| |
MathFunctions |
Class which defines the function mappings for the Math class
| |
NestedQuerySpecification |
Simple class which contains a nested query specification inside a projection
| |
NotEqualOpPredicateProducers |
Extension methods to produce negated equality (not equal) comparison predicates. Defined for various source elements, like fields, expressions...
| |
NullAwareDataValueProjector |
Specific DataValueProjector, which converts DBNull.Value values from the db to null.
| |
PredicateExtensionMethods |
Extension methods defined for IPredicate implementing classes.
| |
PrefetchPathExtensionMethods |
Extension methods for PrefetchPath related elements.
| |
Projection |
Class which defines the projection of a DynamicQuery
| |
ProjectionLambdaCreator |
Helper class which creates a projection lambda to be used with Select from a type and an IEntityFieldsCore object.
| |
ProjectionLambdaTransformer |
Visitor, which transforms a passed in lambda into a proper projector lambda for WithProjector and extracts the elements to pass to Select(params object[]).
Uses a caching mechanism which caches the compiled result of a lambda based on the string representation of the lambda. This can increase performance.
The caching is tweakable and can be switched off. (See static members of this class). If a lambda contains a constant expression, the lambda isn't cached
to avoid caching a lambda referencing a local variable and keeping the object containing the local variable into memory.
| |
QuerySpec |
Abstract base class for all query specification classes.
| |
QuerySpecExtensionMethods |
Extension ethods defined on QuerySpec and derived classes.
| |
QuerySpecPlaceHolder |
Simple placeholder which is inserted by QueryTarget's join methods and is replaced by a real EntityQuery when the joins are prepared.
| |
QueryTarget |
Placeholder class to specify a join in From() calls on an EntityQuery.
| |
ScalarQueryExtensionMethods |
Extension methods for the ScalarQueryExpression class.
| |
ScalarQueryProducers |

Class which contains extension methods to produce sort clauses on fields / expressions.
| |
StringFunctions |
Class which defines the function mappings for String
| |
StringMethodPredicateProducers |
Extension methods to produce Like predicates for string fields/expressions. Defined for various source elements, like fields, expressions...
| |
Textualizer |
Converts the visited element into a string representation of that element.
| |
TvfCallWrapper |
Simple wrapper class to be able to use a tablevalued function call as a join operand.
|
Interface | Description | |
---|---|---|
IDynamicQuery |
Simple interface for accessing a DynamicQuery object's internal elements for further manipulation (in case of objects) or analysis.
| |
IEntityQuery |
Simple interface for accessing a generic EntityQuery object's internal elements for further manipulation (in case of objects) or analysis.
| |
IJoinOperand |
Interface which defines an operand which can participate in a join definition (as left or right side).
| |
IQuerySpec |
Simple interface for accessing a QuerySpec object's internal elements for further manipulation (in case of objects) or analysis.
|
Delegate | Description | |
---|---|---|
CorrelationFilterFunc |
Delegate which is used to compile an in-memory lambda to which is used to compare parent rows with child rows in nested-query executions.
The lambda looks like:
(parentValues, childValues) => FieldUtilities.ValuesAreEqual(parentValues[parentFieldIndex], childValues[childFieldIndex]);
| |
ObjectCreatorFuncTObject |
Delegate which is used to create new instances of an object based on a type, and which is much faster than Activator.CreateInstance
| |
ProjectionRowDelegateT |
Delegate which is used in WithProjector methods to define the projector delegate.
