Méthodes publiques

Méthode	Description
ConvertToFieldPredicate ( BinaryExpression expression, AbstractQueryStructureBinder structureBinder ) : Expression	Converts a BinaryExpression to a field predicate expression, if supported and convertible.
GetFieldSelector ( Expression left, AbstractQueryStructureBinder structureBinder ) : FieldSelectorExpression
GetFieldSelector ( Expression left, AbstractQueryStructureBinder structureBinder, BindingSignatureSupport bindingSignatureSupport ) : FieldSelectorExpression	Gets a FieldSelectorExpression from an expression it the bindingSignatureSupport identifies it as supported.
IsConvertibleBinary ( BinaryExpression expression, AbstractQueryStructureBinder structureBinder ) : bool	Determines whether the supplied BinaryExpression is convertible to a binary in the context of the featureset of the Rebel Framework-supported expression tree.
NegateFieldPredicate ( FieldPredicateExpression fieldPredicateExpression ) : FieldPredicateExpression	Negates a field predicate, i.e. reverses its ValuePredicateType for example Equals will be switched to NotEquals.

Method Details

ConvertToFieldPredicate() public static méthode

Converts a BinaryExpression to a field predicate expression, if supported and convertible.

public static ConvertToFieldPredicate ( BinaryExpression expression, AbstractQueryStructureBinder structureBinder ) : Expression
expression	System.Linq.Expressions.BinaryExpression	The expression.
structureBinder	Rebel.Framework.Linq.CriteriaGeneration.StructureMetadata.AbstractQueryStructureBinder	The structure binder.
Résultat	System.Linq.Expressions.Expression

GetFieldSelector() public static méthode

public static GetFieldSelector ( Expression left, AbstractQueryStructureBinder structureBinder ) : FieldSelectorExpression
left	System.Linq.Expressions.Expression
structureBinder	Rebel.Framework.Linq.CriteriaGeneration.StructureMetadata.AbstractQueryStructureBinder
Résultat	FieldSelectorExpression

GetFieldSelector() public static méthode

Gets a FieldSelectorExpression from an expression it the bindingSignatureSupport identifies it as supported.

public static GetFieldSelector ( Expression left, AbstractQueryStructureBinder structureBinder, BindingSignatureSupport bindingSignatureSupport ) : FieldSelectorExpression
left	System.Linq.Expressions.Expression	The left.
structureBinder	Rebel.Framework.Linq.CriteriaGeneration.StructureMetadata.AbstractQueryStructureBinder	The structure binder.
bindingSignatureSupport	Rebel.Framework.Linq.CriteriaGeneration.StructureMetadata.BindingSignatureSupport	The binding signature support.
Résultat	FieldSelectorExpression

IsConvertibleBinary() public static méthode

Determines whether the supplied BinaryExpression is convertible to a binary in the context of the featureset of the Rebel Framework-supported expression tree.

public static IsConvertibleBinary ( BinaryExpression expression, AbstractQueryStructureBinder structureBinder ) : bool
expression	System.Linq.Expressions.BinaryExpression	The expression.
structureBinder	Rebel.Framework.Linq.CriteriaGeneration.StructureMetadata.AbstractQueryStructureBinder	The structure binder.
Résultat	bool

NegateFieldPredicate() public static méthode

Negates a field predicate, i.e. reverses its ValuePredicateType for example Equals will be switched to NotEquals.

public static NegateFieldPredicate ( FieldPredicateExpression fieldPredicateExpression ) : FieldPredicateExpression
fieldPredicateExpression	FieldPredicateExpression	The field predicate expression.
Résultat	FieldPredicateExpression
