public class ComposedExpression : FilterExpression

Constructors

ComposedExpression(FilterExpression, Operator, FilterExpression)

Initializes a new instance of the ComposedExpression class with the specified operator and left and right operands.

Declaration

public ComposedExpression(FilterExpression leftOperand, ComposedExpression.Operator op, FilterExpression rightOperand)

Parameters

Type	Name	Description
FilterExpression	leftOperand	The left operand.
ComposedExpression.Operator	op	The operator.
FilterExpression	rightOperand	The right operand.

Properties

LeftOperand

Gets or sets the left operand of this composed expression. Can only be null if the expression is used with the NOT operator.

Declaration

[DataMember]
public FilterExpression LeftOperand { get; set; }

Property Value

Type	Description
FilterExpression

Op

Gets or sets the operator of this composed expression.

Declaration

[DataMember]
public ComposedExpression.Operator Op { get; set; }

Property Value

Type	Description
ComposedExpression.Operator

RightOperand

Gets or sets the right operand of this composed expression. Cannot be null.

Declaration

[DataMember]
public FilterExpression RightOperand { get; set; }

Methods

Evaluate(ITypedKeyValueContainer)

Evaluates a filter expression for a given a set of field values.

Declaration

public override bool Evaluate(ITypedKeyValueContainer values)

Parameters

Type	Name	Description
ITypedKeyValueContainer	values	A set of field values.

Returns

Type	Description
bool	true if the field values satisfy the expression, false otherwise.

Overrides

FilterExpression.Evaluate(ITypedKeyValueContainer)

ToString()

ToString()

Declaration

public override string ToString()

Returns

Type	Description
string	A string representation of the object, for display purposes.

Overrides

object.ToString()

Validate(IFieldDefinitions, bool)

Validates the filter expression against the provided field definitions.

Declaration

public override bool Validate(IFieldDefinitions fields, bool throwIfInvalid)

Parameters

Type	Name	Description
IFieldDefinitions	fields	The field definitions to validate against.
bool	throwIfInvalid	If true, an exception will be thrown if invalid field names are encountered. If false, the return value will be set to false without an exception being thrown.

Returns

Type	Description
bool	true if the filter expression is valid, given the provided field definitions. false otherwise.

Overrides

FilterExpression.Validate(IFieldDefinitions, bool)
