Syntax

[DataContract]
public class AtomicExpression : FilterExpression

Constructors

AtomicExpression(FieldValue, Operator)

Initializes a new instance of the AtomicExpression class with the given field, value and operator. Throws an error if the field type is not compatible with the operator.

Declaration

public AtomicExpression(FieldValue value, AtomicExpression.Operator op)

Parameters

Type	Name	Description
FieldValue	value	The field value containing both the field name and the value to use for comparison.
AtomicExpression.Operator	op	The operator.

Properties

Op

Gets or sets the operator for this atomic expression. Throws an error if the field type is not compatible with a specific operator.

See description of enum Operator values for a list of compatible types and operators.

Declaration

[DataMember(Order = 1)]
public AtomicExpression.Operator Op { get; set; }

Property Value

Type	Description
AtomicExpression.Operator

Value

Gets or sets the Value for this atomic expression. This property contains both the left and right operands. The Name property of the field represents the left operand and the Value property represents the right operand.

This property should be set before the operator Op property.

Declaration

[DataMember(Order = 0)]
public FieldValue Value { get; set; }

Property Value

Type	Description
FieldValue

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)
