Class FilterExpressionParser

Provides a parser that can read a filter expression from a string and create an equivalent FilterExpression object.

The returned object can be serialized back into an equivalent string, which may not look exactly like the original input. That is because the parser normalizes the input, by surrounding field names and values with double quotes and by adding brackets.

Field names are case insensitive and so are string values.

Picklist values are case sensitive and the parser will throw an error if the expression contains a value not defined by the specified field.

public FilterExpressionParser(IFieldDefinitions fieldDeclarations)

Parameters

Type	Name	Description
IFieldDefinitions	fieldDeclarations	The field declarations to use for parsing.

Parse(string)

Parses a string expression and returns the equivalent FilterExpression object.

Declaration

public FilterExpression Parse(string s)

Parameters

Type	Name	Description
string	s	The input string.

Returns

Declaration

public static FilterExpression Parse(string expression, IFieldDefinitions fieldDeclarations)

Parameters
