FilterHelper Methods

Get the localized description for the specified filter symbol.

Get the localized description for the specified filter symbol with a preference for the specified data type.

Determines whether the specified Object is equal to the current Object.

Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.

Get the specified localized text for this item. Obtaining the text is a cascading process from most specific to least specific always using the IDS as the id: 1) Look for the text item in the application's TextItems collection, 2) If not found, look for the item in the locale resource file, 3) If not found, use the provided defaultText.

Gets the filtering helper object to use. The filtering helper provides for filter keyword localization and provides various filtering utility methods. If a helper object already exists for the current culture then that existing object will be returned. If not, a new object will be created and initialized.

Serves as a hash function for a particular type.

Gets the Type of the current instance.

Determines if the specified string includes a conjunction operator and, if so, returns the type of FilterConjunction and the two subclauses.

Get the inverse operator the specific comparison.

Loads the helper's keywords including any localized text avaliable.

Look up a FilterKeyword keyword by its FilterSyms symbol.

Creates a shallow copy of the current Object.

Attempt to parse a filter value for an approximation (+/- or =-) filter. Note that it is the responsibility of the caller to parse and apply the margin.

Determines if the specified string starts with a comparison operator and, if so, returns that operator and the search clause with the operator removed.

Gets the localized text for the specified FilterSyms symbol.

Convert a filtering symbol (from FilterSyms) to its corresponding enumeration.

Returns a String that represents the current Object.

Determines if the object value is equal to another object. If the two objects are null, then this returns true. There is special handling for guid comparisons (since a guid could be a string formatted in up to 3 different ways). If the special guid handling is not performed, then the object.Equals method is used.
