Description

Defines a kind of DataFilter.Filter which applies to text filters. A text filter specifies a string which should be used for filtering and leaves it up to the DataProvider to decide which fields are filtered and how the filtering happens (such as whether the filtering is an exact match or contains, etc).


Usage

Signature:

interface TextFilter<D> extends TextFilterDef, BaseDataFilter<D>

Fields

text :string

Specifies the text to filter for. It is up to the DataProvider implementation to decide which attributes to apply the filter to and also the exact filtering logic used, such as case insensitivity, etc. In addition, for attributes which contain non-string values, the type coercion rule expected is to call toString() on that value. If the value is an object which does not have a string representation then the value does not satisfy the filter.

Methods

filter(item: D, index?: number, array?: Array<D>): boolean;

Specifies a filter function which has the same signature as the the callback which is specified for the JS Array.filter(): https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter This function will be optionally used by the DataProvider to do local filtering. This function is required by the DataProvider so that it is possible for DataProvider implementations to at least do local filtering.
Parameters:
Name Type Argument Description
item any The current element being processed in the array.
index number <optional>
