DataDataProcessor
Defined in: core/processors/data-processor.svelte.ts:22
Class responsible for processing and transforming data for a datagrid component. It handles various operations such as filtering, sorting, grouping, and pagination, providing an efficient way to transform raw data into a format suitable for the grid.
Type Parameters
• TOriginalRow
The type of the original row data in the datagrid.
Constructors
new DataDataProcessor()
new DataDataProcessor<
TOriginalRow>(datagrid):DataDataProcessor<TOriginalRow>
Defined in: core/processors/data-processor.svelte.ts:31
Constructs an instance of the DataDataProcessor.
Parameters
datagrid
DatagridCore<TOriginalRow>
The core datagrid instance to which this processor belongs.
Returns
DataDataProcessor<TOriginalRow>

Methods
applyColumnFilters()
applyColumnFilters(
data):TOriginalRow[]
Defined in: core/processors/data-processor.svelte.ts:167
Applies column filters to the data. Filters are evaluated on a per-column basis.
Parameters
data
TOriginalRow[]
The raw data to be filtered.
Returns
TOriginalRow[]
The data after applying column filters.
applyFilters()
applyFilters(
data):TOriginalRow[]
Defined in: core/processors/data-processor.svelte.ts:76
Applies filters to the dataset. This includes both global search and column filters.
Parameters
data
TOriginalRow[]
The raw data to be filtered.
Returns
TOriginalRow[]
The filtered data.
applyGlobalSearch()
applyGlobalSearch(
data):TOriginalRow[]
Defined in: core/processors/data-processor.svelte.ts:114
Applies global search to the data, using either fuzzy search or a simple substring match.
Parameters
data
TOriginalRow[]
The raw data to be searched.
Returns
TOriginalRow[]
The data after applying global search.
createHierarchicalData()
createHierarchicalData(
data):GridRow<TOriginalRow>[]
Defined in: core/processors/data-processor.svelte.ts:344
Creates hierarchical data by recursively grouping rows based on the defined grouping columns. Each group can contain child groups, and aggregation functions are applied to each group.
Parameters
data
TOriginalRow[]
The raw data to be grouped.
Returns
GridRow<TOriginalRow>[]
The hierarchical structure of grouped rows.
executeFullDataTransformation()
executeFullDataTransformation():
void
Defined in: core/processors/data-processor.svelte.ts:43
Executes the full data transformation pipeline including filtering, sorting, and grouping, preparing the data for display in the datagrid. This function processes the data, stores intermediate results in cache, and manages pagination.
Returns
void
handleGroupExpansion()
handleGroupExpansion():
void
Defined in: core/processors/data-processor.svelte.ts:474
Handles group expansion and updates the visible rows, pagination, and cached rows accordingly.
If hierarchical rows exist, the visible rows are determined by the expanded group state, otherwise the sorted data is processed. Afterward, the rows are paginated and cached.
Returns
void
handlePaginationChange()
handlePaginationChange():
void
Defined in: core/processors/data-processor.svelte.ts:495
Handles the change in pagination and updates the cached paginated rows accordingly.
This method gets the visible rows based on the current state and then updates the cached paginated rows for the current page.
Returns
void
processGroupedData()
processGroupedData(
data):void
Defined in: core/processors/data-processor.svelte.ts:205
Processes grouped data by organizing it into hierarchical structures based on grouping columns, applying any necessary aggregations and handling visibility based on group expansion state.
Parameters
data
TOriginalRow[]
The raw data to be processed into groups.
Returns
void
registerAggregationFn()
registerAggregationFn(
name,fn):void
Defined in: core/processors/data-processor.svelte.ts:271
Registers a custom aggregation function for use in the datagrid.
Parameters
name
string
The name of the aggregation function.
fn
The aggregation function to register.
Returns
void
