public class LuceneFilterableTableModel
extends FilterableTableModel

LuceneFilterableTableModel is a table model which wraps another table model, not including tree table model, so that user can apply filters on it, the filter is working on Lucene mode, which means we will use Lucene Jar to create indexing for the entire table data once you pass the table model in as a parameter or it receives table data change event.

Comparing with FilterableTableModel, LuceneFilterableTableModel has higher performance at filtering part and has more text search options based on Lucene syntax. So if you have a large table and you don't expect your customer to refresh the data of the table very frequently, you can consider using LuceneFilterableTableModel instead of FilterableTableModel. However, if you are expecting your customer refresh the data very frequently or you have a lot of columns with Number class, you probably better use FilterableTableModel.

Please be noted that LuceneFilterableTableModel does not support TreeTableModel.

It's not recommended to wrap two LuceneFilterableTableModel in one model wrapper chain. Because it will consumes twice memory than necessary.

There are two ways to add a filter. One is to add a filter to apply to all the values in the table model using FilterableTableModel.addFilter(com.jidesoft.filter.Filter). Or you can add filter to a particular column using FilterableTableModel.addFilter(int, com.jidesoft.filter.Filter).

By default, filters won't take effect immediately. You need to call setFiltersApplied(true) to apply those filters. If filtersApplied flag is true already, you just need to call refresh(). We don't refresh automatically because you might have several filters to add. You can add all of them, then only call refresh once. setFiltersApplied(int) will control all the filters. Each filter has its own enabled flag which will control each individual filter.

Constructor Detail

LuceneFilterableTableModel

public LuceneFilterableTableModel(TableModel model)

Creates a LuceneFilterableTableModel from any table model.

Parameters:

model - the table model that has the data before filtering.

Method Detail

getFieldNameForColumn

protected String getFieldNameForColumn(int column)

Convert the column name in the table to field in Lucene so that Lucene can handle the field better.

In default implementation, it will remove all the spaces and turn all letters to lower case. It may causes duplicated field for different column name. In this case, you would need override this method.

Parameters:

column - the column index

Returns:

the field name

getDocument

public Document getDocument(int rowIndex)

Get the document for the row.

This method will be invoked by LuceneSupport so that LuceneSupport have documents to indexing and searching. The document must be row(record) based so that LuceneSupport can return a row index(record number) while searching.

Parameters:

rowIndex - the row index (record number)

Returns:

the document to be indexed.

getDocumentCount

public int getDocumentCount()

Get the total number of available documents.

This method will be invoked by LuceneSupport so that LuceneSupport knows how many documents to be indexed and searched at.

Returns:

the number of the available documents.

notifyIndexCreated

public void notifyIndexCreated()

Notify indexing is finished in LuceneSupport so that it is able to do filtering.

This method will be invoked by LuceneSupport when it finishes indexing. You can put actions like filter() in this method so that it can do the first round lucene searching for you.

tableRowsUpdated

protected void tableRowsUpdated(int firstRow,
                    int lastRow)

lastRow - the index of the last row that was updated

tableCellsUpdated

protected void tableCellsUpdated(int column,
                     int firstRow,
                     int lastRow)

Description copied from class: DefaultTableModelWrapper

Called each time the cells in column in the range [firstRow, lastRow] are updated. This default implementation simply fires a corresponding TableModelEvent to the listeners on this model.

Overrides:

tableCellsUpdated in class FilterableTableModel

Parameters:

column - the index of the column that was updated

firstRow - the index of the first row in the above column that was updated

getReservedRows

protected List<Integer> getReservedRows(int firstRow,
                            int lastRow)

Description copied from class: FilterableTableModel

Overrides:

getReservedRows in class FilterableTableModel

Parameters:

firstRow - the first row

lastRow - the last row

Returns:

reserved row list.

filter

protected void filter(boolean filterAllData)

Applies filters and generates a new array of indices.

Overrides:

filter in class FilterableTableModel

Parameters:

filterAllData - if this run of filter have to go through all the rows

getLuceneQuery

protected Query getLuceneQuery()

Get the Query instance used for Lucene filter.

Returns:

the Query instance. null if no filer applied.

convertFilterToLuceneQueryText

protected String convertFilterToLuceneQueryText(int columnIndex,
                                    Filter filter)

Convert Filter to Query text.

In AutoFilterTableHeader scenario, we will call this method to convert filter to query, if we can get a valid Query instance, we can gain the performance by using lucene mechanism. Otherwise we will go back to traditional FilterableTableModel.

So far we only converted SingleValueFilter and MultipleValuesFilter in eachColumnFilter to Query instances. You can convert your desired filter to query as you wish. If you think you cannot convert the filter you encounter, you'd better return null. Otherwise, you probably will lose some effect from the lost filter.

Please be notd that you don't have to add bracket in the outer most but you need add bracket inside this filter.

Parameters:

columnIndex - the index of the column the filter is going to apply

filter - the filter

Returns:

null if you think this filter is not able to converted to query text in some cases. "" if you want to ignore the filter. Otherwise return a valid string.

fireFilterChanged

public void fireFilterChanged(FilterableTableModelEvent e)

Description copied from class: FilterableTableModel

Forwards the given notification event to all FilterableTableModelListeners that registered themselves as listeners for this table model.

Overrides:

fireFilterChanged in class FilterableTableModel

Parameters:

e - the event to be forwarded
