java - 增量搜索方法的伪代码

Question

public boolean searchSummaryData(String textToFind) {
int fromRow, fromCol;

fromRow = summaryTable.getSelectedRow();
fromCol = summaryTable.getSelectedColumn();

if (fromRow < 0) {
    fromRow = 0; //set to start point, first row 
}
if (fromCol < 0) {
    fromCol = 0;
} else if (fromCol == lastFoundCol) {
    fromCol++;
}
int searchIteration = 1;

if (fromRow != 0 || fromCol != 0) {
    searchIteration = 2;
}
for (int iterate = 1; iterate <= searchIteration; iterate++) {
    for (int i = fromRow; i < summaryTableModel.getRowCount(); i++) {
        for (int j = fromCol; j < summaryTableModel.getColumnCount(); j++) {
            final Object valueAt = summaryTableModel.getValueAt(i, j); //point to object at i,j
            if (valueAt != null) {
                textToFind = textToFind.toLowerCase();
                if (valueAt.toString().toLowerCase().contains(textToFind)) {
                    //Map the index of the column/row in the table model at j/i to the index of the column/row in the view.
                    int convertRowIndexToView = summaryTable.convertRowIndexToView(i);
                    int convertColIndexToView = summaryTable.convertColumnIndexToView(j);
                    summaryTable.setRowSelectionInterval(i, i);
                    summaryTable.setColumnSelectionInterval(j, j);
                    //Return a rectangle for the cell that lies at the intersection of row and column.
                    Rectangle rectToScrollTo = summaryTable.getCellRect(convertRowIndexToView, convertColIndexToView, true);
                    tableSp.getViewport().scrollRectToVisible(rectToScrollTo);
                    lastFoundCol = j;
                    return true;
                }
            }
        }
        fromCol = 0;
    }
    fromRow = fromCol = 0;
}
return false;

上述方法的伪代码是什么？我正在努力理解状态变化。它应该对作为此方法的参数提供的文本的 JTable 进行增量搜索。

Answer 1

// if the selection is (0, 0) prepare to skip the second search

// for each cell starting at the selection (first search)
    // get the value
    // if it exists and matches the search string
        // select that cell and scroll to show it
        // mark cell as last found
        // return true to show you found something
// if nothing was found, repeat the above starting from (0,0)

// if still nothing found, return false to say the desired string is not present.
