Class RowFilter.Entry<M,I>

java.lang.Object
javax.swing.RowFilter.Entry<M,I>
Type Parameters:
M - the type of the model; for example PersonModel
I - the type of the identifier; when using TableRowSorter this will be Integer
Enclosing class:
RowFilter<M,I>
public abstract static class RowFilter.Entry<M,I> extends Object
An Entry object is passed to instances of RowFilter, allowing the filter to get the value of the entry's data, and thus to determine whether the entry should be shown. An Entry object contains information about the model as well as methods for getting the underlying values from the model.
Since:
1.6

  • Method Details

    • getModel

      public abstract M getModel()
      Returns the underlying model.
      Returns:
      the model containing the data that this entry represents

    • getValueCount

      public abstract int getValueCount()
      Returns the number of values in the entry. For example, when used with a table this corresponds to the number of columns.
      Returns:
      number of values in the object being filtered

    • getValue

      public abstract Object getValue(int index)
      Returns the value at the specified index. This may return null. When used with a table, index corresponds to the column number in the model.
      Parameters:
      index - the index of the value to get
      Returns:
      value at the specified index
      Throws:
      IndexOutOfBoundsException - if index < 0 or >= getValueCount

    • getStringValue

      public String getStringValue(int index)
      Returns the string value at the specified index. If filtering is being done based on String values this method is preferred to that of getValue as getValue(index).toString() may return a different result than getStringValue(index).

      This implementation calls getValue(index).toString() after checking for null. Subclasses that provide different string conversion should override this method if necessary.

      Parameters:
      index - the index of the value to get
      Returns:
      non-null string at the specified index
      Throws:
      IndexOutOfBoundsException - if index < 0 || >= getValueCount

    • getIdentifier

      public abstract I getIdentifier()
      Returns the identifier (in the model) of the entry. For a table this corresponds to the index of the row in the model, expressed as an Integer.
      Returns:
      a model-based (not view-based) identifier for this entry
