## javax.swing
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
See Also:
  `RowFilter`, `DefaultRowSorter.setRowFilter(javax.swing.RowFilter)`

Constructor Summary
`RowFilter.Entry()` Creates an `Entry`.

Method Summary
`abstract I` | `getIdentifier()` Returns the identifer (in the model) of the entry.
`abstract M` | `getModel()` Returns the underlying model.
`String` | `getStringValue(int index)` Returns the string value at the specified index.
`abstract Object` | `getValue(int index)` Returns the value at the specified index.
`abstract int` | `getValueCount()` Returns the number of values in the entry.

Constructor Detail

### RowFilter.Entry

    public RowFilter.Entry()

  Creates an `Entry`.

Method Detail

### 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 identifer (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
