Class Overview
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.

Public Constructors
public RowFilter.Entry ()
Creates an Entry.
Public Methods
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
public abstract M getModel ()
Returns the underlying model.
Returns
- the model containing the data that this entry represents
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-nullstring at the specified index
Throws
| if index < 0 || >= getValueCount |
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
| if index < 0 or >= 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
