M
- the type of the model; for example PersonModel
I
- the type of the identifier; when using TableRowSorter
this will be Integer
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.
RowFilter
, DefaultRowSorter.setRowFilter(javax.swing.RowFilter)
public Entry()
Creates an Entry
.
public abstract M getModel()
Returns the underlying model.
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.
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.
index
- the index of the value to getIndexOutOfBoundsException
- if index < 0 or >= getValueCountpublic 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.
index
- the index of the value to getnon-null
string at the specified indexIndexOutOfBoundsException
- if index < 0 || >= getValueCountpublic 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
.
