public abstract Class TablePositionBase<TC extends TableColumnBase<S, T>>

Class Inheritance
Known Direct Subclasses
javafx.scene.control.TreeTablePosition, javafx.scene.control.TablePosition
Type Parameters
<TC>
the type of the TableColumnBase
Imports
java.lang.ref.WeakReference
This class is used to represent a single row/column/cell in a table. Concrete subclasses of this abstract class are used in the TableView and TreeTableView APIs to represent which rows/columns/cells are currently selected, focused, being edited, etc. Note that this class is immutable once it is created.

Because the TableView and TreeTableView controls can have different selection modes, the row and column properties in TablePositionBase can be 'disabled' to represent an entire row or column. This is done by setting the unrequired property to -1 or null.

JavaFX 8.0

TablePositionBaseback to summary
protected TablePositionBase(int row, TC tableColumn)

Constructs a TablePositionBase instance to represent the given row/column position in the underlying table instance (which is not part of the abstract TablePositionBase class, but is part of concrete subclasses such as TablePosition and TreeTablePosition). In all cases, all fields inside TablePositionBase instances are referenced weakly so as to prevent memory leaks. This means that it is possible (but unlikely) that the get methods will return null.

Parameters
row:int

The row that this TablePosition is representing.

tableColumn:TC

The TableColumn instance that this TablePosition represents.

Method Detail

public boolean equals(Object obj)

Overrides java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

Parameters
obj:Object

the reference object with which to compare.

Returns:boolean

true if this object is equal to the obj argument; false otherwise.

Annotations

getColumnback to summary
public abstract int getColumn()

The column index that this TablePosition represents in the TableView. It is -1 if the TableView or TableColumn instances are null.

Returns:int

the column index that this TablePosition represents in the TableView

getRowback to summary
public int getRow()

The row that this TablePosition represents in the TableView.

Returns:int

the row that this TablePosition represents in the TableView

getTableColumnback to summary
public TC getTableColumn()

The TableColumn that this TablePosition represents in the TableView.

Returns:TC

the TableColumn that this TablePosition represents in the TableView

public int hashCode()

Overrides java.lang.Object.hashCode.

Returns a hash code for this TablePosition object.

Returns:int

a hash code for this TablePosition object.
