Constructor Detail

BaseOLAPTableView

public BaseOLAPTableView()

Default Constructor

Method Detail

setModel

public void setModel(OLAPDataSetInterface model)

Sets the model on the viewer.

Parameters:

model - an instance of the OLAPDataSetInterface

getModel

public OLAPDataSetInterface getModel()

Returns the viewer's model.

Returns:

an OLAPDataSetInterface model

contentsChanged

public void contentsChanged(com.sas.collection.ContentsChangedEvent cce)

Listens for ContentsChange Events from the Action Provider and update the number of rows/columns accordingly.

Specified by:

contentsChanged in interface com.sas.collection.ContentsChangedListener

Parameters:

cce - ContentChangedEvent.

rowNumbersAreValid

public boolean rowNumbersAreValid()
                           throws OLAPException

Returns whether or not the current start row and end row values are valid given the state of the model.

Returns:

true if start row and end row settings are valid false otherwise.

Throws:

OLAPException

columnNumbersAreValid

public boolean columnNumbersAreValid()
                              throws OLAPException

Returns whether or not the current start column and end column values are valid given the state of the model.

Returns:

true if start column and end column settings are valid false otherwise.

Throws:

OLAPException

toString

public java.lang.String toString()

Description copied from class: BaseTransformation

Returns a string representation of this transformation bean. A new StringWriter will be created and the write(PrintWriter) method will be invoked. The contents of the StringWriter will be returned, which will contain the output from the Transaction Bean.

Note that the toString() method on this class and subclasses calls the write method, which may have undesirable side effects. The request and response objects are set to null, and these objects are often necessary for the proper functioning of the subsequest write method. Actions on the ActionProvider will not work. Debuggers often use toString() to show the value of a variable, and this may cause unexpected behavior while debugging

Overrides:

toString in class BaseTransformation

Returns:

A string representation of the object

initialize

public void initialize()

Initializes the OLAPTableView Object. This method should be called any time the model is initialized.

Specified by:

initialize in class AbstractBaseTableView

initializeRowNumbers

public void initializeRowNumbers()

This method is called when the number of rows needs to be reset to start at row 1. The developmer should not have to call this method, unless actions are being taken on the model directly, bypassing the command processor.

initializeColumnNumbers

public void initializeColumnNumbers()

This method is called when the number of columns needs to be reset to start at column 1. The developmer should not have to call this method, unless actions are being taken on the model directly, bypassing the command processor.

getColumnCount

public int getColumnCount()

Returns the total available columns. This method should only be called if the developer is implementing their own scrolling capabilities and not using the default scrolling capabilities.

Specified by:

getColumnCount in interface ColumnNavigationInterface

Specified by:

getColumnCount in class AbstractBaseTableView

Returns:

total available columns

getRowCount

public int getRowCount()

Returns the total available rows

Specified by:

getRowCount in interface RowNavigationInterface

Specified by:

getRowCount in class AbstractBaseTableView

Returns:

total available rows

isAccurateRowCountAvailable

public boolean isAccurateRowCountAvailable()

Indicates whether an accurate row count is available.

Specified by:

isAccurateRowCountAvailable in interface AccurateRowCountInterface

Specified by:

isAccurateRowCountAvailable in class AbstractBaseTableView

Returns:

true if an accurate row count is available, false otherwise.

setActionProvider

public void setActionProvider(HttpActionProvider actionProvider)

Sets the ActionProvider object

Specified by:

setActionProvider in interface HttpActionProviderInterface

Overrides:

setActionProvider in class BaseActionTransformation

Parameters:

ActionProvider - object

See Also:

HttpActionProviderInterface.getActionProvider()

isGotoRowSupported

public boolean isGotoRowSupported()

Determines whether navigation to any given row is supported. Returns true if scrolling forward and backward are supported.

Specified by:

isGotoRowSupported in interface RowNavigationInterface

Overrides:

isGotoRowSupported in class AbstractBaseTableView

Returns:

true if navigation to any given row is supported

See Also:

AbstractBaseTableView.gotoRow(int)

gotoRow

public void gotoRow(int row)

Navigates to the given row.

Specified by:

gotoRow in interface RowNavigationInterface

Overrides:

gotoRow in class AbstractBaseTableView

Parameters:

row - the row index

Throws:

java.lang.UnsupportedOperationException - Thrown if isGotoRowSupported() returns false

See Also:

isGotoRowSupported()

isGotoColumnSupported

public boolean isGotoColumnSupported()

Determines whether navigation to any given column is supported. Returns true if scrolling forward and backward is supported.

Specified by:

isGotoColumnSupported in interface ColumnNavigationInterface

Overrides:

isGotoColumnSupported in class AbstractBaseTableView

Returns:

true if navigation to any given column is supported

See Also:

AbstractBaseTableView.gotoColumn(int)

gotoColumn

public void gotoColumn(int column)

Navigates to the given column.

Specified by:

gotoColumn in interface ColumnNavigationInterface

Overrides:

gotoColumn in class AbstractBaseTableView

Parameters:

column - the column index

Throws:

java.lang.UnsupportedOperationException - Thrown if isGotoColumnSupported() returns false
