  com.zentense.step2.view.View
      com.zentense.step2.view.RowView

Direct Known Subclasses:

VectorRowView

public class RowView
extends View

This class is a view of a single row. A row is a group of pairs (key, value), as in a Hashtable (in fact a RowView is a wrapper of a Hashtable) and this is the simplest view possible and can contain a row or none.

Constructor Detail

RowView

public RowView()

Empty constructor

RowView

public RowView(java.util.Hashtable row)

Constructs a RowView from a Hashtable

Parameters:

row - The (key, value) pairs.

RowView

public RowView(java.util.Vector v)

Constructs a RowView from a Vector. The Vector must be empty (then an empty RowView is constructed), or must contain a Hashtable as the first element that will be used for constructing the RowView.

Parameters:

v - A Vector

Method Detail

setRow

public final void setRow(java.util.Hashtable row)

Sets the row (the Hashtable) of this view.

Parameters:

row - A Hashtable

setRow

public final void setRow(java.util.Vector v)

Sets the row of this view.

Parameters:

v - An empty Vector, or a Vector that contains a Hashtable as the first element.

setRowOp

public final RowView setRowOp(java.util.Vector v)

This method is used internally by 2step.

Parameters:

v - A Vector

Returns:

this RowView

getRow

public final java.util.Hashtable getRow()

Gets the row of this view

Overrides:

getRow in class View

Returns:

A Hashtable with the (key, value) pairs

isEmpty

public final boolean isEmpty()

Is this row empty?

Returns:

true if there is not any pair (key, value)

getSize

public int getSize()
            throws java.lang.Exception

Gets results size

Specified by:

getSize in class View

Returns:

Number of pairs in row

Throws:

set

public void set(java.lang.String colName,
                java.lang.Object obj)
         throws java.lang.Exception

Sets a (key, value) pair

Specified by:

set in class View

Parameters:

colName - Column name (key)

obj - Value

Throws:

java.lang.Exception

get

public java.lang.Object get(java.lang.String colName)

Gets a column value

Specified by:

get in class View

Array of names

Throws:

java.lang.Exception

toString

public java.lang.String toString()

Returns an string representation of this object

Overrides:

toString in class java.lang.Object

Returns:

String representation of the rowview
