/**
* The standard interface that all implementations of a {@code WebRowSet}
* must implement.
*
* <h3>1.0 Overview</h3>
* The {@code WebRowSetImpl} provides the standard
* reference implementation, which may be extended if required.
* <P>
* The standard WebRowSet XML Schema definition is available at the following
* URI:
* <ul>
* <li>
* <a href="http://java.sun.com/xml/ns/jdbc/webrowset.xsd">http://java.sun.com/xml/ns/jdbc/webrowset.xsd</a>
* </li>
* </ul>
* It describes the standard XML document format required when describing a
* {@code RowSet} object in XML and must be used be all standard implementations
* of the {@code WebRowSet} interface to ensure interoperability. In addition,
* the {@code WebRowSet} schema uses specific SQL/XML Schema annotations,
* thus ensuring greater cross
* platform interoperability. This is an effort currently under way at the ISO
* organization. The SQL/XML definition is available at the following URI:
* <ul>
* <li>
* <a href="http://standards.iso.org/iso/9075/2002/12/sqlxml.xsd">http://standards.iso.org/iso/9075/2002/12/sqlxml.xsd</a>
* </li>
* </ul>
* The schema definition describes the internal data of a {@code RowSet} object
* in three distinct areas:
* <UL>
* <li>properties - These properties describe the standard synchronization
* provider properties in addition to the more general {@code RowSet} properties.
* </li>
* <li>metadata - This describes the metadata associated with the tabular structure governed by a
* {@code WebRowSet} object. The metadata described is closely aligned with the
* metadata accessible in the underlying {@code java.sql.ResultSet} interface.
* </li>
* <li>data - This describes the original data (the state of data since the
* last population
* or last synchronization of the {@code WebRowSet} object) and the current
* data. By keeping track of the delta between the original data and the current data,
* a {@code WebRowSet} maintains the ability to synchronize changes
* in its data back to the originating data source.
* </li>
* </ul>
*
* <h3>2.0 WebRowSet States</h3>
* The following sections demonstrates how a {@code WebRowSet} implementation
* should use the XML Schema to describe update, insert, and delete operations
* and to describe the state of a {@code WebRowSet} object in XML.
*
* <h4>2.1 State 1 - Outputting a {@code WebRowSet} Object to XML</h4>
* In this example, a {@code WebRowSet} object is created and populated with a simple 2 column,
* 5 row table from a data source. Having the 5 rows in a {@code WebRowSet} object
* makes it possible to describe them in XML. The
* metadata describing the various standard JavaBeans properties as defined
* in the RowSet interface plus the standard properties defined in
* the {@code CachedRowSet}™ interface
* provide key details that describe WebRowSet
* properties. Outputting the WebRowSet object to XML using the standard
* {@code writeXml} methods describes the internal properties as follows:
* <PRE>
* {@code
* <properties>
* <command>select co1, col2 from test_table</command>
* <concurrency>1</concurrency>
* <datasource/>
* <escape-processing>true</escape-processing>
* <fetch-direction>0</fetch-direction>
* <fetch-size>0</fetch-size>
* <isolation-level>1</isolation-level>
* <key-columns/>
* <map/>
* <max-field-size>0</max-field-size>
* <max-rows>0</max-rows>
* <query-timeout>0</query-timeout>
* <read-only>false</read-only>
* <rowset-type>TRANSACTION_READ_UNCOMMITTED</rowset-type>
* <show-deleted>false</show-deleted>
* <table-name/>
* <url>jdbc:thin:oracle</url>
* <sync-provider>
* <sync-provider-name>.com.rowset.provider.RIOptimisticProvider</sync-provider-name>
* <sync-provider-vendor>Oracle Corporation</sync-provider-vendor>
* <sync-provider-version>1.0</sync-provider-name>
* <sync-provider-grade>LOW</sync-provider-grade>
* <data-source-lock>NONE</data-source-lock>
* </sync-provider>
* </properties>
* } </PRE>
* The meta-data describing the make up of the WebRowSet is described
* in XML as detailed below. Note both columns are described between the
* {@code column-definition} tags.
* <PRE>
* {@code
* <metadata>
* <column-count>2</column-count>
* <column-definition>
* <column-index>1</column-index>
* <auto-increment>false</auto-increment>
* <case-sensitive>true</case-sensitive>
* <currency>false</currency>
* <nullable>1</nullable>
* <signed>false</signed>
* <searchable>true</searchable>
* <column-display-size>10</column-display-size>
* <column-label>COL1</column-label>
* <column-name>COL1</column-name>
* <schema-name/>
* <column-precision>10</column-precision>
* <column-scale>0</column-scale>
* <table-name/>
* <catalog-name/>
* <column-type>1</column-type>
* <column-type-name>CHAR</column-type-name>
* </column-definition>
* <column-definition>
* <column-index>2</column-index>
* <auto-increment>false</auto-increment>
* <case-sensitive>false</case-sensitive>
* <currency>false</currency>
* <nullable>1</nullable>
* <signed>true</signed>
* <searchable>true</searchable>
* <column-display-size>39</column-display-size>
* <column-label>COL2</column-label>
* <column-name>COL2</column-name>
* <schema-name/>
* <column-precision>38</column-precision>
* <column-scale>0</column-scale>
* <table-name/>
* <catalog-name/>
* <column-type>3</column-type>
* <column-type-name>NUMBER</column-type-name>
* </column-definition>
* </metadata>
* }</PRE>
* Having detailed how the properties and metadata are described, the following details
* how the contents of a {@code WebRowSet} object is described in XML. Note, that
* this describes a {@code WebRowSet} object that has not undergone any
* modifications since its instantiation.
* A {@code currentRow} tag is mapped to each row of the table structure that the
* {@code WebRowSet} object provides. A {@code columnValue} tag may contain
* either the {@code stringData} or {@code binaryData} tag, according to
* the SQL type that
* the XML value is mapping back to. The {@code binaryData} tag contains data in the
* Base64 encoding and is typically used for {@code BLOB} and {@code CLOB} type data.
* <PRE>
* {@code
* <data>
* <currentRow>
* <columnValue>
* firstrow
* </columnValue>
* <columnValue>
* 1
* </columnValue>
* </currentRow>
* <currentRow>
* <columnValue>
* secondrow
* </columnValue>
* <columnValue>
* 2
* </columnValue>
* </currentRow>
* <currentRow>
* <columnValue>
* thirdrow
* </columnValue>
* <columnValue>
* 3
* </columnValue>
* </currentRow>
* <currentRow>
* <columnValue>
* fourthrow
* </columnValue>
* <columnValue>
* 4
* </columnValue>
* </currentRow>
* </data>
* }</PRE>
* <h4>2.2 State 2 - Deleting a Row</h4>
* Deleting a row in a {@code WebRowSet} object involves simply moving to the row
* to be deleted and then calling the method {@code deleteRow}, as in any other
* {@code RowSet} object. The following
* two lines of code, in which <i>wrs</i> is a {@code WebRowSet} object, delete
* the third row.
* <PRE>
* wrs.absolute(3);
* wrs.deleteRow();
* </PRE>
* The XML description shows the third row is marked as a {@code deleteRow},
* which eliminates the third row in the {@code WebRowSet} object.
* <PRE>
* {@code
* <data>
* <currentRow>
* <columnValue>
* firstrow
* </columnValue>
* <columnValue>
* 1
* </columnValue>
* </currentRow>
* <currentRow>
* <columnValue>
* secondrow
* </columnValue>
* <columnValue>
* 2
* </columnValue>
* </currentRow>
* <deleteRow>
* <columnValue>
* thirdrow
* </columnValue>
* <columnValue>
* 3
* </columnValue>
* </deleteRow>
* <currentRow>
* <columnValue>
* fourthrow
* </columnValue>
* <columnValue>
* 4
* </columnValue>
* </currentRow>
* </data>
*} </PRE>
* <h4>2.3 State 3 - Inserting a Row</h4>
* A {@code WebRowSet} object can insert a new row by moving to the insert row,
* calling the appropriate updater methods for each column in the row, and then
* calling the method {@code insertRow}.
* <PRE>
* {@code
* wrs.moveToInsertRow();
* wrs.updateString(1, "fifththrow");
* wrs.updateString(2, "5");
* wrs.insertRow();
* }</PRE>
* The following code fragment changes the second column value in the row just inserted.
* Note that this code applies when new rows are inserted right after the current row,
* which is why the method {@code next} moves the cursor to the correct row.
* Calling the method {@code acceptChanges} writes the change to the data source.
*
* <PRE>
* {@code wrs.moveToCurrentRow();
* wrs.next();
* wrs.updateString(2, "V");
* wrs.acceptChanges();
* }</PRE>
* Describing this in XML demonstrates where the Java code inserts a new row and then
* performs an update on the newly inserted row on an individual field.
* <PRE>
* {@code
* <data>
* <currentRow>
* <columnValue>
* firstrow
* </columnValue>
* <columnValue>
* 1
* </columnValue>
* </currentRow>
* <currentRow>
* <columnValue>
* secondrow
* </columnValue>
* <columnValue>
* 2
* </columnValue>
* </currentRow>
* <currentRow>
* <columnValue>
* newthirdrow
* </columnValue>
* <columnValue>
* III
* </columnValue>
* </currentRow>
* <insertRow>
* <columnValue>
* fifthrow
* </columnValue>
* <columnValue>
* 5
* </columnValue>
* <updateValue>
* V
* </updateValue>
* </insertRow>
* <currentRow>
* <columnValue>
* fourthrow
* </columnValue>
* <columnValue>
* 4
* </columnValue>
* </currentRow>
* </date>
*} </PRE>
* <h4>2.4 State 4 - Modifying a Row</h4>
* Modifying a row produces specific XML that records both the new value and the
* value that was replaced. The value that was replaced becomes the original value,
* and the new value becomes the current value. The following
* code moves the cursor to a specific row, performs some modifications, and updates
* the row when complete.
* <PRE>
*{@code
* wrs.absolute(5);
* wrs.updateString(1, "new4thRow");
* wrs.updateString(2, "IV");
* wrs.updateRow();
* }</PRE>
* In XML, this is described by the {@code modifyRow} tag. Both the original and new
* values are contained within the tag for original row tracking purposes.
* <PRE>
* {@code
* <data>
* <currentRow>
* <columnValue>
* firstrow
* </columnValue>
* <columnValue>
* 1
* </columnValue>
* </currentRow>
* <currentRow>
* <columnValue>
* secondrow
* </columnValue>
* <columnValue>
* 2
* </columnValue>
* </currentRow>
* <currentRow>
* <columnValue>
* newthirdrow
* </columnValue>
* <columnValue>
* III
* </columnValue>
* </currentRow>
* <currentRow>
* <columnValue>
* fifthrow
* </columnValue>
* <columnValue>
* 5
* </columnValue>
* </currentRow>
* <modifyRow>
* <columnValue>
* fourthrow
* </columnValue>
* <updateValue>
* new4thRow
* </updateValue>
* <columnValue>
* 4
* </columnValue>
* <updateValue>
* IV
* </updateValue>
* </modifyRow>
* </data>
* }</PRE>
