Constructor Detail

MVResultSet

public MVResultSet()

Construct an empty MVResultSet.

MVResultSet

public MVResultSet(java.lang.String result)
            throws MVException

Construct an MVResultSet from the result string.

Parameters:

result - an Attribute mark delimited string.

Each attribute in the result string will generate one row in the MVResultSet.

Throws:

MVException

Method Detail

next

public boolean next()
             throws MVException

Moves the cursor down one row from its current position. A ResultSet cursor is initially positioned before the first row; the first call to the method next makes the first row the current row; the second call makes the second row the current row, and so on.

Specified by:

next in interface java.sql.ResultSet

Overrides:

next in class AbstractResultSet

Returns:

true if the new current row is valid; false if there are no more rows

Throws:

MVException - if a database access error occurs

close

public void close()
           throws MVException

Closes the result set.

Specified by:

close in interface java.sql.ResultSet

Overrides:

close in class AbstractResultSet

Throws:

MVException - if a database access error occurs

getString

public java.lang.String getString(java.lang.String columnName)
                           throws MVException

Retrieves the value of the designated column in the current row of this ResultSet object as a String in the Java programming language.

Specified by:

getString in interface java.sql.ResultSet

Overrides:

getString in class AbstractResultSet

Parameters:

columnName - the Column name

Returns:

the column value

Throws:

MVException - if current row is not valid

getString

public java.lang.String getString(int columnIndex)
                           throws MVException

Retrieves the value of the designated column in the current row of this ResultSet object as a String in the Java programming language.

Specified by:

getString in interface java.sql.ResultSet

Overrides:

getString in class AbstractResultSet

Parameters:

columnIndex - the first column is 1, the second is 2, ...

Returns:

the column value

Throws:

MVException - if current row is not valid

first

public boolean first()
              throws MVException

Moves the cursor to the first row in this ResultSet object.

Specified by:

first in interface java.sql.ResultSet

Overrides:

first in class AbstractResultSet

Returns:

true if the cursor is on a valid row; false if there are no rows in the result set

Throws:

MVException - if any errors occur

getRow

public int getRow()
           throws MVException

Retrieves the current row number. The first row is number 0, the second number 1, and so on.

Specified by:

getRow in interface java.sql.ResultSet

Overrides:

getRow in class AbstractResultSet

Returns:

the current row number

Throws:

MVException - if any errors occur

setResults

public void setResults(java.lang.String result)
                throws MVException

Populates the result set from the result string.

Parameters:

result - an Attribute mark delimited string

Each attribute in the result string will generate one row in the MVResultSet.

Throws:

MVException - if any errors occur

getRowCount

public int getRowCount()

Returns the number of rows in this result set.

Returns:

row count.

getRows

public java.lang.String[] getRows()

Returns the result set.

Returns:

string array representing the row contents

getCurrentRow

public java.lang.String getCurrentRow()
                               throws MVException

Returns the current row.

Returns:

string the current row

Throws:

MVException - if any errors occur

getColumnCount

public int getColumnCount()

Returns the number of columns in the current result set.

Returns:

count of columns in result set

getColumns

public java.lang.String[] getColumns()

Returns the column names in the current result set.

Returns:

string array containing column names

isQuery

public boolean isQuery()

Returns true if this result set has been generated from an AQL query.

Returns:

true if generated from an AQL query.
