Class GroovyResultSetExtension

java.lang.Object
groovy.lang.GroovyObjectSupport
groovy.sql.GroovyResultSetExtension
All Implemented Interfaces:
GroovyObject
public class GroovyResultSetExtension
extends GroovyObjectSupport
GroovyResultSetExtension implements additional logic for ResultSet. Due to the version incompatibility between java6 and java5 this methods are moved here from the original GroovyResultSet class. The methods in this class are used by the proxy GroovyResultSetProxy, which will try to invoke methods on this class before invoking it on ResultSet.

This class is not intended to be used directly. Should be used through GroovyResultSetProxy only!

    • putAt

      public void putAt​(int index, java.lang.Object newValue) throws java.sql.SQLException
      Supports integer based subscript operators for updating the values of numbered columns starting at zero. Negative indices are supported, they will count from the last column backwards.

    • normalizeIndex

      protected int normalizeIndex​(int index) throws java.sql.SQLException
      Takes a zero based index and convert it into an SQL based 1 based index. A negative index will count backwards from the last column.
      Parameters:
      index - the raw requested index (may be negative)
      Returns:
      a JDBC index
      Throws:
      java.sql.SQLException - if some exception occurs finding out the column count

    • eachRow

      public void eachRow​(Closure closure) throws java.sql.SQLException
      Call the closure once for each row in the result set.
      Parameters:
      closure - the closure to perform on each row
      Throws:
      java.sql.SQLException - if something goes wrong

    • next

      public boolean next() throws java.sql.SQLException
      Moves the cursor down one row from its current position. A getResultSet() 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.

      If an input stream is open for the current row, a call to the method next will implicitly close it. A getResultSet() object's warning chain is cleared when a new row is read.

      Returns:
      true if the new current row is valid; false if there are no more rows
      Throws:
      java.sql.SQLException - if a database access error occurs

    • previous

      public boolean previous() throws java.sql.SQLException
      Moves the cursor to the previous row in this getResultSet() object.
      Returns:
      true if the cursor is on a valid row; false if it is off the result set
      Throws:
      java.sql.SQLException - if a database access error occurs or the result set type is TYPE_FORWARD_ONLY
