java.lang.Object groovy.lang.GroovyObjectSupport groovy.sql.GroovyResultSetExtension
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!

public GroovyResultSetExtension(ResultSet set)
set
- the result set
Method Detail |
---|
public void add(Map values)
values
- a map containing the mappings for column names and values
public void eachRow(Closure closure)
closure
- the closure to perform on each row
public Object getAt(int index)
index
- is the number of the column to look at starting at 1
public Object getProperty(String columnName)
Object
.columnName
- the SQL name of the column
protected ResultSet getResultSet()
public Object invokeMethod(String name, Object args)
public boolean next()
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.
true
if the new current row is valid;
false
if there are no more rows
protected int normalizeIndex(int index)
index
- the raw requested index (may be negative)
public boolean previous()
getResultSet()
object.TYPE_FORWARD_ONLY
true
if the cursor is on a valid row;
false
if it is off the result set
public void putAt(int index, Object newValue)
index
- is the number of the column to look at starting at 1newValue
- the updated value
public void setProperty(String columnName, Object newValue)
Object
value.columnName
- the SQL name of the columnnewValue
- the updated value
public String toString()
