Package Summary  Overview Summary

class:RowSetMetaDataImpl [NONE]

  • All Implemented Interfaces:
    Serializable, ResultSetMetaData, Wrapper, RowSetMetaData

    public class RowSetMetaDataImpl
    extends Object
    implements RowSetMetaData, Serializable
    
    Provides implementations for the methods that set and get metadata information about a RowSet object's columns. A RowSetMetaDataImpl object keeps track of the number of columns in the rowset and maintains an internal array of column attributes for each column.

    A RowSet object creates a RowSetMetaDataImpl object internally in order to set and retrieve information about its columns.

    NOTE: All metadata in a RowSetMetaDataImpl object should be considered as unavailable until the RowSet object that it describes is populated. Therefore, any RowSetMetaDataImpl method that retrieves information is defined as having unspecified behavior when it is called before the RowSet object contains data.

    Indicates whether the designated column is definitely not writable, thus readonly.
    Specified by:
    isReadOnly in interface ResultSetMetaData
    Parameters:
    columnIndex - the first column is 1, the second is 2, and so on; must be between 1 and the number of columns, inclusive
    Returns:
    true if this RowSet object is read-Only and thus not updatable; false otherwise
    Throws:
    SQLException - if a database access error occurs or the given column number is out of bounds

method:isWritable(int) [NONE]

  • isWritable

    public boolean isWritable​(int columnIndex)
                       throws SQLException
    
    Indicates whether it is possible for a write operation on the designated column to succeed. A return value of true means that a write operation may or may not succeed.
    Specified by:
    isWritable in interface ResultSetMetaData
    Parameters:
    columnIndex - the first column is 1, the second is 2, and so on; must be between 1 and the number of columns, inclusive
    Returns:
    true if a write operation on the designated column may will succeed; false otherwise
    Throws:
    SQLException - if a database access error occurs or the given column number is out of bounds

method:isDefinitelyWritable(int) [NONE]

  • isDefinitelyWritable

    public boolean isDefinitelyWritable​(int columnIndex)
                                 throws SQLException
    
    Indicates whether a write operation on the designated column will definitely succeed.
    Specified by:
    isDefinitelyWritable in interface ResultSetMetaData
    Parameters:
    columnIndex - the first column is 1, the second is 2, and so on; must be between 1 and the number of columns, inclusive
    Returns:
    true if a write operation on the designated column will definitely succeed; false otherwise
    Throws:
    SQLException - if a database access error occurs or the given column number is out of bounds

method:getColumnClassName(int) [NONE]

  • getColumnClassName

    public String getColumnClassName​(int columnIndex)
                              throws SQLException
    
    Retrieves the fully-qualified name of the class in the Java programming language to which a value in the designated column will be mapped. For example, if the value is an int, the class name returned by this method will be java.lang.Integer.

    If the value in the designated column has a custom mapping, this method returns the name of the class that implements SQLData. When the method ResultSet.getObject is called to retrieve a value from the designated column, it will create an instance of this class or one of its subclasses.

    Specified by:
    getColumnClassName in interface ResultSetMetaData
    Parameters:
    columnIndex - the first column is 1, the second is 2, and so on; must be between 1 and the number of columns, inclusive
    Returns:
    the fully-qualified name of the class in the Java programming language that would be used by the method RowSet.getObject to retrieve the value in the specified column. This is the class name used for custom mapping when there is a custom mapping.
    Throws:
    SQLException - if a database access error occurs or the given column number is out of bounds

method:unwrap(java.lang.Class) [NONE]

  • unwrap

    public <T> T unwrap​(Class<T> iface)
                 throws SQLException
    
    Returns an object that implements the given interface to allow access to non-standard methods, or standard methods not exposed by the proxy. The result may be either the object found to implement the interface or a proxy for that object. If the receiver implements the interface then that is the object. If the receiver is a wrapper and the wrapped object implements the interface then that is the object. Otherwise the object is the result of calling unwrap recursively on the wrapped object. If the receiver is not a wrapper and does not implement the interface, then an SQLException is thrown.
    Specified by:
    unwrap in interface Wrapper
    Type Parameters:
    T - the type of the class modeled by this Class object
    Parameters:
    iface - A Class defining an interface that the result must implement.
    Returns:
    an object that implements the interface. May be a proxy for the actual implementing object.
    Throws:
    SQLException - If no object found that implements the interface

method:isWrapperFor(java.lang.Class) [NONE]

  • isWrapperFor

    public boolean isWrapperFor​(Class<?> interfaces)
                         throws SQLException
    
    Returns true if this either implements the interface argument or is directly or indirectly a wrapper for an object that does. Returns false otherwise. If this implements the interface then return true, else if this is a wrapper then return the result of recursively calling isWrapperFor on the wrapped object. If this does not implement the interface and is not a wrapper, return false. This method should be implemented as a low-cost operation compared to unwrap so that callers can use this method to avoid expensive unwrap calls that may fail. If this method returns true then calling unwrap with the same argument should succeed.
    Specified by:
    isWrapperFor in interface Wrapper
    Parameters:
    interfaces - a Class defining an interface.
    Returns:
    true if this implements the interface or directly or indirectly wraps an object that does.
    Throws:
    SQLException - if an error occurs while determining whether this is a wrapper for an object with the given interface.
    Since:
    1.6
