Method Detail

getResultSetMetaClass

public static MetaClass getResultSetMetaClass(java.lang.Class type,
                                              MetaClassRegistry classRegistry)

Returns the appropriate meta-class for the specified Java class. If an appropriate meta-class has not been registered then this method returns null.

Parameters:

type - Class to look for meta-class for.

classRegistry - Meta-class registry to search.

getResultSetMetaClass

public static MetaClass getResultSetMetaClass(java.lang.Class type)

Returns the appropriate meta-class for the specified Java class searching in the context class registry. If an appropriate meta-class has not been registered then this method returns null.

Parameters:

type - Class to look for meta-class for.

getResultSetPropertyInfos

public static java.util.List getResultSetPropertyInfos(MetaClassRegistry classRegistry,
                                                       java.sql.ResultSet resultSet,
                                                       boolean resolveTypes)
                                                throws java.sql.SQLException

Retrieves the list of property infor objects for the specified ResultSet by examining the set's meta-data.

Parameters:

classRegistry - Meta-class registry to use for resolving dependent types.

resultSet - Result set to generate property list for.

resolveTypes - Flag to indicate if type resolution should be deferred (if false).

Returns:

List of PropertyInfo objects for the columns in the result set.

Throws:

java.sql.SQLException - If there is a problem retrieved the result set's meta data.

getResultSetPropertyInfos

public static java.util.List getResultSetPropertyInfos(MetaClassRegistry classRegistry,
                                                       java.sql.ResultSet resultSet)
                                                throws java.sql.SQLException

Retrieves the list of property infor objects for the specified ResultSet by examining the set's meta-data. Normal property types will be marked deferred and resolved at a later time.

Parameters:

classRegistry - Meta-class registry to use for resolving dependent types.

resultSet - Result set to generate property list for.

Returns:

List of PropertyInfo objects for the columns in the result set.

Throws:

java.sql.SQLException - If there is a problem retrieved the result set's meta data.

getResultSetPropertyInfos

public static java.util.List getResultSetPropertyInfos(java.sql.ResultSet resultSet)
                                                throws java.sql.SQLException

Retrieves the list of property infor objects for the specified ResultSet by examining the set's meta-data. And dependent meta-class lookups are done using the context class registry. Normal property types will be marked deferred and resolved at a later time.

Parameters:

resultSet - Result set to generate property list for.

Returns:

List of PropertyInfo objects for the columns in the result set.

Throws:

java.sql.SQLException - If there is a problem retrieved the result set's meta data.

getResultSetPropertyInfos

public static java.util.List getResultSetPropertyInfos(java.sql.ResultSet resultSet,
                                                       boolean resolveTypes)
                                                throws java.sql.SQLException

Retrieves the list of property infor objects for the specified ResultSet by examining the set's meta-data. And dependent meta-class lookups are done using the context class registry.

Parameters:

resultSet - Result set to generate property list for.

resolveTypes - Flag to indicate if type resolution should be deferred (if false).

Returns:

List of PropertyInfo objects for the columns in the result set.

Throws:

java.sql.SQLException - If there is a problem retrieved the result set's meta data.
