Constructor Detail ClassMetaData public ClassMetaData()(Code) Constructs a new ClassMetaData object with an empty class name. ClassMetaData public ClassMetaData(String classname)(Code) Constructs a new ClassMetaData object with the specified class name. Parameters:   classname - The fully-qualified classname of the class this meta object is to represent. Method Detail addAttribute public void addAttribute(String attName, String type)(Code) Add an attribute to this meta data object. Parameters:   attName - The attribute to be added. Parameters:   type - The Java type of the attribute to be added. addKeyField public void addKeyField(String attName, String type, boolean autogen)(Code) Add a primary key field attribute to this meta data object. Parameters:   attName - The name of the primary key attribute to be added. Parameters:   type - The Java type of the primary key attribute. Parameters:   autogen - Indicates if the key will be auto-generated. addMember public void addMember(String attName, String memberName)(Code) Add a member for an attribute to this meta object. Parameters:   attName - The name of the attribute for which the member is to be added. Parameters:   memberName - The name of the member variable. addSqlName public void addSqlName(String attName, String sqlName)(Code) Add a new sql name for an attribute to this meta object. Parameters:   attName - The name of the attribute for which the sql name is to be added. Parameters:   sqlName - The sql name of the attribute. addSqlType public void addSqlType(String attName, String type)(Code) Add sql type data for a particular attribute in this meta data object. Parameters:   attName - The name of the attribute for which sql type is to be added. Parameters:   type - The sql type for the attribute. getAccessor public AccessibleObject getAccessor(String attributeName)(Code) Returns the accessor Field/Method for the specified attribute. Parameters:   attributeName - Name of the attribute for which accessor is required. The accessor Field/Method for the attribute. getAccessors public Map getAccessors()(Code) Return a Map of the accessor Field/Method objects for the defined class where key is the name of the attribute and value is the accessor Field/Method object. A Map of the accessor Field/Method objects for the defined class. getAllKeyFieldNames public Map getAllKeyFieldNames()(Code) Returns a Map where key is the name of a primary key attribute for the class and value is its corresponding Java type. Since 1.3 - This include both manual and auto genrated key fields, use getNonAutoKeyFieldNames() to get just the manual key fields.
