String org.objectweb.jonas_ejb.lib.JavaType.getName (  Class  c  )  [static]

Returns the name of the given type Definition at line 72 of file JavaType.java.

String org.objectweb.jonas_ejb.lib.JavaType.getSQLGetMethod (  Class  c  )  [static]

Returns the name of the getXXX method associated with the given type in java.sql.ResultSet. Parameters: c  the class object for a Java type. Returns: a string representing the name of the get method, null in error case Definition at line 123 of file JavaType.java.

String org.objectweb.jonas_ejb.lib.JavaType.getSQLSetMethod (  Class  c  )  [static]

Returns the name of the setXXX method associated with the given type in java.sql.ResultSet. Parameters: c  the class object for a Java type. Returns: a string representing the name of the set method, null in error case Definition at line 133 of file JavaType.java.

String org.objectweb.jonas_ejb.lib.JavaType.getSQLType (  Class  c  )  [static]

Returns the SQL Type mapping the given Java Type. Parameters: c  the class object for a Java type. Returns: the SQL Type mapping the given Java Type, (Types.OTHER in error case) Definition at line 149 of file JavaType.java.

boolean org.objectweb.jonas_ejb.lib.JavaType.isCollecOrEnum (  Class  c  )  [static]

Returns true if the given class implements java.uti.Collection or java.util.Enumeration false otherwise. Definition at line 113 of file JavaType.java.

boolean org.objectweb.jonas_ejb.lib.JavaType.isSerializable (  Class  c  )  [static]

Returns true if the given class is a Serializable Java Type, false otherwise. Definition at line 87 of file JavaType.java.

boolean org.objectweb.jonas_ejb.lib.JavaType.isValidForRmi (  Class  c  )  [static]

Returns true if the given class is a valid type for RMI, false otherwise. Valid types for RMI are primitive types, remote objects, and non-remote objects that implement the java.io.Serializable interface Definition at line 105 of file JavaType.java.

boolean org.objectweb.jonas_ejb.lib.JavaType.isVoid (  Class  c  )  [static]

Returns true if the given type is the type 'void' Definition at line 65 of file JavaType.java.

boolean org.objectweb.jonas_ejb.lib.JavaType.isXxxObjectMethod (  String  name  )  [static]

Returns true if the given method name is getObject() or setObject() Definition at line 140 of file JavaType.java.

String org.objectweb.jonas_ejb.lib.JavaType.toStringObject (  String  name, Class  c )  [static]

If it is a primitive type, return a new Object constructor, else return the same object. There are nine predefined Class objects to represent the eight primitive types and void. These are created by the Java Virtual Machine, and have the same names as the primitive types that they represent, namely boolean, byte, char, short, int, long, float, and double. Parameters: name  name of the var val  the object value Returns: new object Definition at line 210 of file JavaType.java.
