Method Detail

getJavaType

public static String getJavaType(ColumnSpec column,
                                 boolean fullyQualified)
                          throws CmpGeneratorException

Finds the appropriate type mapping from a given column spec. Note that the type returned here is the "simple" type as it is stored in the database, not the "complex" type.

Parameters:

column - the column specification

fullyQualified - whether the type should contain the package name or not

Returns:

the simple java type used to store the column in the db

Throws:

CmpGeneratorException - if no type mapping can be found

unqualifyType

public static String unqualifyType(String typeName)

Returns everything after the last dot in a type name.

Parameters:

typeName - a java type name

Returns:

the unqualified type name, or the argument if it was not a qualified java type name

getTypeMapping

public static String getTypeMapping(String sqlType)

Returns the fully qualified java type to which an SQL type is mapped.

Parameters:

sqlType - the name of the sql type

Returns:

the FQ type name of the java type, or null if this method can not find a type mapping

getNumberTypeMapping

public static String getNumberTypeMapping(String sqlType,
                                          int precision,
                                          int scale)

Returns a type mapping for numeric types.

Parameters:

sqlType - the name of the sql type

precision - the precision of the sql type

scale - the scale of the sql type, or 0 if no scale given

Returns:

the name of the appropriate java type

isPrimitiveType

public static boolean isPrimitiveType(String type)

Determines whether a given type is primitive.

Parameters:

type - the name of a java type

Returns:

true if the type is primitive, false otherwise

primitiveToObject

public static String primitiveToObject(String primitiveType)

Maps a java primitive type to its corresponding wrapper object.

Parameters:

primitiveType - the name of a primitive type

Returns:

the corresponding wrapper object

Throws:

IllegalArgumentException - if primitiveType is not a primitive type
