Method Detail

setJavaTypeConversionIgnoreList

public void setJavaTypeConversionIgnoreList(String commaSeparatedIgnoreList)

Specifies a list of one or more fully qualified java types that should be ignored whenever a type conversion is done. See Spring namespace property "javaTypeConversionIgnoreList"

Parameters:

commaSeparatedIgnoreList - comma separated list of types to be ignored

typeConvert

public String typeConvert(String sourceType,
                 String sourceValue,
                 String targetType)

Attempts to code a type conversion from the specified source value to the target type that can be used on the right hand side of an assignment. If such a conversion exists, the Java code fragment to do that will be returned. If no such conversion exists, null is returned.

Parameters:

sourceType - The fully qualified data type of the source value

sourceValue - The actual source value (usually a variable name)

targetType - The fully qualified data type of the target value

Returns:

The converted value, or null if no conversion can be done.

getJavaLangTypeName

public static String getJavaLangTypeName(String name)

Creates a java.lang. fully qualified name from the given name, inserting 'java.lang.' in front if needed. Many EJB3 and Hibernate configuration files require java.lang. in the type name, where Java code does not (gives compiler warning). This allows UML Primitive types to be modeled and mapped without java.lang. implementation.

Parameters:

name - the name of the model element.

Returns:

the java.lang. fully qualified name, if needed.
