Method Details

generateCodeImports

public static void generateCodeImports(StringBuilder code)

Generates the import statement required before the class definition

Parameters:

code -

generateCodeStandalone

public String generateCodeStandalone(String name,
 Function<String,ParameterType> inputParameterTypes)
                              throws ParseException

Generate code that can be used in a java compilation unit

Parameters:

name - - the name of the output parameter

inputParameterTypes - - function that gives the types for the input parameters; the function should return null if the parameter is unknown (a ParseException will be thrown in this case).

Returns:

a piece of java code ready to be compiled

Throws:

ParseException

generateCode

public void generateCode(String name,
 StringBuilder sb,
 Function<String,ParameterType> inputParameterTypes)
                  throws ParseException

Appends the class definition to the StringBuilder (which needs to have on top the package and import declaration). Can be used to generate multiple classes in the same unit.

Parameters:

name -

sb -

Throws:

ParseException
