public ConvenientCodegen()

Method Detail

toPackageDefinition

public static java.lang.String toPackageDefinition(java.lang.String packageName)

Convert the package name into a valid package definition. If the package name is empty or null an empty string is returned. The package definition ends with a double new line if the package is valid.

Parameters:

packageName - name of the package

Returns:

package declaration

getSimpleClassName

public static java.lang.String getSimpleClassName(java.lang.Class c)

Retrieve the simple representation of a class

Parameters:

c - class to be represented

Returns:

last part of the full class name behind the '.'

getSimpleClassName

public static java.lang.String getSimpleClassName(java.lang.String c)

Retrieve the simple representation of a class

Parameters:

c - name of the class

Returns:

last part of the full class name behind the '.'

toName

public static java.lang.String toName(java.lang.String name,
                                      java.lang.String delimiter)

Take a name and convert it to a convenient java name. The name may be divided into several parts by a delimiter.

The input string 'USER_NAME' with the delimiter '_' becomes 'userName'.
The input string 'get_USER_NAME' with the delimiter '_' becomes 'getUserName'.

Parameters:

name - to be converted

delimiter - string or null

Returns:

converted variable name

isPrimitiveClass

public static boolean isPrimitiveClass(java.lang.String c)

Check whether the class belongs to the java.lang package

Parameters:

c - name of the class

Returns:

true if the class resides in java.lang

isPrimitiveClass

public static boolean isPrimitiveClass(java.lang.Class c)

Check whether the class belongs to the java.lang package

Parameters:

c - class to be checked

Returns:

true if the class resides in java.lang

camelCase

public static java.lang.String camelCase(java.lang.String s,
                                         java.lang.String delimiter)

Camel-case a string that is divided by the designated delimiter

Parameters:

s - input string

delimiter - parting the words in the string

Returns:

camel-cased string

camelCaseLowerCaseFirst

public static java.lang.String camelCaseLowerCaseFirst(java.lang.String s,
                                                       java.lang.String delimiter)

Camale-case a string that is divided by the designated delimiter with a lower case start.

Parameters:

s - input string

delimiter - parting the words in the string

Returns:

camel-cased string

toLowerCaseFirst

public static java.lang.String toUpperCaseFirst(java.lang.String s)

Make the first letter of a string upper case

Parameters:

s - input String

Returns:

input-String with a upper-case first letter

getClassShortName

public static java.lang.String getClassShortName(DataBaseTableField dbtf)

Extract the class name from the class declaration

Parameters:

dbtf - Field declaration

Returns:

name of the class

isPrimitiveType

public static boolean isPrimitiveType(DataBaseTableField dbtf)

Check weather the type is a primitive type, meaning a type defined in the package java.lang

Parameters:

dbtf - Field to be checked

Returns:

true if the type is primitive

isBoxingType

public static boolean isBoxingType(java.lang.Class type)
