compact

public static final String compact(String name)

Remove repeating strings that are appearing in the name. This is done by splitting words (camel case) and using each word once.

Parameters:

Returns:

The compact name.

prefixKeywords

public static final String prefixKeywords(String name)

Adds an underscore to the specified String, if its a Java Keyword.

toFieldName

public static final String toFieldName(String name)

Converts the string into a safe field name.

Parameters:

name - The field name.

Returns:

The safe field name.

camelCase

public static final String camelCase(String name)

Converts the given string to camelCase format.

This method takes a string input and converts it to camelCase format, where each word in the input string is capitalized (except the first word) and concatenated together without spaces. Non-alphanumeric characters are treated as word separators.

If the input string is null, null is returned. If the input string is empty or contains only non-alphanumeric characters, an empty string is returned.

For example:

 camelCase("helloWorld") returns "helloWorld"
 camelCase("hello_world") returns "helloWorld"
 camelCase("hello world") returns "helloWorld"
 camelCase("foo-bar-baz") returns "fooBarBaz"
 camelCase("123_456_789") returns "123456789"
 camelCase("   ") returns ""
 camelCase(null) returns null
 

Parameters:

name - the string to convert to camelCase

Returns:

the input string converted to camelCase format, or null if the input string is null, or an empty string if the input string is empty or contains only non-alphanumeric characters

toPojoName

public static final String toPojoName(String name,
                                      String prefix,
                                      String suffix)

Converts a name of an interface or abstract class to Pojo name. Remove leading "I" and "Abstract" or trailing "Interface".

Parameters:

name - The name to convert.

prefix - The prefix to use if needed.

suffix - The suffix to user if needed.

Returns:

The converted name, if a conversion actually happened or the original name prefixed and suffixed otherwise.
