All Implemented Interfaces:

Serializable, DefaultAccessorNamingStrategy.BaseNameValidator

Enclosing class:

DefaultAccessorNamingStrategy

public static class DefaultAccessorNamingStrategy.FirstCharBasedValidator
extends Object
implements DefaultAccessorNamingStrategy.BaseNameValidator, Serializable

Simple implementation of DefaultAccessorNamingStrategy.BaseNameValidator that checks the first character and nothing else if (and only if!) prefix is empty (so offset passed is NOT zero).

Instances are to be constructed using method forFirstNameRule(boolean, boolean).

Method Details

forFirstNameRule

public static DefaultAccessorNamingStrategy.BaseNameValidator forFirstNameRule(boolean allowLowerCaseFirstChar,
 boolean allowNonLetterFirstChar)

Factory method to use for getting an instance with specified first-character restrictions, if any; or null if no checking is needed.

Parameters:

allowLowerCaseFirstChar - Whether base names that start with lower-case letter (like "a" or "b") are accepted as valid or not: consider difference between "setter-methods" setValue() and setvalue().

allowNonLetterFirstChar - Whether base names that start with non-letter character (like "_" or number 1) are accepted as valid or not: consider difference between "setter-methods" setValue() and set_value().

Returns:

Validator instance to use, if any; null to indicate no additional rules applied (case when both arguments are true)

accept

public boolean accept(char firstChar,
 String basename,
 int offset)

Description copied from interface: DefaultAccessorNamingStrategy.BaseNameValidator

Method called to check whether given base name is acceptable: called for accessor method name after removing prefix. NOTE: called even if "prefix" is empy (i.e. nothing really removed)

Specified by:

accept in interface DefaultAccessorNamingStrategy.BaseNameValidator

Parameters:

firstChar - First character of the base name

basename - Full base name (after removing prefix)

offset - Length of prefix removed

Returns:

true if base name is acceptable; false otherwise
