Method Detail

checkJavaIdentifier

public static void checkJavaIdentifier(java.lang.String pName)

Returns whether the given name is a valid Java identifier. Works by using Character.isJavaIdentifierStart(char) and Character.isJavaIdentifierPart(char).

Throws:

java.lang.IllegalArgumentException - The name is not valid. An explanation why is given in the detail message.

asJavaIdentifier

public static java.lang.String asJavaIdentifier(java.lang.String pIdentifier)

Takes as input an arbitrary String and maps it to a String, which is a valid Java identifier. Mapping works as follows:

1. For the first character, invokes Character.isJavaIdentifierStart(char). If that method returns false, replaces the character with an underscore ('_').
2. For any following character, invokes Character.isJavaIdentifierPart(char). If that method returns false, replaces the character with an underscore ('_').

Parameters:

pIdentifier - The identifier being mapped

Throws:

java.lang.IllegalArgumentException - The parameter pIdentifier cannot be converted into a Java identifier, because it is null or empty.
