 public static boolean isIdentifier(CharSequence name) {
String id = name.toString();
if (id.length() == 0) {
return false;
}
int cp = id.codePointAt(0);
if (!Character.isJavaIdentifierStart(cp)) {
return false;
}
for (int i = Character.charCount(cp);
i < id.length();
i += Character.charCount(cp)) {
cp = id.codePointAt(i);
if (!Character.isJavaIdentifierPart(cp)) {
return false;
}
}
return true;
}
Returns whether or not {@code name} is a syntactically valid
identifier (simple name) or keyword in the latest source
version. The method returns {@code true} if the name consists
of an initial character for which Character#isJavaIdentifierStart(int) returns {@code true},
followed only by characters for which Character#isJavaIdentifierPart(int) returns {@code true}.
This pattern matches regular identifiers, keywords, and the
literals {@code "true"}, {@code "false"}, and {@code "null"}.
The method returns {@code false} for all other strings. |
public static boolean isKeyword(CharSequence s) {
String keywordOrLiteral = s.toString();
return keywords.contains(keywordOrLiteral);
} Returns whether or not {@code s} is a keyword or literal in the
latest source version. |
public static boolean isName(CharSequence name) {
String id = name.toString();
for(String s : id.split("\\.", -1)) {
if (!isIdentifier(s) || isKeyword(s))
return false;
}
return true;
} Returns whether or not {@code name} is a syntactically valid
qualified name in the latest source version. Unlike isIdentifier , this method returns {@code false}
for keywords and literals. |
public static SourceVersion latest() {
return RELEASE_7;
} Returns the latest source version that can be modeled. |
public static SourceVersion latestSupported() {
return latestSupported;
} Returns the latest source version fully supported by the
current execution environment. {@code RELEASE_5} or later must
be returned. |
