Method Detail
values
public static SourceVersion[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
for (SourceVersion c : SourceVersion.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
valueOf
public static SourceVersion valueOf(String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
- Parameters:
-
name
- the name of the enum constant to be returned. - Returns:
- the enum constant with the specified name
- Throws:
-
IllegalArgumentException
- if this enum type has no constant with the specified name -
NullPointerException
- if the argument is null
latest
public static SourceVersion latest()
Returns the latest source version that can be modeled.
- Returns:
- the latest source version that can be modeled
latestSupported
public static SourceVersion latestSupported()
Returns the latest source version fully supported by the current execution environment. RELEASE_5
or later must be returned.
- Returns:
- the latest source version that is fully supported
isIdentifier
public static boolean isIdentifier(CharSequence name)
Returns whether or not name
is a syntactically valid identifier (simple name) or keyword in the latest source version. The method returns true
if the name consists of an initial character for which Character.isJavaIdentifierStart(int)
returns true
, followed only by characters for which Character.isJavaIdentifierPart(int)
returns true
. This pattern matches regular identifiers, keywords, restricted keywords, and the literals "true"
, "false"
, "null"
, and "var"
. The method returns false
for all other strings.
- Parameters:
-
name
- the string to check - Returns:
-
true
if this string is a syntactically valid identifier or keyword,false
otherwise.
isName
public static boolean isName(CharSequence name)
Returns whether or not name
is a syntactically valid qualified name in the latest source version. Unlike isIdentifier
, this method returns false
for keywords, boolean literals, and the null literal. This method returns true
for restricted keywords and "var"
.
- Parameters:
-
name
- the string to check - Returns:
-
true
if this string is a syntactically valid name,false
otherwise.
isName
public static boolean isName(CharSequence name, SourceVersion version)
Returns whether or not name
is a syntactically valid qualified name in the given source version. Unlike isIdentifier
, this method returns false
for keywords, boolean literals, and the null literal. This method returns true
for restricted keywords and "var"
.
- Parameters:
-
name
- the string to check -
version
- the version to use - Returns:
-
true
if this string is a syntactically valid name,false
otherwise. - Since:
- 9
isKeyword
public static boolean isKeyword(CharSequence s)
Returns whether or not s
is a keyword, boolean literal, or null literal in the latest source version. This method returns false
for restricted keywords and "var"
.
- Parameters:
-
s
- the string to check - Returns:
-
true
ifs
is a keyword, or boolean literal, or null literal,false
otherwise.
isKeyword
public static boolean isKeyword(CharSequence s, SourceVersion version)
Returns whether or not s
is a keyword, boolean literal, or null literal in the given source version. This method returns false
for restricted keywords and "var"
.
- Parameters:
-
s
- the string to check -
version
- the version to use - Returns:
-
true
ifs
is a keyword, or boolean literal, or null literal,false
otherwise. - Since:
