Method Detail

isMathClass

public static boolean isMathClass(@SlashedClassName
                                  java.lang.String className)

assertIsDotted

@DottedClassName
public static java.lang.String assertIsDotted(@DottedClassName
                                              java.lang.String className)

assertIsSlashed

@SlashedClassName
public static java.lang.String assertIsSlashed(@SlashedClassName
                                               java.lang.String className)

toSignature

public static java.lang.String toSignature(@SlashedClassName
                                           java.lang.String className)

getPrimitiveType

@CheckForNull
public static java.lang.String getPrimitiveType(@SlashedClassName
                                                java.lang.String cls)

fromFieldSignature

@CheckForNull
@SlashedClassName
public static java.lang.String fromFieldSignature(java.lang.String signature)

Converts from signature to slashed class name (e.g., from Ljava/lang/String; to java/lang/String). Returns null if it is the signature for an array or primitive type.

toSlashedClassName

@SlashedClassName
public static java.lang.String toSlashedClassName(@SlashedClassName(when=UNKNOWN)
                                                  java.lang.String className)

Convert class name to slashed format. If the class name is already in slashed format, it is returned unmodified.

Parameters:

className - a class name

Returns:

the same class name in slashed format

toDottedClassName

@DottedClassName
public static java.lang.String toDottedClassName(@SlashedClassName(when=UNKNOWN)
                                                 java.lang.String className)

Convert class name to dotted format. If the class name is already in dotted format, it is returned unmodified.

Parameters:

className - a class name

Returns:

the same class name in dotted format

extractPackageName

@DottedClassName
public static java.lang.String extractPackageName(@DottedClassName
                                                  java.lang.String className)

extract the package name from a dotted class name. Package names are always in dotted format.

Parameters:

className - a dotted class name

Returns:

the name of the package containing the class

extractSimpleName

public static java.lang.String extractSimpleName(@DottedClassName
                                                 java.lang.String className)

isValidClassName

public static boolean isValidClassName(java.lang.String className)

Return whether or not the given class name is valid.

Parameters:

className - a possible class name

Returns:

true if it's a valid class name, false otherwise

isLocalOrAnonymous

public static boolean isLocalOrAnonymous(java.lang.String className)

Does a class name appear to designate an anonymous or local (defined inside method) class? Only the name is analyzed. No classes are loaded or looked up.

Parameters:

className - class name, slashed or dotted, fully qualified or unqualified

Returns:

true if className is the name of an anonymous or local class

isAnonymous

public static boolean isAnonymous(java.lang.String className)

Does a class name appear to designate an anonymous class? Only the name is analyzed. No classes are loaded or looked up.

Parameters:
