Method Detail

getTypeCategory

public static final GenericUtilities.TypeCategory getTypeCategory(org.apache.bcel.generic.Type type)

Get the TypeCategory that represents this Object

GenericUtilities.TypeCategory

isPlainObject

public static final boolean isPlainObject(org.apache.bcel.generic.Type type)

getString

public static final java.lang.String getString(org.apache.bcel.generic.Type type)

Get String representation of a Type including Generic information

getType

public static GenericObjectType getType(java.lang.String className,
                                        java.util.List<? extends org.apache.bcel.generic.ReferenceType> parameters)

getType

@CheckForNull
public static org.apache.bcel.generic.Type getType(java.lang.String signature)

This method is analogous to Type.getType(String), except that it also accepts signatures with generic information. e.g. Ljava/util/ArrayList<TT;>;

The signature should only contain one type. Use GenericSignatureParser to break up a signature with many types or call createTypes(String) to return a list of types

merge

public static org.apache.bcel.generic.ObjectType merge(@CheckForNull
                                                       org.apache.bcel.generic.Type t1,
                                                       org.apache.bcel.generic.ObjectType t2)

merge

public static org.apache.bcel.generic.Type merge(@CheckForNull
                                                 GenericObjectType t1,
                                                 org.apache.bcel.generic.Type t2)

merge

public static org.apache.bcel.generic.ObjectType merge(@CheckForNull
                                                       GenericObjectType t1,
                                                       org.apache.bcel.generic.ObjectType t2)

removeMatchedAngleBrackets

public static java.lang.String removeMatchedAngleBrackets(java.lang.String s)

nextUnmatchedRightAngleBracket

public static int nextUnmatchedRightAngleBracket(java.lang.String s,
                                                 int startingAt)

lastMatchedLeftAngleBracket

public static int lastMatchedLeftAngleBracket(java.lang.String s)

getTypeParameters

@CheckForNull
public static final java.util.List<org.apache.bcel.generic.ReferenceType> getTypeParameters(java.lang.String signature)

Parse a bytecode signature that has 1 or more (possibly generic) types and return a list of the Types.

Parameters:

signature - bytecode signature e.g. e.g. Ljava/util/ArrayList<Ljava/lang/String;>;Ljava/util/ArrayList<TT;>;Ljava/util/ArrayList<*>;

split

public static final java.util.List<java.lang.String> split(java.lang.String signature,
                                                           boolean skipInitialAngleBracket)
