Method Detail

descriptorStringToParameterArray

public static java.lang.String[] descriptorStringToParameterArray(java.lang.String methodDescriptor)

returns an array of String representations of the parameter types. Primitives are returned as their native representations, while classes are returned in the internal descriptor form e.g. Ljava/lang/Integer;

classToStringRepresentation

public static java.lang.String classToStringRepresentation(java.lang.Class<?> c)

isPrimitive

public static boolean isPrimitive(java.lang.String descriptor)

returns true if the descriptor represents a primitive type

isWide

public static boolean isWide(java.lang.String descriptor)

returns true if the descriptor represents a long or a double

isWide

public static boolean isWide(java.lang.Class<?> cls)

returns true if the class represents a long or a double

getConstructorDescriptor

public static java.lang.String getConstructorDescriptor(java.lang.reflect.Constructor<?> c)

getParameterTypes

public static java.lang.String[] getParameterTypes(java.lang.reflect.Method m)

getParameterTypes

public static java.lang.String[] getParameterTypes(java.lang.Class<?>[] parameters)

getMethodDescriptor

public static java.lang.String getMethodDescriptor(java.lang.reflect.Method m)

getMethodDescriptor

public static java.lang.String getMethodDescriptor(java.lang.String[] parameters,
                                   java.lang.String returnType)
