public final class ClassUtil
extends java.lang.Object

Method Summary

static boolean	directlyImplements(java.lang.Class<?> cls, java.lang.Class<?> interfaceType)
static java.lang.Class<?>	implementingClassOrNull(java.lang.Class<?> classCandidate, java.lang.Class<?> requiredClass, java.lang.Class<?> constructorParamType) Returns the supplied Class so long as it implements (or is a subclass of) the required class, and also has either a constructor accepting the specified param type, or has a no-arg constructor.
static java.lang.Class<?>	implementingClassOrNull(java.lang.String classCandidateName, java.lang.Class<?> requiredClass, java.lang.Class<?> constructorParamType)
static java.lang.Object	newInstance(java.lang.Class<?> type, java.lang.Class<?>[] constructorParamTypes, java.lang.Object[] constructorArgs) Tries to instantiate using a constructor accepting the supplied arguments; if no such constructor then falls back to trying the no-arg constructor.
static java.lang.Object	newInstance(java.lang.Class<?> type, java.lang.Class<?> constructorParamType, java.lang.Object constructorArg)

Method Detail

newInstance

public static java.lang.Object newInstance(java.lang.Class<?> type,
                                           java.lang.Class<?> constructorParamType,
                                           java.lang.Object constructorArg)

newInstance

public static java.lang.Object newInstance(java.lang.Class<?> type,
                                           java.lang.Class<?>[] constructorParamTypes,
                                           java.lang.Object[] constructorArgs)

implementingClassOrNull

public static java.lang.Class<?> implementingClassOrNull(java.lang.Class<?> classCandidate,
                                                         java.lang.Class<?> requiredClass,

Returns the supplied Class so long as it implements (or is a subclass of) the required class, and also has either a constructor accepting the specified param type, or has a no-arg constructor.

implementingClassOrNull

public static java.lang.Class<?> implementingClassOrNull(java.lang.String classCandidateName,
                                                         java.lang.Class<?> requiredClass,
