Method Detail

classForName
public static Class classForName(String className) throws ClassNotFoundException(Code)
	Returns the class that matches the supplied names. N.B. The class name must be specified in Java source form, not the JVM runtime form (which uses non-reversible names for primitive types and somewhat obfuscated names for array types). Parameters: className - Class name. Class for supplied name. throws: ClassNotFoundException -

classesForNames
public static Class[] classesForNames(String[] classNames) throws ClassNotFoundException(Code)
	Returns an array of classes to match the supplied names. N.B. Class names must be specified in Java source form, not the JVM runtime form (which uses non-reversible names for primitive types and somewhat obfuscated names for array types). Parameters: classNames - Class names. Classes for supplied names or `null` if`classNames` is `null`. throws: ClassNotFoundException -

findMethod
public static Method findMethod(String className, String methodSig) throws ClassNotFoundException, NoSuchMethodException(Code)
	Returns the method that matches a specified signature. Parameters: className - The class that defines the method. Parameters: methodSig - The method signature in standard Java source form. The Method object. throws: ClassNotFoundException - If the class could be loaded. throws: NoSuchMethodException - If no matching method was found.

getPropertyNames
public static String[] getPropertyNames(PropertyDescriptor[] propDescs)(Code)

introspect
public static PropertyDescriptor[] introspect(Class beanClass, Class stopClass)(Code)
	Introspects properties of the specified class(es) into a map. Parameters: beanClass - Parameters: stopClass - Array of `PropertyDescriptor`.

namesForClasses
public static String[] namesForClasses(Class[] parmTypes)(Code)
	Converts an array of classes to an array of class names. Parameters: parmTypes - Array of classes. A corresponding array of class names in Java source format.

signatureFromMethod
public static String signatureFromMethod(Method method)(Code)
	Generates a string method description from a Method object. Parameters: method - Method object. String representation of the method in JVM runtime format.

signatureFromMethod
public static String signatureFromMethod(Method method, boolean includeModifiers, boolean includeReturn, boolean includeClass, boolean includeMethod, boolean includeParameterTypes, boolean includeExceptions)(Code)
	Generates a string method description from a Method object. Parameters: method - Method object. Parameters: includeModifiers - `true` to include the modifiers. Parameters: includeReturn - `true` to include the return type. Parameters: includeClass - `true` to include the class name. Parameters: includeMethod - `true` to include the method name. Parameters: includeParameterTypes - `true` to include the parameters. Parameters: includeExceptions - `true` to include the exceptions. String representation of the method in JVM runtime format.
