 Object obj,
 Object[] args)
              throws InvocationTargetException

Throws:

InvocationTargetException

newInstance

public Object newInstance()
                   throws InvocationTargetException

Throws:

InvocationTargetException

newInstance

public Object newInstance(Class[] parameterTypes,

getMethod

public FastMethod getMethod(Method method)

getConstructor

public FastConstructor getConstructor(Constructor constructor)

getMethod

public FastMethod getMethod(String name,
 Class[] parameterTypes)

getConstructor

public FastConstructor getConstructor(Class[] parameterTypes)

getName

public String getName()

getJavaClass

public Class getJavaClass()

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

getIndex

public abstract int getIndex(String name,
 Class[] parameterTypes)

Return the index of the matching method. The index may be used later to invoke the method with less overhead. If more than one method matches (i.e. they differ by return type only), one is chosen arbitrarily.

Parameters:

name - the method name

parameterTypes - the parameter array

Returns:

the index, or -1 if none is found.

See Also:

• invoke(int, Object, Object[])

getIndex

public abstract int getIndex(Class[] parameterTypes)

Return the index of the matching constructor. The index may be used later to create a new instance with less overhead.

Parameters:

parameterTypes - the parameter array

Returns:

the constructor index, or -1 if none is found.

See Also:

• newInstance(int, Object[])

invoke

public abstract Object invoke(int index,
 Object obj,
 Object[] args)
                       throws InvocationTargetException

Invoke the method with the specified index.

Parameters:

index - the method index

obj - the object the underlying method is invoked from

args - the arguments used for the method call

Throws:

InvocationTargetException - if the underlying method throws an exception

See Also:

• getIndex(java.lang.String,java.lang.Class[])

newInstance

public abstract Object newInstance(int index,
 Object[] args)
                            throws InvocationTargetException

Create a new instance using the specified constructor index and arguments.

Parameters:

index - the constructor index

args - the arguments passed to the constructor

Throws:

InvocationTargetException - if the constructor throws an exception

See Also:

• getIndex(java.lang.Class[])

getIndex

public abstract int getIndex(Signature sig)

getMaxIndex

public abstract int getMaxIndex()

Returns the maximum method index for this class.

getSignatureWithoutReturnType

protected static String getSignatureWithoutReturnType(String name,
 Class[] parameterTypes)
