接口 IInterfaceCollection

所有超级接口:

Cloneable, IClassFormatOutput

public interface IInterfaceCollection
extends Cloneable, IClassFormatOutput

An abstraction of the 'interfaces' component of .class format. The contents are constant pool indices of CONSTANT_Class_info structures corresponding to direct superinterfaces of this class/interface. The order in which they appear is the left-to-right order of their declaration in the implements/extends clause.

方法详细资料

get

int get(int offset)

Returns the CONSTANT_Class_info constant pool index for offset'th direct superinterface.

参数:

offset - superinterface number [must be in [0, size()) range]

返回:

constant pool index [always positive]

抛出:

IndexOutOfBoundsException - if 'offset' is outside of valid range

size

int size()

Returns the number of direct superinterfaces for this class/interface.

返回:

int number of direct superinterfaces [can be 0]

clone

Object clone()

accept

void accept(IClassDefVisitor visitor,
            Object ctx)

add

int add(int interface_index)

Appends a new superinterface pointer to the collection. No duplicate checks are made.

参数:

interface_index - constant pool index [must be positive; input not validated]

返回:

offset of the new pointer [same as size()-1 when called after this method]

set

int set(int offset,
        int interface_index)

Replaces superinterface pointer number 'offset' with new value 'interface_index'. No duplicate checks are made. It is the responsibility of the caller to ensure that the relevant CONSTANT_Class_info descriptor will be found in the constant pool, in the slot pointed to by 'interface_index'.

参数:

offset - offset of the superinterface pointer to replace [must be in [0, size()) range]

interface_index - constant pool index [must be positive; input not validated]

返回:

previous value at the given index [always positive]

抛出:

IndexOutOfBoundsException - if 'offset' is outside of valid range
