get

public final Attribute_info get(int offset)

Description copied from interface: IAttributeCollection

Returns the attribute descriptor at a given offset.

Specified by:

get in interface IAttributeCollection

Parameters:

offset - attribute offset [must be in [0, size()) range; input not checked]

Returns:

Attribute_info descriptor [never null]

hasSynthetic

public final boolean hasSynthetic()

Specified by:

hasSynthetic in interface IAttributeCollection

hasBridge

public final boolean hasBridge()

Specified by:

hasBridge in interface IAttributeCollection

getInnerClassesAttribute

public final InnerClassesAttribute_info getInnerClassesAttribute()

Specified by:

getInnerClassesAttribute in interface IAttributeCollection

size

public final int size()

Description copied from interface: IAttributeCollection

Returns the number of attributes in this collection [can be 0].

Specified by:

size in interface IAttributeCollection

length

public final long length()

Description copied from interface: IAttributeCollection

Returns the total length of this collection when converted to .class format [including 2 count bytes]

Specified by:

length in interface IAttributeCollection

clone

public java.lang.Object clone()

Performs a deep copy.

Specified by:

clone in interface IAttributeCollection

Overrides:

clone in class java.lang.Object

writeInClassFormat

public void writeInClassFormat(UDataOutputStream out)
                        throws java.io.IOException

Specified by:

writeInClassFormat in interface IClassFormatOutput

Throws:

java.io.IOException

accept

public void accept(IClassDefVisitor visitor,
          java.lang.Object ctx)

Specified by:

accept in interface IAttributeCollection

add

public int add(Attribute_info attribute)

Description copied from interface: IAttributeCollection

Adds a new Attribute_info descriptor to this collection. No duplicate checks are made. It is the responsibility of the caller to ensure that all data referenced in 'attribute' will eventually appear in the constant pool.

Specified by:

add in interface IAttributeCollection

Parameters:

attribute - new attribute descriptor [may not be null]

set

public Attribute_info set(int offset,
                 Attribute_info attribute)

Description copied from interface: IAttributeCollection

Replaces the Attribute_info descriptor at a given offset. No duplicate checks are made. It is the responsibility of the caller to ensure that all data referenced in 'attribute' will eventually appear in the constant pool.

Specified by:

set in interface IAttributeCollection

Parameters:

offset - attribute offset [must be in [0, size()) range; input not checked]

attribute - new attribute descriptor [may not be null]

Returns:

previous attribute descriptor at this offset [never null]

remove

public Attribute_info remove(int offset)

Description copied from interface: IAttributeCollection

Removes the Attribute_info descriptor at a given offset.

Specified by:

remove in interface IAttributeCollection

Parameters:

offset - attribute offset [must be in [0, size()) range; input not checked]

Returns:

current attribute descriptor at this offset [never null]
