Class EnclosingMethodAttribute
public class EnclosingMethodAttribute
The EnclosingMethod attribute is an optional fixed-length attribute in
the attributes table of the ClassFile structure. A class must have an
EnclosingMethod attribute if and only if it is a local class or an
anonymous class. A class may have no more than one EnclosingMethod attribute.
The EnclosingMethod attribute has the following format:
EnclosingMethod_attribute {
u2 attribute_name_index;
u4 attribute_length;
u2 class_index
u2 method_index;
}
The items of the EnclosingMethod_attribute structure are as follows:
EnclosingMethodAttribute
public EnclosingMethodAttribute()
EnclosingMethodAttribute
public EnclosingMethodAttribute(String owner,
String name,
String desc)
read
protected Attribute read(ClassReader cr,
int off,
int len,
char[] buf,
int codeOff,
Label[] labels)
Reads a
type
attribute. This method must return a
new
Attribute
object, of type
type
, corresponding to the
len bytes starting at the given offset, in the given class reader.
- read in interface Attribute
cr
- the class that contains the attribute to be read.off
- index of the first byte of the attribute's content in cr.b
. The 6 attribute header bytes, containing the type
and the length of the attribute, are not taken into account here.len
- the length of the attribute's content.buf
- buffer to be used to call readUTF8
,
readClass
or readConst
.codeOff
- index of the first byte of code's attribute content in
cr.b
, or -1 if the attribute to be read is not a
code attribute. The 6 attribute header bytes, containing the type and
the length of the attribute, are not taken into account here.labels
- the labels of the method's code, or null if the
attribute to be read is not a code attribute.
- a new
Attribute
object corresponding to the given
bytes.
toString
public String toString()
write
protected ByteVector write(ClassWriter cw,
byte[] code,
int len,
int maxStack,
int maxLocals)
Returns the byte array form of this attribute.
- write in interface Attribute
cw
- the class to which this attribute must be added. This parameter
can be used to add to the constant pool of this class the items that
corresponds to this attribute.code
- the bytecode of the method corresponding to this code
attribute, or null if this attribute is not a code
attributes.len
- the length of the bytecode of the method corresponding to this
code attribute, or null if this attribute is not a code
attribute.maxStack
- the maximum stack size of the method corresponding to this
code attribute, or -1 if this attribute is not a code attribute.maxLocals
- the maximum number of local variables of the method
corresponding to this code attribute, or -1 if this attribute is not
a code attribute.
- the byte array form of this attribute.
