Parameters: type the type of the attribute.
Returns: the labels corresponding to this attribute, or null if this attribute is not a code attribute that contains labels.
Returns: true if the class of this object is equal to Attribute.
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.
Parameters: 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,
(int,char[]) 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.
Returns: a new Attribute object corresponding to the given bytes.
Parameters: 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.
Returns: the byte array form of this attribute.
