Package org.apache.bcel.classfile
Class Unknown
java.lang.Object
org.apache.bcel.classfile.Attribute
org.apache.bcel.classfile.Unknown
This class represents a reference to an unknown (i.e., application-specific) attribute of a class. It is instantiated
from the
Attribute.readAttribute(java.io.DataInput, ConstantPool) method. Applications that need to read in
application-specific attributes should create an UnknownAttributeReader implementation and attach it via
Attribute.addAttributeReader(String, UnknownAttributeReader).- See Also:

Constructor Details
-
Unknown
Constructs a new instance for a non-standard attribute.- Parameters:
nameIndex- Index in constant poollength- Content length in bytesbytes- Attribute contentsconstantPool- Array of constants
-
Unknown
Constructs a new instance from another instance. Note that both objects use the same references (shallow copy). Use clone() for a physical copy.- Parameters:
unknown- Source.
