Constructor Detail

Unknown

public Unknown(Unknown c)
Initialize from another object. Note that both objects use the same references (shallow copy). Use clone() for a physical copy.

Unknown

public Unknown(int name_index,
               int length,
               byte[] bytes,
               ConstantPool constant_pool)
Create a non-standard attribute.
Parameters:
name_index - Index in constant pool
length - Content length in bytes
bytes - Attribute contents
constant_pool - Array of constants
Method Detail

accept

public void accept(Visitor v)
Called by objects that are traversing the nodes of the tree implicitely defined by the contents of a Java class. I.e., the hierarchy of methods, fields, attributes, etc. spawns a tree of objects.
Parameters:
v - Visitor object
Overrides:
accept in class Attribute

dump

public final void dump(java.io.DataOutputStream file)
               throws java.io.IOException
Dump unknown bytes to file stream.
Parameters:
file - Output file stream
Overrides:
dump in class Attribute

getBytes

public final byte[] getBytes()
Returns:
data bytes.

getName

public final java.lang.String getName()
Returns:
name of attribute.

setBytes

public final void setBytes(byte[] bytes)
Parameters:
bytes. -  

toString

public final java.lang.String toString()
Returns:
String representation.
Overrides:
toString in class Attribute

copy

public Attribute copy(ConstantPool constant_pool)
Returns:
deep copy of this attribute
