(package private) | Unknown(int name_index, int length, DataInputStream file, ConstantPool constant_pool) Construct object from file stream. |
Unknown
public Unknown()
- Empty constructor, all attributes have to be defined via `setXXX'
methods. Use at your own risk.
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
Unknown
Unknown(int name_index, int length, DataInputStream file, ConstantPool constant_pool)
throws java.io.IOException
- Construct object from file stream.
- Parameters:
- name_index - Index in constant pool
- length - Content length in bytes
- file - Input stream
- constant_pool - Array of constants
- throw IOException
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
dump
public final void dump(DataOutputStream file)
throws java.io.IOException
- Dump unknown bytes to file stream.
- Parameters:
- file - Output file stream
- throw IOException
getBytes
public final byte[] getBytes()
- Returns: data bytes.
getConstantPool
public final ConstantPool getConstantPool()
- Returns: Constant pool used by this object.
- See Also:
- ConstantPool
getName
public final String getName()
- Returns: name of attribute.
getUnknownAttributes
static Unknown[] getUnknownAttributes()
- Returns: array of unknown attributes, but just one for each kind.
setBytes
public final void setBytes(byte[] bytes)
- Parameters:
- bytes.
setConstantPool
public final void setConstantPool(ConstantPool constant_pool)
- Parameters:
- constant_pool - Constant pool to be used for this object.
- See Also:
- ConstantPool
toString
public final String toString()
- Returns: String representation.
