signature_index
private int signature_index
Signature
public Signature(Signature c)
- Initialize from another object. Note that both objects use the same
references (shallow copy). Use clone() for a physical copy.
Signature
Signature(int name_index,
int length,
java.io.DataInputStream file,
ConstantPool constant_pool)
throws java.io.IOException
- Construct object from file stream.
- Parameters:
name_index
- Index in constant pool to CONSTANT_Utf8length
- Content length in bytesfile
- Input streamconstant_pool
- Array of constants
- Throws:
