Method Detail

create

public static FieldInfo create(DataInput in,
                               ClassFile classFile)
                        throws InvalidByteCodeException,
                               IOException
Factory method for creating FieldInfo structures from a DataInput.

Parameters:
in - the DataInput from which to read the FieldInfo structure
classFile - the parent class file of the structure to be created
Returns:
the new FieldInfo structure
Throws:
InvalidByteCodeException - if the byte code is invalid
IOException - if an exception occurs with the DataInput

read

public void read(DataInput in)
          throws InvalidByteCodeException,
                 IOException
Description copied from class: AbstractStructure
Read this structure from the given DataInput.

Excpects DataInput to be in JVM class file format and just before a structure of this kind. No look ahead parsing since the class file format is deterministic.

Overrides:
read in class ClassMember
Throws:
InvalidByteCodeException
IOException

write

public void write(DataOutput out)
           throws InvalidByteCodeException,
                  IOException
Description copied from class: AbstractStructure
Write this structure to the given DataOutput.

The written bytes are in JVM class file format.

Overrides:
write in class ClassMember
Throws:
InvalidByteCodeException
IOException

debug

protected void debug(String message)
Description copied from class: AbstractStructure
Utility method for derived structures. Dump a specific debug message.

Overrides:
debug in class AbstractStructure
Parameters:
message - the debug message
