public class WrapperObjectInputStream
This is an imitation ObjectInputStream class that provides the ObjectInput interface by delegating to an object that implements the ObjectInput interface. Primarily, this is intended as a base class for building specific-purpose ObjectInput wrappers.
Constructor Summary | |
---|---|
WrapperObjectInputStream(ObjectInput in)
Construct a WrapperObjectInputStream that will read from the specified object implementing the ObjectInput interface. |
Method Summary | |
---|---|
int |
available()
Returns the number of bytes that can be read (or skipped over) from this input stream without causing a blocking I/O condition to occur. |
void |
close()
Close the InputStream and release any system resources associated with it. |
ObjectInput |
getObjectInput()
Obtain the underlying object providing the ObjectInput interface that this object is delegating to. |
int |
read()
Read the next byte of data from the InputStream. |
int |
read(byte[] ab)
Read some number of bytes from the input stream and store them into the passed array ab . |
int |
read(byte[] ab,
int of,
int cb)
Read up to cb bytes from the input stream and store them
into the passed array ab starting at offset
of . |
Object |
readObject()
Read and return an object. |
long |
skip(long cb)
Skips over up to the specified number of bytes of data from this InputStream. |
