示例1: read_blockdata
public BlockData read_blockdata( byte tc, DataInputStream dis ) throws IOException
{
int size;
if ( tc == ObjectStreamConstants.TC_BLOCKDATA ) {
size = dis.readUnsignedByte();
}
else if ( tc == ObjectStreamConstants.TC_BLOCKDATALONG ) {
size = dis.readInt();
}
else {
throw new IOException( "invalid tc value for blockdata: " + hex( tc ) );
}
if ( size < 0 ) {
throw new IOException( "invalid value for blockdata size: " + size );
}
byte[] b = new byte[size];
dis.readFully( b );
debug( "read blockdata of size " + size );
return new BlockData( b );
}
示例2: read_Content
/**
* <p>
* Read the next object corresponding to the spec grammar rule "content", and return
* an object of type content.
* </p>
*
* <p>
* Usually, there is a 1:1 mapping of content items and returned instances. The
* one case where this isn't true is when an exception is embedded inside another
* object. When this is encountered, only the serialized exception object is
* returned; it's up to the caller to backtrack in order to gather any data from the
* object that was being serialized when the exception was thrown.
* </p>
*
* @param tc
* the last byte read from the stream; it must be one of the TC_* values
* within ObjectStreamConstants.*
* @param dis
* the DataInputStream to read from
* @param blockdata
* whether or not to read TC_BLOCKDATA (this is the difference
* between spec rules "object" and "content").
* @return an object representing the last read item from the stream
* @throws IOException
* when a validity or I/O error occurs while reading
