Constructor Detail


public PofSparseArray(PofValue valueParent,
                      ReadBuffer bufValue,
                      PofContext ctx,
                      int of,
                      int nType,
                      int ofChildren)
Construct a PofSparseArray instance wrapping the supplied buffer.
valueParent - parent value within the POF stream
bufValue - buffer containing POF representation of this value
ctx - POF context to use when reading or writing properties
of - offset of this value from the beginning of POF stream
nType - POF type identifier for this value
ofChildren - offset of the first child element within this value

Method Detail


protected PofValue findChildInternal(int nIndex,
                                     int ofStart,
                                     int iStart)
Find the child value with the specified index.
Specified by:
findChildInternal in class ComplexPofValue
nIndex - index of the child value to find
ofStart - offset within the parent buffer to start search from
iStart - index of the child value to start search from
the child value


protected PofSparseArray.NilPofValue instantiateNilValue(int of,
                                                         int nIndex)
Instantiate a PofSparseArray.NilPofValue (factory method).
of - offset this value would be at if it existed
nIndex - index of this value within the parent sparse array
a NilPofValue instance
