java.lang.Objectjavolution.io.Struct.Member
protected class Struct.Member
This inner class represents the base class for all Struct
members. It allows applications to define additional member types.
For example:
public class MyStruct extends Struct {
BitSet bits = new BitSet(256);
...
public BitSet extends Member {
public BitSet(int nbrBits) {
super(nbrBits, 0); // Direct bit access.
}
public boolean get(int i) { ... }
public void set(int i, boolean value) { ...}
}
}

protected Struct.Member(int bitLength, int wordSize)
offset()
of the member does not change, only bitIndex()
is
incremented.
bitLength
- the number of bits or 0
to force next member on next word boundary.wordSize
- the word size in bytes used when accessing
this member data or 0
if the data is accessed
at the bit level.Method Detail |
