Method Detail

begin

public void begin()

Specified by:

begin in interface DXFGroupActor

end

public void end()

Specified by:

end in interface DXFGroupActor

resetToDefaults

public void resetToDefaults()

Resets all values to defaults; useful when reusing objects. Subclasses overriding this should prefix their own method bodies with:

 super.resetToDefaults();
 

processGroup

public void processGroup(int code,
                         DXFProtoValue value)

Acts on groups; interprets them and populates properties. Subclasses will generally override this; they should prefix their own methods however with:

        // let superclass do its thing, skip any codes inside app-specific
        // bracketed section
        super.processGroup(code, value);
        if (insideAppGroup)
                return;
 

Specified by:

processGroup in interface DXFGroupActor

copyStateFrom

public void copyStateFrom(DXFEntity nother)

Copies the attributes from the given DXFEntity. Subclasses should implement this, but call it as well:

 public void copyState(DXFEntity nother) {
    super.copyStateFrom(nother);
    someState = nother.someState;
    ....
 

clone

public java.lang.Object clone()

The default reader reuses objects heavily; clone them if you need your own version. Utilizes copyState() so subclasses do not need to override this.

Overrides:

clone in class java.lang.Object
