public void setCompProperty(int idx,
                            Property prop)

Sets a property indexed by component.

getNumComponents

protected int getNumComponents()

Gets the number of components.

setCODProperty

public void setCODProperty(Property prop)

Sets the coding style default property.

setQCDProperty

public void setQCDProperty(Property prop)

Sets the quantization default property.

setPOCProperty

public void setPOCProperty(Property prop)

Sets the progression order change property.
