Overrides the writing code method

Specified by:

writeCode in interface ParseTree

Overrides:

writeCode in class NonLeaf

setPackage

public void setPackage(String qn)

Sets the package of this compilation unit

Parameters:

qn - the qualified name indicating this package

getPackage

public String getPackage()

Obtains the package of this compilation unit

Returns:

the qualified name indicating this package
