Constructor Details

SymTypeOfNull

@Deprecated
public SymTypeOfNull()

Deprecated.

contains no non-deprecated program logic

This Class represents the type of the value "null". This type doesn't really exist (hence the print method delivers "nullType", i.e. _nullTypeString), but the object is used to attach "null" a proper type, which is then compatible to e.g. to TypeConstant or TypeArray, int[] j = null; ok Integer i2 = null; ok but not e.g. to int int i = null; illegal
