is2WordType

public boolean is2WordType()

Specified by:

is2WordType in class TypeData

isNullType

public boolean isNullType()

Description copied from class: TypeData

Returns false if getName() returns a valid type name.

Overrides:

isNullType in class TypeData

isUninit

public boolean isUninit()

Overrides:

isUninit in class TypeData

merge

public void merge(TypeData t)

Specified by:

merge in class TypeData.AbsTypeVar

toTypeVar

protected TypeData.TypeVar toTypeVar(int dim)

Description copied from class: TypeData

Returns this if it is a TypeVar or a TypeVar that this type depends on. Otherwise, this method returns null. It is used by dfs().
