Constructor Detail

NullType

public NullType()

Constructs a NullType.

Throws:

IllegalArgumentException - If any parameter to the constructor is null.

Method Detail

apply

public <RetType> RetType apply(TypeVisitor<RetType> visitor)

Specified by:

apply in class Type

apply

public void apply(TypeVisitor_void visitor)

Specified by:

apply in class Type

toString

public String toString()

Implementation of toString that uses output(java.io.Writer) to generate a nicely tabbed tree.

Overrides:

toString in class Object

output

public void output(Writer writer)

Prints this object out as a nicely tabbed tree.

Specified by:

output in class Type

equals

public boolean equals(Object obj)

Implementation of equals that is based on the values of the fields of the object. Thus, two objects created with identical parameters will be equal.

Overrides:

equals in class Object

generateHashCode

public int generateHashCode()

Implementation of hashCode that is consistent with equals. The value of the hashCode is formed by XORing the hashcode of the class object with the hashcodes of all the fields of the object.

Specified by:

generateHashCode in class ReferenceType

walk

public void walk(TreeWalker w)

Specified by:

walk in class Type
