public interface Type

extends Nameable

A NODAL data type.

A data type in NODAL is represented by an instance of Type, and each such instance represents an ability to check for the type validity of various potential inputs (via the accepts methods), and an ability to convert to an acceptable type (via the as methods).

Method Detail

type

public Type type()

The base Type associated with this interface.

Interfaces that extend the Type interface should override this method to refer back to the Type from which they are derived.

accepts

public boolean accepts(boolean b)

Check that this type accepts the boolean value.

accepts

public boolean accepts(char c)

Check that this type accepts the char value.

accepts

public boolean accepts(byte b)

Check that this type accepts the byte value.

accepts

public boolean accepts(short s)

Check that this type accepts the short value.

accepts

public boolean accepts(int i)

Check that this type accepts the int value.

accepts

public boolean accepts(long l)

Check that this type accepts the long value.

public boolean accepts(float s)

Check that this type accepts the float value.

accepts

public boolean accepts(double d)

Check that this type accepts the double value.

acceptsString

public boolean acceptsString(java.lang.String s)

Check that this type accepts the String.

acceptsNode

public boolean acceptsNode(Node n)

accepts

public boolean accepts(java.lang.Object v)

Check that this type accepts the Object.

acceptsType

public boolean acceptsType(Type t)

Check that this type accepts a value with the given Type.

This is a much more specific test than the value-based accepts tests, since it returns true only if all values of the parameter type are accepted by this Type. As such, this function tests a strict sub-type relationship.
