Method Detail

type

public Class type()

Returns the type of this composite value.

Specified by:

type in interface Denotable

isNull

public boolean isNull()

Returns true if this value represents null. This method always returns false.

Specified by:

isNull in interface Denotable

isEquivalentTo

public boolean isEquivalentTo(Denotable other)

Returns true if the represented value is equivalent to the argument's represented value.

Specified by:

isEquivalentTo in interface Denotable

hasEquals

protected boolean hasEquals()

Returns true if the type of the represented value has its own equals method defined.

elems

protected Denotable[] elems()

Returns the component values.

getTypeName

static String getTypeName(Class clazz)

Returns the printable name of the given class. For example, given the int array type, this method returns int[].

code
