Description copied from class: Var

Checks whether the type of the given variable is equal or extends this variable's type.
If the result is true, then the given variable can become a link source for this variable

Overrides:

isAssignableFrom in class VarMutable

Returns:

true if the source type is equal or wider than this variable's type, false otherwise (including if source has null type)

getElementAt

public <T> T getElementAt(int index)
               throws java.lang.NullPointerException,
                      java.lang.ClassCastException

Parameters:

index - the index to retrieve

Returns:

the array element at the specified index

Throws:

java.lang.NullPointerException - if the variable value is null

java.lang.ClassCastException - if the inferred type is incompatible with the array element

size

public int size()

Returns:

The size of this array, or -1 if the array is null
