get. This me thod returns the element at the specified one-based offset in

this array. The returned element is converted to a Java array using default

method i s equivalent to calling

getField(index).toArray().

public Object get(int index)

public Object get(int[] index)

To get the element at a specific index and structure field, use one of the

following. Calling this method is equivalent to calling

getField(fieldname,

index).toArray()

public Object get(String fieldname, int index)

public Object get(String fieldname, int[] index)

Use the first syntax (int index) to return the ele ment at the specified

one-based offset in the a rray, accessing elements in column-wise order. Us e the

second syntax (

int[] index) to return the element at the specified array of

one-based indices. The first syntax offers better performance than the second.
