Method Detail

getObject

Object getObject(int index)

Get the Java Object representation of the element at the specified position. Useful for testing.

Parameters:

index - Index of the value to get

Returns:

the friendly java type

getValueCount

int getValueCount()

Returns:

the number of values that is stored in this vector.

isNull

boolean isNull(int index)

Parameters:

index - the index to check for nullity

Returns:

true if the value at the given index is null, false otherwise.

getNullCount

int getNullCount()

Returns:

the number of null values
