Class AWUtil

java.lang.Object

net.automatalib.common.smartcollection.AWUtil

public final class AWUtil
extends Object

Utility class for writing containers to arrays.

It is generally preferable to use the static methods this class offers than using ArrayWritable.writeToArray(int, Object[], int, int) directly.

Method Summary

Modifier and Type	Method	Description
static <T,U extends T> int	safeWrite(int num, ArrayWritable<U> aw, int ofs, T[] array, int tgtOfs)

Method Detail

safeWrite

public static <T,U extends T> int safeWrite(ArrayWritable<U> aw,
                                                  T[] array)

Writes the complete container data to an array. This method ensures that the array's capacity is not exceeded.

Type Parameters:

T - the array type

U - the container type

Parameters:

aw - the container.

array - the array

Returns:

the number of elements copied

safeWrite

public static <T,U extends T> int safeWrite(int num,
                                                  ArrayWritable<U> aw,
                                                  T[] array)

Writes a given maximum amount of data items from a container to an array. This method ensures that the array's capacity is not exceeded.

Type Parameters:

T - the array type

U - the container type

Parameters:

num - the number of elements to copy

aw - the container.

array - the array

Returns:

the number of elements copied
