Class BytesTransformer.ResizeTransformer

java.lang.Object

at.favre.lib.bytes.BytesTransformer.ResizeTransformer

All Implemented Interfaces:

BytesTransformer

Enclosing interface:

BytesTransformer

public static final class BytesTransformer.ResizeTransformer
extends Object
implements BytesTransformer

Copies the specified array, truncating or padding with zeros (if necessary) so the copy has the specified length. For all indices that are valid in both the original array and the copy, the two arrays will contain identical values. For any indices that are valid in the copy but not the original, the copy will contain (byte)0.

If if the internal array will be grown, zero bytes will be added on the left, keeping the value the same.

Method Detail

transform

public byte[] transform(byte[] currentArray,
                        boolean inPlace)

Description copied from interface: BytesTransformer

Transform given victim in place, overwriting its internal byte array

Specified by:

transform in interface BytesTransformer

Parameters:

currentArray - to preform the transformation on

inPlace - perform the operations directly on the victim's byte array to omit copying of the internal array

Returns:

resulting bytes (either the overwritten instance or a new one)

supportInPlaceTransformation

public boolean supportInPlaceTransformation()

Description copied from interface: BytesTransformer

If this transformer supports transformation without creation a new array

Specified by:

supportInPlaceTransformation in interface BytesTransformer

Returns:

true if supported
