EMPTY

public static final byte[] EMPTY

Method Detail

allocate

public static HeapBytes allocate(int size)

Allocates a new heap byte array.

Parameters:

size - The count of the buffer to allocate (in bytes).

Returns:

The heap buffer.

Throws:

IllegalArgumentException - If count is greater than the maximum allowed count for an array on the Java heap - Integer.MAX_VALUE - 5

wrap

public static HeapBytes wrap(byte[] bytes)

Wraps the given bytes in a UnsafeHeapBytes object.

The returned Bytes object will be backed by a HeapMemory instance that wraps the given byte array. The Bytes.size() will be equivalent to the provided by array length.

Parameters:

bytes - The bytes to wrap.

hasArray

public boolean hasArray()

Description copied from interface: Bytes

Returns whether the bytes has an array.

Returns:

Whether the bytes has an underlying array.
