Method Details

byteAt

public abstract byte byteAt(long i)

Gets the byte at the specified position. Result is undefined if out of range.

Parameters:

i - Index of the byte to get

Returns:

The byte at the specified position

empty

public abstract ABlobLike<T> empty()

Description copied from class: ACountable

Returns a canonical, singleton empty instance of the same type as this Countable value.

Specified by:

empty in class ACountable<T extends ACell>

Returns:

An empty Countable value

getBytes

public byte[] getBytes()

Gets a byte array containing a copy of this Blob.

Returns:

A new byte array containing the contents of this blob.

getBytes

public abstract int getBytes(byte[] dest,
 int destOffset)

Copies the bytes from this instance to a given destination

Parameters:

dest - Destination array

destOffset - Offset into destination array

Returns:

End position in destination array after writing
