Method Detail

getBytes

public byte[] getBytes()

Description copied from interface: WrappedBytes

The backing array if there is one otherwise null is returned. Callers should use WrappedBytes.backArrayOffset() to know where to read the bytes from. This byte[] should never be modified by the caller

Specified by:

getBytes in interface WrappedBytes

Returns:

the backing byte[] if there is one.

backArrayOffset

public int backArrayOffset()

Description copied from interface: WrappedBytes

The offset of where data starts in the backed array.

Specified by:

backArrayOffset in interface WrappedBytes

Returns:

-1 if there is no backed array otherwise ≥ 0 if there is backing array

getLength

public int getLength()

Description copied from interface: WrappedBytes

The length of the underlying wrapped bytes. This will always be ≥ 0.

Specified by:

getLength in interface WrappedBytes

Returns:

how many bytes are available from the underlying wrapped implementation

getByte

public byte getByte(int offset)

Description copied from interface: WrappedBytes

Retrieves the byte given an offset. This offset should always be less than WrappedBytes.getLength().

Specified by:

getByte in interface WrappedBytes

Parameters:

offset - the offset of where to find the byte

Returns:

the byte at this position

equals

public boolean equals(Object o)

Overrides:

equals in class Object

equalsWrappedBytes

public boolean equalsWrappedBytes(WrappedBytes other)

Specified by:

equalsWrappedBytes in interface WrappedBytes

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
