Constructor Detail

StepData

public StepData(byte[] data)

Create a new data object from an array of bytes.

Method Detail

getData

public byte[] getData()

Get the underlying byte data for this object.

equals

public boolean equals(Object o)

Compare two data objects for equality.

The objects are equivalent if their data are the same size and contain the same values.

The algorithm is fail-fast.

Specified by:

equals in interface StepObject

Overrides:

equals in class Object

hashCode

public int hashCode()

Get the hash-code for this object.

Algorithm:

 for (i=0; i<value.length; i++)
   code = (code << 1) ^ (hashCode[i]);
 

Specified by:

hashCode in interface StepObject

Overrides:

hashCode in class Object

equals(Object)

toString

public String toString()

Get a text version of this data object.

The output is a list of byte values in hexadecimal.

Overrides:

toString in class Object
