Methods
equals(other)
Compares this ring and the input ring.
Parameters:
| Name | Type | Description |
|---|---|---|
other |
Other instance of subclass of this class. |
- Overrides:
- Source:
Returns:
true or false depending on if this ring equals the
other. This is based on deep comparison of content.
getByteLength()
Fixed number of bytes needed to represent a ring
element.
- Overrides:
- Source:
Returns:
Fixed number of bytes used to represent ring elements.
getEncodeLength()
Fixed number of bytes that can be encoded into a ring
element.
- Overrides:
- Source:
Returns:
Fixed number of bytes that can be encoded into a ring
element.
getONE()
Unit element of this ring.
- Overrides:
- Source:
Returns:
Unit element of this ring.
getPField()
Returns the underlying prime order field.
- Overrides:
- Source:
Returns:
Underlying prime order field.
getWidth()
Product width of this ring.
- Source:
Returns:
Product width of this ring.
getZERO()
Zero of the this ring.
- Overrides:
- Source:
Returns:
Zero of this ring.
prod()
Forms a product element formed from the given list of
elements which are required to belong to the corresponding
components of this ring, or from a single element from the
underlying ring (in which case it is simply repeated). The latter
case requires that the product ring is formed from identical
components.
- Source:
Returns:
Product element formed from the inputs.
project()
ith component of this product ring.
- Source:
Returns:
ith component of this product ring.
randomElement(randomSource, statDist)
Generates a random element in the ring.
Parameters:
| Name | Type | Description |
|---|---|---|
randomSource |
Source of randomness. | |
statDist |
Statistical distance from the uniform distribution assuming a perfect random source. |
- Overrides:
- Source:
Returns:
Randomly chosen element from the ring.
randomElementByteLength(statDist)
Number of random bytes needed to derive a random
element with the given statistical distance to uniform.
Parameters:
| Name | Type | Description |
|---|---|---|
statDist |
Statistical distance from the uniform distribution assuming a perfect random source. |
- Overrides:
- Source:
Returns:
Number of random bytes needed to derive a random element.
toElement(byteTree)
Recovers an element from the input byte tree.
Parameters:
| Name | Type | Description |
|---|---|---|
byteTree |
Byte tree representation of an element. |
- Overrides:
- Source:
Returns:
Element represented by the byte tree.
toString()
Compiles a human readable representation of this field.
- Overrides:
- Source:
Returns:
Human readable representation of this field.
