 ValueAccessor<VL> accessorL,
 VR right,
 ValueAccessor<VR> accessorR)

Description copied from class: AbstractType

Implement IFF ComparisonType is CUSTOM Compares the byte representation of two instances of this class, for types where this cannot be done by simple in-order comparison of the unsigned bytes Standard Java compare semantics

Overrides:

compareCustom in class AbstractType<Void>

compose

public <V> Void compose(V value,
 ValueAccessor<V> accessor)

Overrides:

compose in class AbstractType<Void>

decompose

public ByteBuffer decompose(Void value)

Overrides:

decompose in class AbstractType<Void>

getString

public <V> String getString(V value,
 ValueAccessor<V> accessor)

Description copied from class: AbstractType

get a string representation of the bytes used for various identifier (NOT just for log messages)

Overrides:

getString in class AbstractType<Void>

fromString

public ByteBuffer fromString(String str)

Description copied from class: AbstractType

get a byte representation of the given string.

Specified by:

fromString in class AbstractType<Void>

fromJSONObject

public Term fromJSONObject(Object parsed)

Description copied from class: AbstractType

Given a parsed JSON string, return a byte representation of the object.

Specified by:

fromJSONObject in class AbstractType<Void>

Parameters:

parsed - the result of parsing a json string

toJSONString
