Method Summary

Modifier and Type	Method and Description
Value.Tuple	bOp(int op, Value rgt) Apply binary operator, 'op', element-wise to Tuples 'this' and 'rgt'.
int	compareTo(Value rgt) Is 'this' Tuple < (-1), > (+1), or equal (0) to 'rgt'? Note, 'this' and rgt must have the same shape.
abstract Value	elt(int i) Returns the i-th elt (forced).
Value.Tuple	elts(int[] ps) Return a sub-Tuple of 'this', made of just the elements at the selected positions, 'ps'.
int	n() For a Tuple consisting entirely of bounded Discrete Values, return the obvious integer encoding, hoping it doesn't overflow.
abstract int	nElts() The number of elements (components, fields) in 'this' Structured Value.
abstract Type.Tuple	type() Return the Type of 'this' Value.
Value.Tuple	uOp(int op) Apply unary operator, 'op', element-wise to 'this' Tuple.
Vector	zip() From 'this' Tuple of Vectors (which is checked), return a zipped Vector of Tuples.

Method Detail

type

public abstract Type.Tuple type()

Description copied from class: Value

Return the Type of 'this' Value.

Specified by:

type in class Value

n

public int n()

For a Tuple consisting entirely of bounded Discrete Values, return the obvious integer encoding, hoping it doesn't overflow.

Overrides:

n in class Value

nElts

public abstract int nElts()

Description copied from class: Value.Structured

The number of elements (components, fields) in 'this' Structured Value.

Specified by:

nElts in class Value.Structured

elts

public Value.Tuple elts(int[] ps)

Return a sub-Tuple of 'this', made of just the elements at the selected positions, 'ps'.

elt

public abstract Value elt(int i)

Returns the i-th elt (forced).

Specified by:

elt in class Value.Structured

uOp

public Value.Tuple uOp(int op)

Apply unary operator, 'op', element-wise to 'this' Tuple. Also see Lexical for op codes.

Overrides:

uOp in class Value

bOp

public Value.Tuple bOp(int op,
                       Value rgt)

Apply binary operator, 'op', element-wise to Tuples 'this' and 'rgt'. Also see Lexical for op codes.

Overrides:

bOp in class Value

compareTo

public int compareTo(Value rgt)

Is 'this' Tuple < (-1), > (+1), or equal (0) to 'rgt'? Note, 'this' and rgt must have the same shape.

Specified by:

compareTo in interface java.lang.Comparable<Value>

Overrides:

compareTo in class Value
