Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`Value`	`add(Value value)`
`Value`	`and(Value value)`
`boolean`	`asBoolean()`	Returns this value as a boolean.
`double`	`asDouble()`	Returns the hashcode of this, to enable strings to be encoded (with reasonable safely) as doubles for optimization
`Value`	`asMutable()`	Returns this is mutable, or a mutable copy otherwise
`String`	`asString()`	Returns the value of this as a string
`com.yahoo.tensor.Tensor`	`asTensor()`	Returns this as a tensor value
`Value`	`compare(TruthOperator operator, Value value)`	Perform the comparison specified by the operator between this value and the given value
`Value`	`divide(Value value)`
`boolean`	`equals(Object other)`
`static StringValue`	`frozen(String value)`	Create a string value which is frozen at the outset.
`Value`	`function(Function function, Value value)`	Perform the given binary function on this value and the given value
`boolean`	`hasDouble()`	Returns true if this value can return itself as a double, i.e asDoubleValue will return a value and not throw
`int`	`hashCode()`
`Value`	`modulo(Value value)`
`Value`	`multiply(Value value)`
`Value`	`negate()`
`Value`	`not()`
`Value`	`or(Value value)`
