Direct Known Subclasses:

BinaryOperator

public abstract class BinaryPredicate<T,U,R,F extends PredicateBiFunction<T,U,R>>
extends BinaryScalarFunction

Binary operator. Operators act as _special_ functions in that they have a symbol instead of a name and do not use parentheses. Further more they are not registered as the rest of the functions as are implicit to the language.

Method Details

fold

public R fold(FoldContext ctx)

Description copied from class: Expression

Evaluate this expression statically to a constant. It is an error to call this if Expression.foldable() returns false.

Overrides:

fold in class Expression

hashCode

public int hashCode()

Overrides:

hashCode in class Function

equals

public boolean equals(Object obj)

Overrides:

equals in class Function

symbol

public String symbol()

function

public F function()

nodeString

public void nodeString(StringBuilder sb,
 Node.NodeStringFormat format)

Description copied from class: Node

Append this Node's string representation to sb. This does not include this node's Node.children().

Overrides:

nodeString in class Function

Parameters:

sb - target for the string

format - configuration for rendering the string representation
