Interface PredicateDefinition

All Superinterfaces:

NodeType

All Known Implementing Classes:

PredicateDefinitionVo

public interface PredicateDefinition
extends NodeType

Definition of operator. This is a predicate constant. For example the predicate "x is a set" could be defined in MK with the formula "\exists y: x \in y".

There must also be the possibility to define basic predicate constants like "x is element of y".

Method Detail

getArgumentNumber

java.lang.String getArgumentNumber()

Get number of arguments for the defined object. Carries information about the argument number the defined object needs.

Returns:

Argument number.

getName

java.lang.String getName()

This name together with getArgumentNumber() identifies a predicate.

Returns:

Name of defined predicate.

getLatexPattern

java.lang.String getLatexPattern()

Get LaTeX output for definition. The replaceable arguments must are marked as "#1", "#2" and so on. For example "\mathfrak{M}(#1)"

Returns:

LaTeX pattern for definition type setting.

getFormula

Formula getFormula()

Get complete formula. That is an equivalence between the new predicate and the defining formula.

Returns:

Complete formula.

getDescription

LatexList getDescription()

Get description. Only necessary if formula is not self-explanatory.

Returns:

Description.
