Detailed Description

The class IntExpr is the base of all integer expressions in
constraint programming.
It contains the basic protocol for an expression:

  • setting and modifying its bound
  • querying if it is bound
  • listening to events modifying its bounds
  • casting it into a variable (instance of IntVar)

Constructor & Destructor Documentation

◆ IntExpr()

com.google.ortools.constraintsolver.IntExpr.IntExpr ( long cPtr,
boolean cMemoryOwn )
protected

Definition at line 23 of file IntExpr.java.

Member Function Documentation

◆ accept()

void com.google.ortools.constraintsolver.IntExpr.accept ( ModelVisitor visitor)

Accepts the given visitor.

Reimplemented in com.google.ortools.constraintsolver.IntVar.

Definition at line 148 of file IntExpr.java.

◆ bound()

boolean com.google.ortools.constraintsolver.IntExpr.bound ( )

Returns true if the min and the max of the expression are equal.

Reimplemented in com.google.ortools.constraintsolver.BooleanVar.

Definition at line 101 of file IntExpr.java.

◆ delete()

synchronized void com.google.ortools.constraintsolver.IntExpr.delete ( )

Reimplemented from com.google.ortools.constraintsolver.PropagationBaseObject.

Reimplemented in com.google.ortools.constraintsolver.BaseIntExpr, com.google.ortools.constraintsolver.BooleanVar, and com.google.ortools.constraintsolver.IntVar.

Definition at line 49 of file IntExpr.java.

◆ finalize()

void com.google.ortools.constraintsolver.IntExpr.finalize ( )
protected

Reimplemented from com.google.ortools.constraintsolver.PropagationBaseObject.

Reimplemented in com.google.ortools.constraintsolver.BaseIntExpr, com.google.ortools.constraintsolver.BooleanVar, and com.google.ortools.constraintsolver.IntVar.

Definition at line 45 of file IntExpr.java.

◆ getCPtr()

static long com.google.ortools.constraintsolver.IntExpr.getCPtr ( IntExpr obj)
staticprotected

Definition at line 28 of file IntExpr.java.

◆ isVar()

boolean com.google.ortools.constraintsolver.IntExpr.isVar ( )

Returns true if the expression is indeed a variable.

Reimplemented in com.google.ortools.constraintsolver.IntVar.

Definition at line 108 of file IntExpr.java.

◆ max()

long com.google.ortools.constraintsolver.IntExpr.max ( )

Reimplemented in com.google.ortools.constraintsolver.BooleanVar.

Definition at line 68 of file IntExpr.java.

◆ min()

long com.google.ortools.constraintsolver.IntExpr.min ( )

Reimplemented in com.google.ortools.constraintsolver.BooleanVar.

Definition at line 60 of file IntExpr.java.

◆ range()

void com.google.ortools.constraintsolver.IntExpr.range ( long[] l,
long[] u )

By default calls Min() and Max(), but can be redefined when Min and Max
code can be factorized.

Definition at line 80 of file IntExpr.java.

◆ setMax()

void com.google.ortools.constraintsolver.IntExpr.setMax ( long m)

Reimplemented in com.google.ortools.constraintsolver.BooleanVar.

Definition at line 72 of file IntExpr.java.

◆ setMin()

void com.google.ortools.constraintsolver.IntExpr.setMin ( long m)

Reimplemented in com.google.ortools.constraintsolver.BooleanVar.

Definition at line 64 of file IntExpr.java.

◆ setRange()

void com.google.ortools.constraintsolver.IntExpr.setRange ( long l,
long u )

This method sets both the min and the max of the expression.

Reimplemented in com.google.ortools.constraintsolver.BooleanVar.

Definition at line 87 of file IntExpr.java.

◆ setValue()

void com.google.ortools.constraintsolver.IntExpr.setValue ( long v)

This method sets the value of the expression.

Definition at line 94 of file IntExpr.java.

◆ swigRelease()

static long com.google.ortools.constraintsolver.IntExpr.swigRelease ( IntExpr obj)
staticprotected

Definition at line 32 of file IntExpr.java.

◆ var()

IntVar com.google.ortools.constraintsolver.IntExpr.var ( )

Creates a variable from the expression.

Reimplemented in com.google.ortools.constraintsolver.BaseIntExpr, and com.google.ortools.constraintsolver.IntVar.

Definition at line 115 of file IntExpr.java.

◆ varWithName()

IntVar com.google.ortools.constraintsolver.IntExpr.varWithName ( String name)

Creates a variable from the expression and set the name of the
resulting var. If the expression is already a variable, then it
will set the name of the expression, possibly overwriting it.
This is just a shortcut to Var() followed by set_name().

Definition at line 126 of file IntExpr.java.

◆ whenRange() [1/2]

void com.google.ortools.constraintsolver.IntExpr.whenRange ( Demon d)

Attach a demon that will watch the min or the max of the expression.

Reimplemented in com.google.ortools.constraintsolver.BooleanVar.

Definition at line 134 of file IntExpr.java.

◆ whenRange() [2/2]

void com.google.ortools.constraintsolver.IntExpr.whenRange ( Runnable closure)

Attach a demon that will watch the min or the max of the expression.
