8.7.11. GenConstr¶

class GenConstr¶

Represent a general constraint.

Properties

index

The index position of the general constraint

index¶: The index position of the general constraint.

Methods

`getAttr()`	Obtain the attribute value of a general constraint
`sameAs()`	Test whether the general constraint is the same as another general constraint
`setAttr()`	Set the attribute value of general constraint

getAttr(attrname)¶

Obtain the attribute value of a general constraint.

Parameters: attrname – Attribute name

Note

Attributes can also be read and written directly through object attributes, in this case, the attribute name is case-insensitive

sameAs(genconstr)¶

Test whether the general constraint is the same as another general constraint.

Parameters: genconstr – Another general constraint to be tested.
Returns: A boolean result indicating whether the two general constraints are the same.

example:

m = Model()
b = m.addVar(vtype='B')
x = m.addVar()
y = m.addVar()
gc = m.addGenConstrIndicator(b, True, x + y <= 3)
print(gc.sameAs(m.getGenConstrs()[0]))

setAttr(attrname, attrvalue)¶

Set the attribute value of general constraint.

Parameters

attrname – The name of the attribute.
attrvalue – The value of the attribute to be set.

Note

Attribute can also be read and written directly through object attributes; in this case, the attribute name is case-insensitive.
