BooleanConstant

(class from pyomo.core.expr.boolean_value)

class pyomo.core.expr.boolean_value.BooleanConstant(value, name=None)

Bases: BooleanValue

An object that contains a constant Logical value.

Constructor Arguments:

value The initial value.

__init__(value, name=None)

Methods

__init__(value[, name])
equivalent_to(other)	Construct an EquivalenceExpression between this BooleanValue and its operand.
getname([fully_qualified, name_buffer])	If this is a component, return the component's name on the owning block; otherwise return the value converted to a string
implies(other)	Construct an ImplicationExpression using method "implies"
is_component_type()	Return True if this class is a Pyomo component
is_constant()	Return True if this Logical value is a constant value
is_expression_type([expression_system])	Return True if this numeric value is an expression
is_fixed()	Return True if this is a non-constant value that has been fixed
is_indexed()	Return True if this Logical value is an indexed object
is_logical_type()	Return True if this class is a Pyomo Boolean object.
is_named_expression_type()	Return True if this numeric value is a named expression
is_numeric_type()	Boolean values are not numeric.
is_parameter_type()	Return False unless this class is a parameter object
is_potentially_variable()
is_reference()	Return True if this object is a reference.
is_relational()	DEPRECATED.
is_variable_type()	Return False unless this class is a variable object
land(other)	Construct an AndExpression (Logical And) between this BooleanValue and other.
lor(other)	Construct an OrExpression (Logical OR) between this BooleanValue and other.
pprint([ostream, verbose])
to_string([verbose, labeler, smap, ...])	Return a string representation of the expression tree.
xor(other)	Construct an XorExpression using method "xor"

Member Documentation

equivalent_to(other)

Construct an EquivalenceExpression between this BooleanValue and its operand.

getname(fully_qualified=False, name_buffer=None)

If this is a component, return the component’s name on the owning block; otherwise return the value converted to a string

implies(other)

Construct an ImplicationExpression using method “implies”

is_component_type()

Return True if this class is a Pyomo component

is_constant()

Return True if this Logical value is a constant value

is_expression_type(expression_system=None)

Return True if this numeric value is an expression

is_fixed()

Return True if this is a non-constant value that has been fixed

is_indexed()

Return True if this Logical value is an indexed object

is_logical_type()

Return True if this class is a Pyomo Boolean object.

Boolean objects include constants, variables, or logical expressions.

is_named_expression_type()

Return True if this numeric value is a named expression

is_numeric_type()

Boolean values are not numeric.

is_parameter_type()

Return False unless this class is a parameter object

is_reference()

Return True if this object is a reference.

is_relational()

DEPRECATED.

Return True if this Logical value represents a relational expression.

Deprecated since version 6.4.3: is_relational() is deprecated in favor of is_expression_type(ExpressionType.RELATIONAL)

is_variable_type()

Return False unless this class is a variable object

land(other)

Construct an AndExpression (Logical And) between this BooleanValue and other.

lor(other)

Construct an OrExpression (Logical OR) between this BooleanValue and other.

to_string(verbose=None, labeler=None, smap=None, compute_values=False)

Return a string representation of the expression tree.

Parameters:

• verbose (bool) – If True, then the the string representation consists of nested functions. Otherwise, the string representation is an algebraic equation. Defaults to False.

• labeler – An object that generates string labels for variables in the expression tree. Defaults to None.

Returns:

A string representation for the expression tree.

xor(other)

Construct an XorExpression using method “xor”
