BtrpElement

public BtrpElement(BtrpOperand.Type ty, String n, Element el)

Make a new element.

Parameters:

ty - the element type. Either BtrpOperand.Type.VM or BtrpOperand.Type.NODE.

n - the element name

el - the associated BtrPlace element

Method Details

getName

public String getName()

Get the element identifier.

Returns:

a non null String.

getElement

public Element getElement()

Get the element.

Returns:

an element

equals

public boolean equals(Object o)

Check the equality of two elements. Both are equals if they are an instance of a same class and if they contains the same element.

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

degree

public int degree()

Description copied from interface: BtrpOperand

Get the degree of the operand. A degree of 0 indicates a single value. A degree of 1 indicates a set of single value. A degree of 2 indicate a set of set of values. Basically. An operand with a degree n is a set of elements with all having the degree n - 1

Returns:

0

type

public BtrpOperand.Type type()

Description copied from interface: BtrpOperand

Get the type of the operand.

Returns:

a type

eq

public BtrpNumber eq(BtrpOperand other)

Description copied from interface: BtrpOperand

Check if this operand is equals to another one.

Specified by:

eq in interface BtrpOperand

Overrides:

eq in class DefaultBtrpOperand

Parameters:

other - the operand to compare to

Returns:

BtrpNumber.TRUE if both operand are equals, BtrpNumber.FALSE otherwise

copy

public BtrpElement copy()

Description copied from interface: Copyable

Make a deep copy of the object.

Returns:

a deep copy

toString

public String toString()

Overrides:

toString in class Object
