type

public BtrpOperand.Type type()

Description copied from interface: BtrpOperand

Get the type of the operand.

Returns:

a type

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

Overrides:

toString in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

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

plus

public BtrpString plus(BtrpOperand o)

Description copied from interface: BtrpOperand

Computes the addition of this operand with another one.

Specified by:

plus in interface BtrpOperand

Overrides:

plus in class DefaultBtrpOperand

Parameters:

o - the other operand

Returns:

the result of the addition
