Constructor Detail

Condition

public Condition(int type,
                 int lower,
                 int upper)

Public constructor that builds a condition from the type, lower bound and upper bound.

Parameters:

type - the type of the condition.

lower - the lower bound; not used if it's a less than

upper - the upper bound of the condition; not used if it's a greater than.

Condition

public Condition()

Public constructor for an unspecified condition.

Method Detail

equals

public boolean equals(java.lang.Object o)

getType

public int getType()

Getter for the type attribute.

Returns:

the type attribute's value.

getUpper

public int getUpper()

Getter for the upper attribute.

Returns:

the upper attribute's value.

getLower

public int getLower()

Getter for the lower attribute.

Returns:

the lower attribute's value.

hashCode

public int hashCode()

The hashCode function is implemented to return the type of the condition. It returns the same value in case of two different conditions that have the same type (e.g. greater than 500 and greater than 200), but the equals method is precise enough so that the matching will be correct.

toReadableString

public java.lang.String toReadableString()
