                 String val,
                 LevelFactory lf)

Method Detail

hashCode

public int hashCode()

It retrieves the integer value of the level.

Overrides:

hashCode in class Object

getStringValue

public String getStringValue()

It retrieves the string expression of the level. ex: 'DEBUG + 1'

evaluate

public static int evaluate(String expr,
                           LevelFactory lf)

It analyzes a string expression to obtain its integer value. The allowed expression type are the following:

• an integer value
• another level name
• levelName + integerValue
• levelName - integerValue

Parameters:

expr - is the string expression which must be evaluated.

lf - is the LevelFactory which permits to obtain the referenced level.

Returns:

an integer value or 0 if it is impossible to evaluate the expression.
