Class calypso.util.SignedInteger
java.lang.Object | +----calypso.util.SignedInteger
Utility class that represents the parse state from parsing a signed integer. The sign of the integer is maintained so that "10" can be distinguished from "+10". In addition, we can optionally handle numbers expressed as percentages.

Fields
• PLUS
public static final int PLUS
• MINUS
public static final int MINUS
• NONE
public static final int NONE
• fValue
protected int fValue
• fSign
protected int fSign
• fPct
protected boolean fPct
Constructors
• SignedInteger
public SignedInteger(String aString, boolean aAllowPct) throws NumberFormatException
The integer part works (almost) the same as atoi():
- Skip leading white spaces.
- Non-digit char terminates convertion.
- If got a valid integer, don't throw NumberFormatException.
- Throw exception if first nonspace char is not digit(atoi returns 0). Example: " +4z" works as 4.
• SignedInteger
public SignedInteger(int aValue,
int aSign)
Methods
• intValue
public int intValue()
• isPct
public boolean isPct()
• computeValue
public int computeValue(int aBaseValue)
Compute a value based on "aBaseValue". Apply the sign of this SignedInteger to determine the value to return.
• getSign
public int getSign()
Return the sign of the value.
• toString
public String toString()
