Doc from com.ibm.icu.text.NumberFormat.equals.

Overrides equals. Two NumberFormats are equal they are of the same class and the user-specified values for settings (groupingUsed, parseIntegerOnly, maximumIntegerDigits, etc.) are equal.

Parameters
obj:Object

the object to compare against

Returns:boolean

true if the object is equal to this.

public char[] getDigits()
getMaximumIntegerDigitsback to summary
public int getMaximumIntegerDigits()

Overrides com.ibm.icu.text.NumberFormat.getMaximumIntegerDigits.

Doc from com.ibm.icu.text.NumberFormat.getMaximumIntegerDigits.

Returns the maximum number of digits allowed in the integer portion of a number. The default value is 40, which subclasses can override. When formatting, if the number of digits exceeds this value, the highest- significance digits are truncated until the limit is reached, in accordance with UTS#35. This setting has no effect on parsing.

Returns:int

the maximum number of integer digits

Annotations
@Override
getMinimumIntegerDigitsback to summary
public int getMinimumIntegerDigits()

Overrides com.ibm.icu.text.NumberFormat.getMinimumIntegerDigits.

Doc from com.ibm.icu.text.NumberFormat.getMinimumIntegerDigits.

Returns the minimum number of digits allowed in the integer portion of a number. The default value is 1, which subclasses can override. When formatting, if this value is not reached, numbers are padded on the left with the locale-specific '0' character to ensure at least this number of integer digits. When parsing, this has no effect.

Returns:int

the minimum number of integer digits

hashCodeback to summary
public int hashCode()

Overrides com.ibm.icu.text.NumberFormat.hashCode.

Doc from com.ibm.icu.text.NumberFormat.hashCode.

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns:int

Doc from java.lang.Object.hashCode.

a hash code value for this object.

parseback to summary
public Number parse(String text, ParsePosition parsePosition)

Implements abstract com.ibm.icu.text.NumberFormat.parse.

Doc from com.ibm.icu.text.NumberFormat.parse.

Returns a Long if possible (e.g., within the range [Long.MIN_VALUE, Long.MAX_VALUE] and with no decimals); otherwise, returns another type, such as a BigDecimal, BigInteger, or Double. The return type is not guaranteed other than for the Long case.

If IntegerOnly is set, will stop at a decimal point (or equivalent; e.g., for rational numbers "1 2/3", will stop after the 1).

Does not throw an exception; if no object can be parsed, index is unchanged!

For more detail on parsing, see the "Parsing" header in the class documentation of DecimalFormat.

private void readObject(ObjectInputStream stream) throws IOException, ClassNotFoundException

Hides com.ibm.icu.text.NumberFormat.readObject.

Doc from com.ibm.icu.text.NumberFormat.readObject.

First, read in the default serializable data. Then, if serialVersionOnStream is less than 1, indicating that the stream was written by JDK 1.1, set the int fields such as maximumIntegerDigits to be equal to the byte fields such as maxIntegerDigits, since the int fields were not present in JDK 1.1. Finally, set serialVersionOnStream back to the maximum allowed value so that default serialization will work properly if this object is streamed out again.

setMaximumIntegerDigitsback to summary
public void setMaximumIntegerDigits(int newValue)

Overrides com.ibm.icu.text.NumberFormat.setMaximumIntegerDigits.

Doc from com.ibm.icu.text.NumberFormat.setMaximumIntegerDigits.

Sets the maximum number of digits allowed in the integer portion of a number. This must be >= minimumIntegerDigits. If the new value for maximumIntegerDigits is less than the current value of minimumIntegerDigits, then minimumIntegerDigits will also be set to the new value.

Parameters
newValue:int

the maximum number of integer digits to be shown; if less than zero, then zero is used. Subclasses might enforce an upper limit to this value appropriate to the numeric type being formatted.

Annotations
@Override
setMinimumIntegerDigitsback to summary
public void setMinimumIntegerDigits(int newValue)

Overrides com.ibm.icu.text.NumberFormat.setMinimumIntegerDigits.

Doc from com.ibm.icu.text.NumberFormat.setMinimumIntegerDigits.

Sets the minimum number of digits allowed in the integer portion of a number. This must be <= maximumIntegerDigits. If the new value for minimumIntegerDigits is more than the current value of maximumIntegerDigits, then maximumIntegerDigits will also be set to the new value.

Parameters
newValue:int

the minimum number of integer digits to be shown; if less than zero, then zero is used. Subclasses might enforce an upper limit to this value appropriate to the numeric type being formatted.
