Method Detail

decodeURI

public static String decodeURI(String encodedURI)

Decodes an encoded URI to a URI string.

decodeURIComponent

public static String decodeURIComponent(String encodedURIComponent)

Decodes an encoded URI component to a URI component string.

encodeURI

public static String encodeURI(String uri)

Encodes a URI string by escaping all characters not allowed in URIs.

encodeURIComponent

public static String encodeURIComponent(String uriComponent)

Encodes a URI component string by escaping all characters not allowed in URIs.

isFinite

public static boolean isFinite(double value)

Indicates if value is a finite number.

isNaN

public static boolean isNaN(double value)

Indicates if value is NaN.

parseFloat

public static double parseFloat(String value)

Produces a double value by interpreting the contents of value as a decimal literal.

parseFloat

public static double parseFloat(String value,
                                int radix)

Produces a double value by interpreting the contents of value as a decimal literal.

parseInt

public static double parseInt(String value)

Produces a integral value by interpreting the contents of value as a integer literal. The value returned by this method will be an integral value or NaN, so the return value is a double.

 Example use:
 // Will yield zero if s is not a valid integer.
 int value = (int)parseInt(s);
 
 // To check if the value is valid.
 double value = parseInt(s);
 if (isNaN(value))
   //Invalid value.
 

parseInt

public static double parseInt(String value,
                              int radix)

Produces a integral value by interpreting the contents of value as a integer literal. The value returned by this method will be an integral value or NaN, so the return value is a double.

 Example use:
 // Will yield zero if s is not a valid integer.
 int value = (int)parseInt(s);
 
 // To check if the value is valid.
 double value = parseInt(s);
 if (isNaN(value))
   //Invalid value.
