configureParameters

public static void configureParameters(java.lang.Object theSource,
                                       java.util.Map<java.lang.String,java.lang.Object> params)
                                throws VIBParameterException

Please use setParameters instead

Throws:

VIBParameterException

configureParameters

public static void configureParameters(java.lang.Object theSource,
                                       java.lang.String parsableString)
                                throws VIBParameterException

Please use setParameters instead

Throws:

VIBParameterException

convertString

public static java.util.Map<java.lang.String,java.lang.Object> convertString(java.lang.String theString,
                                                                             java.lang.ClassLoader classLoader)

This will convert a String in the form (param1 = xxxx, param2 = "stringy", ...) into a hashtable that has key param1 and value xxxx. This is can be used with the configureParameters method above.

getResourceBundle

public static java.util.ResourceBundle getResourceBundle(java.lang.ClassLoader ownersClassLoader,
                                                         java.lang.String resourceFileName)
                                                  throws java.util.MissingResourceException

Returns a resource bundle using the owners class loader. Use this method to ensure that the correct class loader is used. If the incorrect class loader is used, for example, the default class loader the bundle will not load.

Throws:

java.util.MissingResourceException

getResourceBundle

public static java.util.ResourceBundle getResourceBundle(java.lang.Class ownersClass,
                                                         java.lang.String resourceFileName)
                                                  throws java.util.MissingResourceException

Returns a resource bundle using the owners class loader. Use this method to ensure that the correct class loader is used. If the incorrect class loader is used, for example, the default class loader the bundle will not load.

Throws:

java.util.MissingResourceException

getResourceBundle

public static java.util.ResourceBundle getResourceBundle(java.lang.Object owner,
                                                         java.lang.String resourceFileName)
                                                  throws java.util.MissingResourceException

Returns a resource bundle using the owners class loader. Use this method to ensure that the correct class loader is used. If the incorrect class loader is used, for example, the default class loader the bundle will not load.

Throws:

java.util.MissingResourceException

getRuntimeResource

public static java.lang.String getRuntimeResource(java.lang.Object owner,
                                                  java.lang.String key)

logBase10

public static double logBase10(double value)

n2sort

public static void n2sort(ComparableInterface comparer,
                          java.lang.Object[] values)

This is used for easy subclassing if we want to sort.

n2sort

public static void n2sort(ComparableInterface comparer,
                          java.util.Vector values)

This is used for easy subclassing if we want to sort.

setParameters

public static void setParameters(java.lang.Object theSource,
                                 java.util.Map<java.lang.String,java.lang.Object> params)
                          throws VIBParameterException

Sets the parameters to an Object. It also examines each parameter, if a set method exists for this parameter then the set method will be called with the value of the parameter as the argument. NOTE all method names are case insensitive. This will find the first method that has a set method no matter what characters are capitalized. NOTE If the method is not found, it will then check to see if there is a setOption method that takes a Object, String, or TagAgent. TagAgent will only be called if the value is a TagAgent. If it takes a String, then the values.toString() will be sent.

Parameters:

params - the hashtable object keys MUST be strings that represent the value it's trying to set. This string MUST NOT have the 'set' portion of the method. IE: if you want to call the setAngle method, the key will be the string 'angle' (or any case variation because of the case insensitivity).

theSource - This is the object that the set methods will be called on.

params - the data source parameters These exceptions are raised when the server tries to instanciate additional servers that may be part of the parameters of this server.

Throws:

VIBParameterException - An error in the parameters. This wraps all the "normal" exceptions associated with reflection.

setParameters

public static void setParameters(java.lang.Object theSource,
                                 java.lang.String parsableString)
                          throws VIBParameterException

This will take a parsable string, and convert it to a hashtable using the Utils convertString method. Then it will send theSource and the new hashtable to the configureParameters that take these parameters

Throws:

VIBParameterException
