Method Detail

substituteConfigParameters

public static String substituteConfigParameters(String namespace,
                                                String string)

Performs variable substitution on the specified string, replacing variables specified like ${name} with the value of the corresponding config parameter obtained from the current context Config object. This version of the method also takes a namespace to qualify the parameter.

Parameters:

namespace - the namespace to use for qualifying the parameter

string - the string on which to perform variable substitution

Returns:

a string with any variables substituted with configuration parameter values

substituteConfigParameters

public static String substituteConfigParameters(String string)

Performs variable substitution on the specified string, replacing variables specified like ${name} with the value of the corresponding config parameter obtained from the current context Config object

Parameters:

string - the string on which to perform variable substitution

Returns:

a string with any variables substituted with configuration parameter values

getKNSParameterValue

public static String getKNSParameterValue(String nameSpace,
                                          String detailType,
                                          String name)

getKNSParameterBooleanValue

public static boolean getKNSParameterBooleanValue(String nameSpace,
                                                  String detailType,
                                                  String name)

getKNSParameterBooleanValue

public static boolean getKNSParameterBooleanValue(String nameSpace,
                                                  String detailType,
                                                  String name,
                                                  boolean defaultValue)

parseGroupNamespaceCode

public static String parseGroupNamespaceCode(String namespaceAndNameCombo)

parseGroupName

public static String parseGroupName(String namespaceAndNameCombo)

isEmpty

public static boolean isEmpty(String value)

isEmpty

public static boolean isEmpty(Collection collection)

isEmpty

public static boolean isEmpty(Object[] array)

equals

public static boolean equals(Object a,
                             Object b)

collectStackTrace

public static String collectStackTrace(Throwable t)

convertTimestamp

public static Calendar convertTimestamp(Timestamp timestamp)

convertCalendar

public static Timestamp convertCalendar(Calendar calendar)

asSet

public static Set asSet(Object[] objects)

asSet

public static Set asSet(Object object)

asList

public static List asList(Object object)

validateDate

public static boolean validateDate(String date,
                                   boolean dateOptional)

checkDateRanges

public static boolean checkDateRanges(String fromDate,
                                      String toDate)

collectionsEquivalent

public static boolean collectionsEquivalent(Collection a,
                                            Collection b)

Performs a "brute force" comparison of collections by testing whether the collections contain each other. This circuments any particular uniqueness or ordering constraints on the collections (for instance, lists that are unordered but contain the same elements, where a hashset would not suffice for comparison purposes because it enforces element uniqueness)

getIpNumber

public static String getIpNumber()

getHostName

public static String getHostName()

getKeyValueCollectionAsMap

public static <T,Z> Map<T,Z> getKeyValueCollectionAsMap(List<? extends org.apache.commons.collections.KeyValue> collection)

Helper method that takes a List of KeyValue and presents it as a Map

Type Parameters:

T - the key type

Z - the value type

Parameters:

collection - collection of KeyValue

Returns:

a Map representing the keys and values in the KeyValue collection

getKeyValueCollectionAsLookupTable

public static <T,Z extends org.apache.commons.collections.KeyValue> Map<T,Z> getKeyValueCollectionAsLookupTable(List<Z> collection)

Helper method that takes a List of KeyValue and presents it as a Map containing KeyValue values

Type Parameters:

T - the key type

Z - the collection/map value type, which must be a KeyValue

Parameters:

collection - collection of KeyValue

Returns:

a Map where keys of the KeyValues in the collection are mapped to their respective KeyValue object
