Method Details

splitUpQueryColVals

public static DOFWUtils.SplitUpColVals splitUpQueryColVals(Object... colVals)

Split the object array into the conditions array and the order-by array. The split is done by searching the String ICCEEConstants.ORDERBY as delimiter.

quc

public static String quc(String contextName,
 String columnName)

Query update column. - This function is used when building the actual SQL statement: column names by default are written without modification into the SQL statement - some DB servers require some surrounding quotes. Example: if using case-sensitive column names with Oracle, then column names have to be surrounded by \".

qut

public static String qut(String contextName,
 String tableName)

Query update table. - Transfers the table name while writing the SQL statement. The table name might be embedded into some \"-characters (dependent on DB server). And schema information might be prepended.

replaceVariables

public static DOFWUtils.ReplaceResult replaceVariables(String contextName,
 Class clazz,
 String s)

findPropertiesInColumns

public static List<DOFWProperty> findPropertiesInColumns(Class clazz,
 String[] colSelections)

replacePropertyNames

public static String replacePropertyNames(String contextName,
 Class clazz,
 String s)

parseICCEEConstant

public static String parseICCEEConstant(String s)

Converts the text of a ICCEEConstants-constant into a correpsonding constant representation. Background: all operations with ICCEEConstants are done by directling accessing the pointer - e.g. all checks for equality are done using "==" and not using ".equals(..)".

checkIfPropertyHasCenturyColumn

public static boolean checkIfPropertyHasCenturyColumn(DOFWProperty property)

transferSortStringIntoDOFWQueryObjects

public static Object[] transferSortStringIntoDOFWQueryObjects(String query)

transferSortStringIntoDOFWQueryObjects

public static Object[] transferSortStringIntoDOFWQueryObjects(String[] query)

transferQueryStringIntoDOFWQueryObjects

public static Object[] transferQueryStringIntoDOFWQueryObjects(String className,
 String query)

Parameters:

query - Example: "att1 IS 4711 and att2 IS Harry and att3 IS 'Harry Hirsch'

transferQueryStringIntoDOFWQueryObjects

public static Object[] transferQueryStringIntoDOFWQueryObjects(String className,
 String[] query)

Same as transferQueryStringIntoDOFWQueryObjects(String, String) but now query is passed as array of string tokens.

transferKeyPathIntoQuery

public static Object[] transferKeyPathIntoQuery(String keyPath,
 Class beanClass)

checkIfKeyOfObjectsIsSame

public static boolean checkIfKeyOfObjectsIsSame(Object bean1,
 Object bean2)

resolveKeyPathForBean

public static String resolveKeyPathForBean(Object bean)

resolveKeyPathForBean

public static String resolveKeyPathForBean(Object bean,
 String delimiter)

mergeOrderBys

public static Object[] mergeOrderBys(Object[] sort1,
 Object[] sort2)

Two sequences of order by objects are merged. The first sequence is the dominating one, the objects of sort2 are added - if not already present in the first sequence.

Parameters:

sort1 - First sequence

sort2 - Second sequence
