Class DefaultOperators

java.lang.Object
com.isomorphic.criteria.DefaultOperators
public class DefaultOperators extends Object
Helper class for accessing operators that needs for working with Criteria. Also it contains set of methods for values check.

  • Method Details

    • isEqualToConfiguredValue

      public static boolean isEqualToConfiguredValue(Object value, String operand) throws Exception
      Returns true if argument "value" (presumed to come from a DataSource) is equal to the value represented by argument "operand" (a String, presumed to come from a .ds.xml file). Otherwise returns false.

      This is meant to be a wrapper class around isEqual(), handling the most common cases of type conversion and data conditioning.

      Throws:
      Exception

    • isEqual

      public static boolean isEqual(Object value, Object operand) throws Exception
      Compare two objects in a style suitable for Advanced Criteria operators. This should follow the same equality semantics as implemented in DataSource.js. It should also generally follow equality semantics for SQL.
      Throws:
      Exception

    • rangeCheckToConfiguredValues

      public static boolean rangeCheckToConfiguredValues(Object value, String lower, String upper, boolean inclusive, boolean caseInsensitive) throws Exception
      Evaluates: "lower (< <=) value (< <=) upper", where value is an object (presumably from a record), and lower and upper are Strings, presumably parsed from a .ds.xml file, which are converted to the type of value prior to comparison.
      Throws:
      Exception

    • rangeCheck

      public static boolean rangeCheck(Object value, Object lower, Object upper, boolean inclusive, boolean caseInsensitive) throws Exception
      Evaluates: "lower (< <=) value (< <=) upper", where lower, value, and upper are presumed to be objects of (nearly) the same type.
      Throws:
      Exception

    • isMatchingPattern

      public static boolean isMatchingPattern(String value, String matchesPattern, boolean ignoreCase) throws Exception
      Checks to see if the value matches the pattern described allowing for multi wildcard character '*' and single wildcard characters '%' and '?'
      Throws:
      Exception

    • isStartsWithPattern

      public static boolean isStartsWithPattern(String value, String matchesPattern, boolean ignoreCase) throws Exception
      Checks to see if the value starts with the pattern described allowing for multi wildcard character '*' and single wildcard characters '%' and '?'
      Throws:
      Exception

    • isEndsWithPattern

      public static boolean isEndsWithPattern(String value, String matchesPattern, boolean ignoreCase) throws Exception

      Throws:
      Exception

    • getDefaultOperatorMap

      public static Map<String,Operator> getDefaultOperatorMap()
      Retrieving the Map containing all default operators.
