  • Field Details

    • UNDEFINED

      static final int UNDEFINED
      usable for int definitions that are not bitfields
      See Also:

    • UNSET

      static final int UNSET
      usable for all int definitions like bitfiels type and style
      See Also:

  • Method Details

    • getFormat

      Format getFormat()
      format-constraint for the attributes value

    • getType

      Class<T> getType()
      value type

    • checkStatus

      IStatus checkStatus(String name, T value)
      checks, if the given value is valid - should not throw an exception

    • check

      void check(String name, T value)
      checks, if the given value is valid - throws an exception

    • getDefault

      T getDefault()
      default value for this attribute

    • getMinimum

      Comparable<T> getMinimum()
      returns the minimum value or null

    • getMaximum

      Comparable<T> getMaximum()
      returns the maximum value or null

    • getAllowedValues

      Collection<T> getAllowedValues()
      returns the allowed values or null

    • getLength

      int getLength()
      maximum length - useful on strings

    • getScale

      int getScale()
      scale - useful for numbers of type BigDecimal

    • getPrecision

      int getPrecision()
      precision - useful for numbers of type BigDecimal

    • isNullable

      boolean isNullable()
      should return true, if attribute-value may be null

    • setBasicDef

      <C extends IConstraint<T>> C setBasicDef(int length, boolean nullable, Format format, T defaultValue)
      define some basic attribute definitions

    • setNumberDef

      <C extends IConstraint<T>> C setNumberDef(int scale, int precision)
      define number definitions - if the attribute is a number

    • setRange

      <C extends IConstraint<T>> C setRange(Comparable<T> min, Comparable<T> max)
      defines a min/max range constraint. use ValueCompare to compare on changing values

    • setRange

      <C extends IConstraint<T>> C setRange(Collection<T> allowedValues)
      defines all allowed values - if you call setRange(Comparable, Comparable), you shouldn't call this method

    • setFormat

      <C extends IConstraint<T>> C setFormat(Format format)
      define constraining text format. use RegularExpressionFormat to define a regexp pattern

    • setType

      <C extends IConstraint<T>> C setType(Class<T> type)
      define type

    • setLength

      <C extends IConstraint<T>> C setLength(int length)
      define maximum length

    • setScale

      <C extends IConstraint<T>> C setScale(int scale)
      define scale

    • setPrecision

      <C extends IConstraint<T>> C setPrecision(int precision)
      define precision

    • setNullable

      <C extends IConstraint<T>> C setNullable(boolean nullable)
      define nullable

    • setDefault

      <C extends IConstraint<T>> C setDefault(T defaultValue)

    • fromString

      static Object fromString(Class<?> type, String def)
