  • Constructor Details

    • MutablePropertyValues

      public MutablePropertyValues()
      Creates a new empty MutablePropertyValues object.

      Property values can be added with the add method.

      See Also:

    • MutablePropertyValues

      public MutablePropertyValues(@Nullable PropertyValues original)
      Deep copy constructor. Guarantees PropertyValue references are independent, although it can't deep copy objects currently referenced by individual PropertyValue objects.
      Parameters:
      original - the PropertyValues to copy
      See Also:

    • MutablePropertyValues

      public MutablePropertyValues(@Nullable Map<?,?> original)
      Construct a new MutablePropertyValues object from a Map.
      Parameters:
      original - a Map with property values keyed by property name Strings
      See Also:

    • MutablePropertyValues

      public MutablePropertyValues(@Nullable List<PropertyValue> propertyValueList)
      Construct a new MutablePropertyValues object using the given List of PropertyValue objects as-is.

      This is a constructor for advanced usage scenarios. It is not intended for typical programmatic use.

      Parameters:
      propertyValueList - a List of PropertyValue objects

  • Method Details

    • getPropertyValueList

      public List<PropertyValue> getPropertyValueList()
      Return the underlying List of PropertyValue objects in its raw form. The returned List can be modified directly, although this is not recommended.

      This is an accessor for optimized access to all PropertyValue objects. It is not intended for typical programmatic use.

    • size

      public int size()
      Return the number of PropertyValue entries in the list.

    • addPropertyValues

      public MutablePropertyValues addPropertyValues(@Nullable PropertyValues other)
      Copy all given PropertyValues into this object. Guarantees PropertyValue references are independent, although it can't deep copy objects currently referenced by individual PropertyValue objects.
      Parameters:
      other - the PropertyValues to copy
      Returns:
      this in order to allow for adding multiple property values in a chain

    • addPropertyValues

      public MutablePropertyValues addPropertyValues(@Nullable Map<?,?> other)
      Add all property values from the given Map.
      Parameters:
      other - a Map with property values keyed by property name, which must be a String
      Returns:
      this in order to allow for adding multiple property values in a chain

    • addPropertyValue

      public MutablePropertyValues addPropertyValue(PropertyValue pv)
      Add a PropertyValue object, replacing any existing one for the corresponding property or getting merged with it (if applicable).
      Parameters:
      pv - the PropertyValue object to add
      Returns:
      this in order to allow for adding multiple property values in a chain

    • addPropertyValue

      public void addPropertyValue(String propertyName, Object propertyValue)
      Overloaded version of addPropertyValue that takes a property name and a property value.

      Note: As of Spring 3.0, we recommend using the more concise and chaining-capable variant add(java.lang.String, java.lang.Object).

      Parameters:
      propertyName - name of the property
      propertyValue - value of the property
      See Also:

    • add

      public MutablePropertyValues add(String propertyName, @Nullable Object propertyValue)
      Add a PropertyValue object, replacing any existing one for the corresponding property or getting merged with it (if applicable).
      Parameters:
      propertyName - name of the property
      propertyValue - value of the property
      Returns:
      this in order to allow for adding multiple property values in a chain

    • setPropertyValueAt

      public void setPropertyValueAt(PropertyValue pv, int i)
      Modify a PropertyValue object held in this object. Indexed from 0.

    • removePropertyValue

      public void removePropertyValue(PropertyValue pv)
      Remove the given PropertyValue, if contained.
      Parameters:
      pv - the PropertyValue to remove

    • removePropertyValue

      public void removePropertyValue(String propertyName)
      Overloaded version of removePropertyValue that takes a property name.
      Parameters:
      propertyName - name of the property
