Method Detail

setIntrospector

public void setIntrospector(ClassIntrospector introspector)

Sets introspector implementation.

setTypeConverterManager

public void setTypeConverterManager(TypeConverterManager typeConverterManager)

Sets type converter manager implementation.

convertType

protected java.lang.Object convertType(java.lang.Object value,
                                       java.lang.Class type)

Converts object to destination type. Invoked before the value is set into destination. Throws TypeConversionException if conversion fails.

convertToCollection

protected java.lang.Object convertToCollection(java.lang.Object value,
                                               java.lang.Class destinationType,
                                               java.lang.Class componentType)

Converter to collection.

invokeSetter

protected java.lang.Object invokeSetter(Setter setter,
                                        BeanProperty bp,
                                        java.lang.Object value)

Invokes setter, but first converts type to match the setter type.

arrayForcedGet

protected java.lang.Object arrayForcedGet(BeanProperty bp,
                                          java.lang.Object array,
                                          int index)

Returns the element of an array forced. If value is null, it will be instantiated. If not the last part of indexed bean property, array will be expanded to the index if necessary.

arrayForcedSet

protected void arrayForcedSet(BeanProperty bp,
                              java.lang.Object array,
                              int index,
                              java.lang.Object value)

Sets the array element forced. If index is greater then arrays length, array will be expanded to the index. If speed is critical, it is better to allocate an array with proper size before using this method.

ensureArraySize

protected java.lang.Object ensureArraySize(BeanProperty bp,
                                           java.lang.Object array,
                                           java.lang.Class componentType,
                                           int index)

ensureListSize

protected void ensureListSize(java.util.List list,
                              int size)

indexOfDot

protected int indexOfDot(java.lang.String name)

Finds the very first next dot. Ignores dots between index brackets. Returns -1 when dot is not found.

extractIndex

protected java.lang.String extractIndex(BeanProperty bp)

Extract index string from non-nested property name. If index is found, it is stripped from bean property name. If no index is found, it returns null.

parseInt

protected int parseInt(java.lang.String indexString,
                       BeanProperty bp)

createBeanProperty

protected java.lang.Object createBeanProperty(BeanProperty bp)

Creates new instance for current property name through its setter. It uses default constructor!

extractGenericComponentType

protected java.lang.Class extractGenericComponentType(Getter getter)

Extracts generic component type of a property. Returns Object.class when property does not have component.

convertIndexToMapKey

protected java.lang.Object convertIndexToMapKey(Getter getter,
                                                java.lang.Object index)

Converts Map index to key type. If conversion fails, original value will be returned.

extractType

protected java.lang.Class extractType(BeanProperty bp)

Extracts type of current property.
