Field Detail

SET

public static final PojoPropertyAccessorOneArgMode SET

The mode for a regular setter of a property.

ADD

public static final PojoPropertyAccessorOneArgMode ADD

The mode for an accessor used to add an item to a property with a container (array or Collection) type. The accessor will add the item given as argument to the end of the container (if ordered). If the container is an array a copy with a size increased by 1 has to be created. Therefore a virtual add-accessor can only be generated for array-type getters if also an according setter is present.

Collection.add(Object)

REMOVE

public static final PojoPropertyAccessorOneArgMode REMOVE

The mode for an accessor used to remove an item from a property with an container (array or Collection) type. The accessor will remove the first occurrence of the item given as argument from the container. It will return true on success and false if the item was NOT found in the container. If the container is an array a copy with a size decreased by 1 has to be created. Therefore a virtual remove-accessor can only be generated for array-type getters if also an according setter is present.

Collection.remove(Object)

GET_MAPPED

public static final PojoPropertyAccessorOneArgMode GET_MAPPED

The mode for a getter of a mapped property.
For example an invoke with argument key for a property named "colors" might cause a pojo.getColors().get(key) or pojo.getColors(key) or even pojo.getColor(key).
