datatypeDetector - is the DatatypeDetector instance.

validator - is the Validator instance.

mathUtil - is the MathUtilLimited instance.

Method Detail

getMathUtil

protected MathUtilLimited getMathUtil()

Returns:

the mathUtil

copy

public VALUE copy(VALUE value)

This method creates a copy (e.g. via copy-constructor or clone) of the given value. If the given value is immutable (like String, Long, etc.) it is legal to return the same given instance.

Specified by:

copy in interface UiDataBindingAdapter<VALUE>

Parameters:

value - is the value to copy.

Returns:

the copy of the value.

createNewValue

public VALUE createNewValue()

Specified by:

createNewValue in interface UiDataBindingAdapter<VALUE>

Returns:

a new instance of <VALUE>.

copy

private <V> V copy(V value,
                   PojoDescriptor<V> pojoDescriptor)

Type Parameters:

V - the generic type of the value (for recursive invocation).

Parameters:

value - is the value to copy.

pojoDescriptor - is the PojoDescriptor for value.

Returns:

the copy of value.

See Also:

copy(Object)

getPropertyValidator

public <T> ValueValidator<T> getPropertyValidator(TypedProperty<T> property,
                                                  Class<T> propertyType)

This method gets or creates the ValueValidator for the specified property.

Specified by:

getPropertyValidator in interface UiDataBindingAdapter<VALUE>

Type Parameters:

T - is the generic property type.

Parameters:

property - is the TypedProperty.

propertyType - is the Class reflecting the property type.

Returns:

the ValueValidator for the given property.

getRangeConstraints

public <T> Range<?> getRangeConstraints(TypedProperty<T> property,
                                        Class<T> propertyType)

This method determines the allowed Range of the value for the specified property in the Pojo associated with this adapter. It will consider JSR 303 annotations such as Min, Max, DecimalMin, and DecimalMax.

Specified by:

getRangeConstraints in interface UiDataBindingAdapter<VALUE>

Type Parameters:

T - is the generic type of the property.

Parameters:

property - is the TypedProperty.

propertyType - is the Class reflecting the property type.

Returns:

the Range or null if unbound.

getPropertyType

public <T> Class<T> getPropertyType(TypedProperty<T> property)

This method gets the property type of the given TypedProperty. This method might work even if TypedProperty.getPropertyType() returns null.

Specified by:

getPropertyType in interface UiDataBindingAdapter<VALUE>

Type Parameters:

T - is the generic property type.

Parameters:

property - is the TypedProperty.

Returns:

the property type of the given property.

getPropertyValue

public <T> T getPropertyValue(VALUE pojo,
                              TypedProperty<T> property)

This method gets the value of the specified property.

Specified by:

getPropertyValue in interface UiDataBindingAdapter<VALUE>

Type Parameters:

T - is the generic property type.

Parameters:

pojo - is the Pojo owning the property.

property - is the TypedProperty.

Returns:

the value of the specified property.

See Also:

UiDataBindingAdapter.getPropertyValue(Object, String)

getPropertyValue

public Object getPropertyValue(VALUE pojo,
                               String property)

This method gets the value of the specified property.
E.g. getPropertyValue(pojo, "foo") is supposed to return pojo.getFoo().

Specified by:

getPropertyValue in interface UiDataBindingAdapter<VALUE>

Parameters:

pojo - is the Pojo owning the property.

property - is the name of the requested property.

Returns:

the value of the specified property.

setPropertyValue

public <T> void setPropertyValue(VALUE pojo,
                                 TypedProperty<T> property,
                                 T propertyValue)

This method sets the value of the specified property.

Specified by:

setPropertyValue in interface UiDataBindingAdapter<VALUE>

Type Parameters:

T - is the generic property type.

Parameters:

pojo - is the Pojo owning the property.

property - is the TypedProperty.

propertyValue - is the property value to set.

See Also:

UiDataBindingAdapter.setPropertyValue(Object, String, Object)

setPropertyValue

public void setPropertyValue(VALUE pojo,
                             String property,
                             Object propertyValue)

This method sets the value of the specified property.
E.g. setPropertyValue(pojo, "foo", value) is supposed to do pojo.setFoo(value).

Specified by:

setPropertyValue in interface UiDataBindingAdapter<VALUE>

Parameters:

pojo - is the Pojo owning the property.

property - is the name of the property to set.

propertyValue - is the property value to set.
