Method Summary

Modifier and Type	Method	Description
static boolean	anyModified(VersionedPropertySet diff, Property<?>... props)	Returns true if any of the provided properties are marked as modified in the diff.
static boolean	anyModified(VersionedPropertySet diff, Collection<Property<?>> props)	Returns true if any of the provided properties are marked as modified in the diff.
static BoundValue	bindParameterReference(Object value)
static <T> T	coerce(Property<T> target, Object value)	Attempts to coerce the provided value into the type expected by the provided property.
static Object	coerceUnchecked(Property<?> target, Object value)	This version of coerce does not return a generic type, and also will return a string if the incoming value appears to be a reference.
static Set<Property<?>>	getModifiedProperties(PropertySet original, PropertySet newSet)
static QualifiedValue	getPotentiallyBoundDisplayValue(PropertySet props, Property<?> prop)
static String	getReferenceAsString(Object value)
static boolean	isDefault(Property<?> property, Object value)	Returns true if the value is *essentially* equal to the default value of the property.
static boolean	isReference(Object value)
static void	setPotentialParameterBoundValue(PropertySet props, Property<?> prop, Object value)	Works with potentially non-bindable propertyset, and strings that may not have references.
static <T extends Property<?>> T[]	values(Class<?> classToSearch, Class<? extends T> propType)	Searches the provided class for static Property values and returns them as an array.

Method Details

coerce

public static <T> T coerce(Property<T> target,
 Object value)
                    throws PropertyTypeException

Attempts to coerce the provided value into the type expected by the provided property.

Throws:

PropertyTypeException

coerceUnchecked

public static Object coerceUnchecked(Property<?> target,
 Object value)
                              throws PropertyTypeException

This version of coerce does not return a generic type, and also will return a string if the incoming value appears to be a reference.

Throws:

PropertyTypeException

isDefault

public static boolean isDefault(Property<?> property,
 Object value)

Returns true if the value is *essentially* equal to the default value of the property. "Essentially" means normal equality, but also, Empty List or PropertySet to null and vice versa.

values

public static <T extends Property<?>> T[] values(Class<?> classToSearch,
 Class<? extends T> propType)

Searches the provided class for static Property values and returns them as an array. Does not return null.

Parameters:

classToSearch - the class that has static property definitions

propType - the class type of the properties.

getReferenceAsString

public static String getReferenceAsString(Object value)

isReference

public static boolean isReference(Object value)

bindParameterReference

public static BoundValue bindParameterReference(Object value)

setPotentialParameterBoundValue

public static void setPotentialParameterBoundValue(PropertySet props,
 Property<?> prop,
 Object value)

Works with potentially non-bindable propertyset, and strings that may not have references. If not a reference, will try to coerce into correct value.

getPotentiallyBoundDisplayValue

public static QualifiedValue getPotentiallyBoundDisplayValue(PropertySet props,
 Property<?> prop)

anyModified

public static boolean anyModified(VersionedPropertySet diff,
 Property<?>... props)

Returns true if any of the provided properties are marked as modified in the diff.

anyModified

public static boolean anyModified(VersionedPropertySet diff,
 Collection<Property<?>> props)

Returns true if any of the provided properties are marked as modified in the diff.

getModifiedProperties

public static Set<Property<?>> getModifiedProperties(PropertySet original,
 PropertySet newSet)
