All Implemented Interfaces:

Serializable, Comparable<Property>

public class BindingProperty
extends Property

Represents a single named deferred binding or configuration property that can answer with its value. The BindingProperty maintains two sets of values, the "defined" set and the "allowed" set. The allowed set must always be a subset of the defined set.

Method Detail

addCollapsedValues

public void addCollapsedValues(String... values)

Add an equivalence set of property values.

addDefinedValue

public void addDefinedValue(Condition condition,
                            String newValue)

addFallbackValue

public void addFallbackValue(String value,
                             String fallbackValue)

Adds fall back value to given property name.

Parameters:

value - the property value.

fallbackValue - the fall back value for given property value.

getAllowedValues

public String[] getAllowedValues(Condition condition)

Returns the set of allowed values in sorted order when a certain condition is satisfied.

getCollapsedValues

public List<SortedSet<String>> getCollapsedValues()

getConditionalValues

public Map<Condition,SortedSet<String>> getConditionalValues()

getConstrainedValue

public String getConstrainedValue()

If the BindingProperty has exactly one value across all conditions and permutations, return that value otherwise return null.

getDefinedValues

public String[] getDefinedValues()

Returns the set of defined values in sorted order.

getFallback

public String getFallback()

Returns the fallback value for this property, or the empty string if none.

Returns:

the fallback value

getFallbackValuesMap

public Map<String,? extends List<? extends Set<String>>> getFallbackValuesMap()

Returns the map of values to fall back values. the list of fall back values is in decreasing order of preference.

Returns:

map of property value to fall back values.

getFirstLegalValue

public String getFirstLegalValue()

Returns the first legal value for this property that can be found.

getProvider

public PropertyProvider getProvider()

getProviderGenerator

public Class<? extends PropertyProviderGenerator> getProviderGenerator()

Returns:

the provider generator class, or null if none.

getRequiredProperties

public Set<String> getRequiredProperties()

getRootCondition

public ConditionAll getRootCondition()

isAllowedValue

public boolean isAllowedValue(String value)

Returns true if the supplied value is legal under some condition.

isDefinedValue

public boolean isDefinedValue(String value)

Returns true if the value was previously provided to addDefinedValue(Condition,String).

isDerived

public boolean isDerived()

Returns true if the value of this BindingProperty is always derived from other BindingProperties. That is, for each Condition in the BindingProperty, there is exactly one allowed value.

setAllowedValues

public void setAllowedValues(Condition condition,
                             String... values)

Set the currently allowed values. The values provided must be a subset of the currently-defined values.

Throws:

IllegalArgumentException - if any of the provided values were not provided to addDefinedValue(Condition,String).

setFallback

public void setFallback(String token)

setProvider

public void setProvider(PropertyProvider provider)

setProviderGenerator

public void setProviderGenerator(Class<? extends PropertyProviderGenerator> generator)

Set a provider generator for this property.

Parameters:

generator -
