Constructor Details

PropertySourcePropertyResolver

public PropertySourcePropertyResolver(ConversionService conversionService,
 boolean logEnabled)

Creates a new, initially empty, PropertySourcePropertyResolver for the given ConversionService.

Parameters:

conversionService - The ConversionService

logEnabled - flag to enable or disable logger

PropertySourcePropertyResolver

public PropertySourcePropertyResolver(ConversionService conversionService)

Creates a new, initially empty, PropertySourcePropertyResolver for the given ConversionService.

Parameters:

conversionService - The ConversionService

PropertySourcePropertyResolver

public PropertySourcePropertyResolver()

Creates a new, initially empty, PropertySourcePropertyResolver.

PropertySourcePropertyResolver

public PropertySourcePropertyResolver(PropertySource... propertySources)

Creates a new PropertySourcePropertyResolver for the given PropertySource instances.

Parameters:

propertySources - The PropertySource instances

Method Details

addPropertySource

public PropertySourcePropertyResolver addPropertySource(@Nullable
 @Nullable PropertySource propertySource)

Add a PropertySource to this resolver.

Parameters:

propertySource - The PropertySource to add

Returns:

This PropertySourcePropertyResolver

addPropertySource

public PropertySourcePropertyResolver addPropertySource(String name,
 @Nullable
 @Nullable Map<String,? super Object> values)

Add a property source for the given map.

Parameters:

name - The name of the property source

values - The values

Returns:

This environment

containsProperty

public boolean containsProperty(@Nullable
 @Nullable String name)

Description copied from interface: PropertyResolver

Whether the given property is contained within this resolver.

Note that this method will return false for nested properties. In other words given a key of foo.bar this method will return false for: resolver.containsProperty("foo")

To check for nested properties using PropertyResolver.containsProperties(String) instead.

Specified by:

containsProperty in interface PropertyResolver

Parameters:

name - The name of the property

Returns:

True if it is

containsProperties

public boolean containsProperties(@Nullable
 @Nullable String name)

Description copied from interface: PropertyResolver

Whether the given property or any nested properties exist for the key given key within this resolver.

Specified by:

containsProperties in interface PropertyResolver

Parameters:

name - The name of the property

Returns:

True if it is

getPropertyEntries

@NonNull
public @NonNull Collection<String> getPropertyEntries(@NonNull
 @NonNull String name)

Description copied from interface: PropertyResolver

Returns a collection of properties entries under the given key. For example given the following keys:

 datasource.default.url=localhost
 datasource.another.url=someother
 

Calling getPropertyEntries(String) with a value of datasource will result in a collection containing default and other.

Specified by:

getPropertyEntries in interface PropertyResolver

Parameters:

name - The name to resolve

Returns:

The property entries.

getPropertyPathMatches

public Set<List<String>> getPropertyPathMatches(String pathPattern)

Description copied from interface: PropertyResolver

Will return for a given pattern such as foo.*.bar.* and array of arrays containing the variable names that match the pattern.

Specified by:

getPropertyPathMatches in interface PropertyResolver

Parameters:

pathPattern - The path pattern

Returns:

An array of arrays.

getProperties

@NonNull
public @NonNull Map<String,Object> getProperties(String name,
 StringConvention keyFormat)

Description copied from interface: PropertyResolver

Return all the properties under the given key. By default Micronaut stores keys in keb-case, such that normalized lookups are more efficient. You can obtain the raw key values by passing in StringConvention.RAW.

Specified by:

getProperties in interface PropertyResolver

Parameters:

name - The name

keyFormat - The key format to use for the keys. Default is kebab-case.

Returns:

The properties

getProperty

public <T> Optional<T> getProperty(@NonNull
 @NonNull String name,
 @NonNull
 @NonNull ArgumentConversionContext<T> conversionContext)

Description copied from interface: PropertyResolver

Resolve the given property for the given name, type and generic type arguments.

Implementers can choose to implement more intelligent type conversion by analyzing the typeArgument.

Specified by:

getProperty in interface PropertyResolver

Type Parameters:

T - The concrete type

Parameters:

name - The name

conversionContext - The conversion context

Returns:

An optional containing the property value if it exists

getAllProperties

public Map<String,Object> getAllProperties(StringConvention keyConvention,
 MapFormat.MapTransformation transformation)

Returns a combined Map of all properties in the catalog.

Parameters:

keyConvention - The map key convention

transformation - The map format

Returns:

Map of all properties

resolveSubProperties

The subproperties

resolveSubMap

protected Map<String,Object> resolveSubMap(String name,
 Map<String,Object> entries,
 ArgumentConversionContext<?> conversionContext)

Parameters:

name - The property name

entries - The entries

conversionContext - The conversion context

Returns:

The submap

resolveSubMap

@NonNull
protected @NonNull Map<String,Object> resolveSubMap(String name,

 ArgumentConversionContext<?> conversionContext,
 @Nullable
 @Nullable StringConvention keyConvention,
 MapFormat.MapTransformation transformation)

Resolves a submap for the given name and parameters.

Parameters:
