MapPropertyResolver

public MapPropertyResolver(java.util.Map<java.lang.String,java.lang.Object> map,
                           ConversionService conversionService)

map - The map to resolves the properties from

conversionService - The conversion service

Method Detail

containsProperty

public boolean containsProperty(java.lang.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(java.lang.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

getProperty

public <T> java.util.Optional<T> getProperty(java.lang.String name,
                                             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

getPropertyEntries

@NonNull
public java.util.Collection<java.lang.String> getPropertyEntries(@NonNull
                                                                          java.lang.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.
