Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`boolean`	`containsProperty(java.lang.String key)` Return whether the given property key is available for resolution, i.e.
`java.lang.String`	`getProperty(java.lang.String key)` Return the property value associated with the given key, or `null` if the key cannot be resolved.
`<T> T`	`getProperty(java.lang.String key, java.lang.Class<T> targetValueType)` Return the property value associated with the given key, or `null` if the key cannot be resolved.
`protected <T> T`	`getProperty(java.lang.String key, java.lang.Class<T> targetValueType, boolean resolveNestedPlaceholders)`
`protected java.lang.String`	`getPropertyAsRawString(java.lang.String key)` Retrieve the specified property as a raw String, i.e.
`protected void`	`logKeyFound(java.lang.String key, PropertySource<?> propertySource, java.lang.Object value)` Log the given key as found in the given `PropertySource`, resulting in the given value.

```
public boolean containsProperty(java.lang.String key)
```
    Description copied from interface: PropertyResolver
    
    Return whether the given property key is available for resolution, i.e. if the value for the given key is not null.
    
    Specified by:
    
    containsProperty in interface PropertyResolver
    
    Overrides:
    
    containsProperty in class AbstractPropertyResolver
  - getProperty
```
@Nullable
public java.lang.String getProperty(java.lang.String key)
```
    Description copied from interface: PropertyResolver
    
    Return the property value associated with the given key, or null if the key cannot be resolved.
    
    Specified by:
    
    getProperty in interface PropertyResolver
    
    Overrides:
    
    getProperty in class AbstractPropertyResolver
    
    Parameters:
    
    key - the property name to resolve
    
    See Also:
    
    PropertyResolver.getProperty(String, String), PropertyResolver.getProperty(String, Class), PropertyResolver.getRequiredProperty(String)
  - getProperty
```
@Nullable
public <T> T getProperty(java.lang.String key,
                                   java.lang.Class<T> targetValueType)
```
    Description copied from interface: PropertyResolver
    
    Return the property value associated with the given key, or null if the key cannot be resolved.
    
    Parameters:
    
    key - the property name to resolve
    
    targetValueType - the expected type of the property value
    
    See Also:
    
    PropertyResolver.getRequiredProperty(String, Class)
  - getPropertyAsRawString
```
@Nullable
protected java.lang.String getPropertyAsRawString(java.lang.String key)
```
    Description copied from class: AbstractPropertyResolver
    
    Retrieve the specified property as a raw String, i.e. without resolution of nested placeholders.
    
    Specified by:
    
    getPropertyAsRawString in class AbstractPropertyResolver
    
    Parameters:
    
    key - the property name to resolve
    
    Returns:
    
    the property value or null if none found
  - getProperty
```
@Nullable
protected <T> T getProperty(java.lang.String key,
                                      java.lang.Class<T> targetValueType,
                                      boolean resolveNestedPlaceholders)
```
  - logKeyFound
```
protected void logKeyFound(java.lang.String key,
                           PropertySource<?> propertySource,
                           java.lang.Object value)
```
    Log the given key as found in the given PropertySource, resulting in the given value.
    The default implementation writes a debug log message with key and source. As of 4.3.3, this does not log the value anymore in order to avoid accidental logging of sensitive settings. Subclasses may override this method to change the log level and/or log message, including the property's value if desired.
    
    Parameters:
    
    key - the key found
    
    propertySource - the PropertySource that the key has been found in
    
    value - the corresponding value
    
    Since:
    
    4.3.1
