ResourceLoader (grails-bootstrap 6.2.0 API)

All Known Implementing Classes:

DefaultResourceLoader, FileSystemResourceLoader, StaticResourceLoader
```
public interface ResourceLoader
```
Strategy interface for loading resources (e.. class path or file system resources). An ApplicationContext is required to provide this functionality, plus extended ResourcePatternResolver support.
Bean properties of type Resource and Resource array can be populated from Strings when running in an ApplicationContext, using the particular context's resource loading strategy.

Resource getResource(java.lang.String location)
```
    Return a Resource handle for the specified resource. The handle should always be a reusable resource descriptor, allowing for multiple Resource#getInputStream() calls.
    
    Must support fully qualified URLs, e.g. "file:C:/test.dat".
    Must support classpath pseudo-URLs, e.g. "classpath:test.dat".
    Should support relative file paths, e.g. "WEB-INF/test.dat". (This will be implementation-specific, typically provided by an ApplicationContext implementation.)
    
    Note that a Resource handle does not imply an existing resource; you need to invoke Resource#exists to check for existence.
    Parameters:
    
    location - the resource location
    
    Returns:
    
    a corresponding Resource handle

    CLASSPATH_URL_PREFIX
  - getClassLoader
```
java.lang.ClassLoader getClassLoader()
```
    Expose the ClassLoader used by this ResourceLoader.
    Clients which need to access the ClassLoader directly can do so in a uniform manner with the ResourceLoader, rather than relying on the thread context ClassLoader.
    
    Returns:
    
    the ClassLoader (never null)
