Constructor Detail

ClassPathUtils

public ClassPathUtils()

ClassPathUtils instances should NOT be constructed in standard programming. Instead, the class should be used as ClassPathUtils.toFullyQualifiedName(MyClass.class, "MyClass.properties");.

This constructor is public to permit tools that require a JavaBean instance to operate.

Method Detail

toFullyQualifiedName

public static String toFullyQualifiedName(Class<?> context,
                                          String resourceName)

Returns the fully qualified name for the resource with name resourceName relative to the given context.

Note that this method does not check whether the resource actually exists. It only constructs the name. Null inputs are not allowed.

 ClassPathUtils.toFullyQualifiedName(StringUtils.class, "StringUtils.properties") = "org.apache.commons.lang3.StringUtils.properties"
 

Parameters:

context - The context for constructing the name.

resourceName - the resource name to construct the fully qualified name for.

Returns:

the fully qualified name of the resource with name resourceName.

Throws:

NullPointerException - if either context or resourceName is null.

toFullyQualifiedName

public static String toFullyQualifiedName(Package context,
                                          String resourceName)

Returns the fully qualified name for the resource with name resourceName relative to the given context.

Note that this method does not check whether the resource actually exists. It only constructs the name. Null inputs are not allowed.

 ClassPathUtils.toFullyQualifiedName(StringUtils.class.getPackage(), "StringUtils.properties") = "org.apache.commons.lang3.StringUtils.properties"
 

Parameters:

context - The context for constructing the name.

resourceName - the resource name to construct the fully qualified name for.

Returns:

the fully qualified name of the resource with name resourceName.

Throws:

NullPointerException - if either context or resourceName is null.

toFullyQualifiedPath

public static String toFullyQualifiedPath(Class<?> context,
                                          String resourceName)

Returns the fully qualified path for the resource with name resourceName relative to the given context.

Note that this method does not check whether the resource actually exists. It only constructs the path. Null inputs are not allowed.
