MBMLEnvironmentFunctions Class Reference

Inherits from	NSObject
Declared in	MBMLEnvironmentFunctions.h

Overview

This class implements MBML functions for accessing Mockingbird runtime environment information.

These functions are exposed to the Mockingbird environment via <Function ... /> declarations in the MBDataEnvironmentModule.xml file.

For more information on MBML functions, see the MBMLFunction class.

`+ mbmlLoadedPaths`

Returns an array of the full pathnames of the MBML files that have been loaded into the current Mockingbird environment.

+ (NSArray *)mbmlLoadedPaths

Return Value

An array containing the paths of the files that have been loaded into the current environment.

Discussion

This Mockingbird function accepts no parameters.

Expression usage

The expression:

^mbmlLoadedPaths()

returns an array containing the full pathnames of the files that have already been loaded.

Declared In

MBMLEnvironmentFunctions.h

`+ mbmlLoadedFiles`

Returns an array of the names (i.e., the lastPathComponents of the file paths) for the files that have been loaded into the current Mockingbird environment.

+ (NSArray *)mbmlLoadedFiles

Return Value

An array containing the names of the files that have been loaded into the current environment.

Discussion

This Mockingbird function accepts no parameters.

Expression usage

The expression:

^mbmlLoadedFiles()

returns an array containing the file names of the files that have already been loaded.

Declared In

MBMLEnvironmentFunctions.h

`+ mbmlPathIsLoaded:`

Determines whether an MBML file with the given pathname has been loaded into the current Mockingbird environment.

+ (NSNumber *)mbmlPathIsLoaded:(NSString *)pathName

Parameters

`pathName`	The full pathname of the file.

Return Value

@YES if the specified file has been loaded into the current environment, @NO otherwise.

Discussion

This Mockingbird function accepts a single parameter: a string expression yielding the full path of the file being tested.

Expression usage

Assume $path evaluates to the full file path of the initial manifest.xml file. The expression:

^mbmlPathIsLoaded($path)

would return @YES if the path represented by the expression $path has already been loaded.

Declared In

MBMLEnvironmentFunctions.h

`+ mbmlFileIsLoaded:`

Determines whether a given MBML file has been loaded into the current Mockingbird environment.

+ (NSNumber *)mbmlFileIsLoaded:(NSString *)fileName

Parameters

`fileName`	The name of the file.

Return Value

@YES if the specified file has been loaded into the current environment, @NO otherwise.

Discussion

This Mockingbird function accepts a single parameter: a string expression yielding the file name (i.e., the lastPathComponent) of the file being tested.

Expression usage

The expression:

^mbmlFileIsLoaded(manifest.xml)

would return a boolean YES if any file named manifest.xml (at any path) has already been loaded.
