java.lang.Object

org.aspectj.org.eclipse.jdt.internal.eval.CodeSnippetEnvironment

All Implemented Interfaces:

INameEnvironment, EvaluationConstants

public class CodeSnippetEnvironment
extends Object
implements INameEnvironment, EvaluationConstants

An environment that wraps the client's name environment. This wrapper always considers the wrapped environment then if the name is not found, it search in the code snippet support. This includes the super class org.eclipse.jdt.internal.eval.target.CodeSnippet as well as the global variable classes.

Method Details

findType

public NameEnvironmentAnswer findType(char[][] compoundTypeName)

Description copied from interface: INameEnvironment

Find a type with the given compound name. Answer the binary form of the type if it is known to be consistent. Otherwise, answer the compilation unit which defines the type or null if the type does not exist. Types in the default package are specified as {{typeName}}. It is unknown whether the package containing the type actually exists. NOTE: This method can be used to find a member type using its internal name A$B, but the source file for A is answered if the binary file is inconsistent.

Specified by:

findType in interface INameEnvironment

findType

public NameEnvironmentAnswer findType(char[] typeName,
 char[][] packageName)

Description copied from interface: INameEnvironment

Find a type named <typeName> in the package <packageName>. Answer the binary form of the type if it is known to be consistent. Otherwise, answer the compilation unit which defines the type or null if the type does not exist. The default package is indicated by char[0][]. It is known that the package containing the type exists. NOTE: This method can be used to find a member type using its internal name A$B, but the source file for A is answered if the binary file is inconsistent.

isPackage

public boolean isPackage(char[][] parentPackageName,
 char[] packageName)

Description copied from interface: INameEnvironment

Answer whether packageName is the name of a known subpackage inside the package parentPackageName. A top level package is found relative to null. The default package is always assumed to exist. For example: isPackage({{java}, {awt}}, {event}); isPackage(null, {java});

Specified by:

isPackage in interface INameEnvironment

See Also:

• INameEnvironment.isPackage(char[][], char[])

cleanup

public void cleanup()

Description copied from interface: INameEnvironment

This method cleans the environment. It is responsible for releasing the memory and freeing resources. Passed that point, the name environment is no longer usable. A name environment can have a long life cycle, therefore it is the responsibility of the code which created it to decide when it is a good time to clean it up.
