Constructor Detail

Default

public Default(TypeDescription typeDescription,
               byte[] binaryRepresentation,
               LoadedTypeInitializer loadedTypeInitializer,
               List<? extends DynamicType> auxiliaryTypes)

Creates a new dynamic type.

Parameters:

typeDescription - A description of this dynamic type.

binaryRepresentation - A byte array containing the binary representation of this dynamic type.

loadedTypeInitializer - The loaded type initializer of this dynamic type.

auxiliaryTypes - The auxiliary type required for this dynamic type.

Method Detail

getTypeDescription

public TypeDescription getTypeDescription()

Description copied from interface: DynamicType

Returns a description of this dynamic type.

Specified by:

getTypeDescription in interface DynamicType

Returns:

A description of this dynamic type.

getLoadedTypeInitializers

public Map<TypeDescription,LoadedTypeInitializer> getLoadedTypeInitializers()

Description copied from interface: DynamicType

Returns a map of all loaded type initializers for the main type and all auxiliary types, if any.

Specified by:

getLoadedTypeInitializers in interface DynamicType

Returns:

A mapping of all types' descriptions to their loaded type initializers.

hasAliveLoadedTypeInitializers

public boolean hasAliveLoadedTypeInitializers()

Description copied from interface: DynamicType

Checks if a dynamic type requires some form of explicit type initialization, either for itself or for one of its auxiliary types, if any. This is the case when this dynamic type was defined to delegate method calls to a specific instance which is stored in a field of the created type. If this class serialized, it could not be used without its loaded type initializers since the field value represents a specific runtime context.

Specified by:

hasAliveLoadedTypeInitializers in interface DynamicType

Returns:

true if this type requires explicit type initialization.

getBytes

public byte[] getBytes()

Description copied from interface: DynamicType

Returns a byte array representing this dynamic type. This byte array might be reused by this dynamic type and must therefore not be altered.

Specified by:

getBytes in interface DynamicType

Returns:

A byte array of the type's binary representation.

getRawAuxiliaryTypes

public Map<TypeDescription,byte[]> getRawAuxiliaryTypes()

Description copied from interface: DynamicType

Returns a map of all auxiliary types that are required for making use of the main type.

Specified by:

getRawAuxiliaryTypes in interface DynamicType

Returns:

A map of all auxiliary types by their descriptions to their binary representation.

saveIn

public Map<TypeDescription,File> saveIn(File folder)
                                 throws IOException

Description copied from interface: DynamicType

Saves a dynamic type in a given folder using the Java class file format while respecting the naming conventions for saving compiled Java classes. All auxiliary types, if any, are saved in the same directory. The resulting folder structure will resemble the structure that is required for Java run times, i.e. each folder representing a segment of the package name. If the specified folder does not yet exist, it is created during the call of this method.

Specified by:

saveIn in interface DynamicType

Parameters:

folder - The base target folder for storing this dynamic type and its auxiliary types, if any.

Returns:

A map of type descriptions pointing to files with their stored binary representations within folder.

Throws:

IOException - Thrown if the underlying file operations cause an IOException.

inject

public File inject(File sourceJar,
                   File targetJar)
            throws IOException

Description copied from interface: DynamicType

Injects the types of this dynamic type into a given jar file. Any pre-existent type with the same name is overridden during injection. The target file's folder must exist prior to calling this method. The file itself is overwritten or created depending on its prior existence.

Specified by:

inject in interface DynamicType

Parameters:

sourceJar - The original jar file.

targetJar - The source jar file with the injected contents.

Returns:

The target jar file.

Throws:

IOException - If an IO exception occurs while injecting from the source into the target.

inject

public File inject(File jar)
            throws IOException

Description copied from interface: DynamicType

Injects the types of this dynamic type into a given jar file. Any pre-existent type with the same name is overridden during injection.

Specified by:

inject in interface DynamicType

Parameters:

jar - The jar file to replace with an injected version.

Returns:

The jar file.

Throws:

IOException - If an IO exception occurs while injecting into the jar.

toJar

public File toJar(File file,
                  Manifest manifest)
           throws IOException

Description copied from interface: DynamicType

Saves the contents of this dynamic type inside a jar file. The folder of the given file must exist prior to calling this method.

Specified by:

toJar in interface DynamicType

Parameters:

file - The target file to which the jar is written to.

manifest - The manifest of the created jar.

Returns:

The given file.

Throws:

IOException - If an IO exception occurs while writing the file.

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
