Constructor Detail

ModulePackages

public ModulePackages(ModulePackages c)

Initialize from another object. Note that both objects use the same references (shallow copy). Use copy() for a physical copy.

ModulePackages

public ModulePackages(int name_index,
                      int length,
                      int[] package_index_table,
                      ConstantPool constant_pool)

Parameters:

name_index - Index in constant pool

length - Content length in bytes

package_index_table - Table of indices in constant pool

constant_pool - Array of constants

Method Detail

accept

public void accept(Visitor v)

Called by objects that are traversing the nodes of the tree implicitely defined by the contents of a Java class. I.e., the hierarchy of methods, fields, attributes, etc. spawns a tree of objects.

Specified by:

accept in interface Node

Specified by:

accept in class Attribute

Parameters:

v - Visitor object

dump

public void dump(DataOutputStream file)
          throws IOException

Overrides:

dump in class Attribute

Parameters:

file - Output file stream

Throws:

IOException

getPackageIndexTable

public int[] getPackageIndexTable()

Returns:

array of indices into constant pool of package names.

getNumberOfPackages

public int getNumberOfPackages()

Returns:

Length of package table.

getPackageNames

public String[] getPackageNames()

Returns:

string array of package names

setPackageIndexTable

public void setPackageIndexTable(int[] package_index_table)

Parameters:

package_index_table - the list of package indexes Also redefines number_of_packages according to table length.

toString

public String toString()

Overrides:

toString in class Attribute

Returns:

String representation, i.e., a list of packages.

copy

public Attribute copy(ConstantPool _constant_pool)

Specified by:

copy in class Attribute
