Alle implementierten Schnittstellen:

Serializable, Cloneable, Node

public final class SourceFile
extends Attribute

This class is derived from Attribute and represents a reference to the source file of this class. At most one SourceFile attribute should appear per classfile. The intention of this class is that it is instantiated from the Attribute.readAttribute() method.

SourceFile

public SourceFile(SourceFile c)

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

SourceFile

public SourceFile(int name_index,
 int length,
 int sourcefile_index,
 ConstantPool constant_pool)

Parameter:

name_index - Index in constant pool to CONSTANT_Utf8, which should represent the string "SourceFile".

length - Content length in bytes, the value should be 2.

sourcefile_index - Index in constant pool to CONSTANT_Utf8. This string will be interpreted as the name of the file from which this class was compiled. It will not be interpreted as indicating the name of the directory contqining the file or an absolute path; this information has to be supplied the consumer of this attribute - in many cases, the JVM.

constant_pool - The constant pool that this attribute is associated with.

Methodendetails

accept

public void accept(ClassVisitor 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.

v - Visitor object

dump

public final void dump(DataOutputStream file)
                throws IOException
