Class SourceFile

java.lang.Object
org.apache.bcel.classfile.Attribute
org.apache.bcel.classfile.SourceFile
All Implemented Interfaces:
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(int nameIndex, int length, int sourceFileIndex, ConstantPool constantPool)
      Parameters:
      nameIndex - Index in constant pool to CONSTANT_Utf8, which should represent the string "SourceFile".
      length - Content length in bytes, the value should be 2.
      sourceFileIndex - 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.
      constantPool - The constant pool that this attribute is associated with.
    • SourceFile

      Initialize from another object. Note that both objects use the same references (shallow copy). Use clone() for a physical copy.
      Parameters:
      c - Source to copy.

    • accept

      public void accept(Visitor v)

      accept in interface Node
      Specified by:
      accept in class Attribute
      Parameters:
      v - Visitor object
    • copy

      public Attribute copy(ConstantPool constantPool)
      Specified by:
      copy in class Attribute
      Parameters:
      constantPool - constant pool to save.
      Returns:
      deep copy of this attribute
    • dump

      public void dump(DataOutputStream file) throws IOException
      Dump source file attribute to file stream in binary format.

      Parameters:
      file - Output file stream
      Throws:
      IOException - if an I/O error occurs.
    • getSourceFileIndex

      public int getSourceFileIndex()
      Returns:
      Index in constant pool of source file name.

      Returns:
      Source file name.
