Class 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.

    • Constructor Detail

      • 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 sourceFileIndex,
                          ConstantPool constantPool)
        Parameters:
        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.
        constantPool - The constant pool that this attribute is associated with.
        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.
