Constructor Detail

SourceFile

public SourceFile()
Empty constructor, all attributes have to be defined via `setXXX' methods. Use at your own risk.

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

SourceFile(int name_index, int length, DataInputStream file, ConstantPool constant_pool)
throws java.io.IOException
Construct object from file stream.
Parameters:
name_index - Index in constant pool to CONSTANT_Utf8
length - Content length in bytes
file - Input stream
constant_pool - Array of constants
throw IOException

SourceFile

public SourceFile(int name_index, int length, int sourcefile_index, ConstantPool constant_pool)
Parameters:
name_index - Index in constant pool to CONSTANT_Utf8
length - Content length in bytes
constant_pool - Array of constants
sourcefile_index - Index in constant pool to CONSTANT_Utf8
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.
Parameters:
v - Visitor object

dump

public final void dump(DataOutputStream file)
throws java.io.IOException
Dump source file attribute to file stream in binary format.
Parameters:
file - Output file stream
throw IOException

getConstantPool

public final ConstantPool getConstantPool()
Returns: Constant pool used by this object.
See Also:
ConstantPool

getSourceFileIndex

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

getSourceFileName

public final String getSourceFileName()
Returns: Source file name.

setConstantPool

public final void setConstantPool(ConstantPool constant_pool)
Parameters:
constant_pool - Constant pool to be used for this object.
See Also:
ConstantPool

setSourceFileIndex

public final void setSourceFileIndex(int sourcefile_index)
Parameters:
sourcefile_index.

toString

public final String toString()
Returns: String representation
