All Known Implementing Classes:

LineNumberTableEntry

public interface LineNumberTableEntry
extends java.lang.Cloneable, BytesCountable

Class representing a Line Number Table instance's entry. Each entry in the line_number_table array indicates that the line number in the original source file changes at a given point in the code array

Method Detail

setStartPc

void setStartPc(int startPc)

The value of the start_pc item must indicate the index into the code array at which the code for a new line in the original source file begins. The value of start_pc must be less than the value of the code_length item of the Code attribute of which this LineNumberTable is an attribute

Parameters:

startPc - A valid value as defined above

getStartPc

int getStartPc()

The value of the start_pc item must indicate the index into the code array at which the code for a new line in the original source file begins. The value of start_pc must be less than the value of the code_length item of the Code attribute of which this LineNumberTable is an attribute

Returns:

int A valid value as defined above

setLineNumber

void setLineNumber(int lineNumber)

The value of the line_number item must give the corresponding line number in the original source file

Parameters:

lineNumber - The line number value

getLineNumber

int getLineNumber()

The value of the line_number item must give the corresponding line number in the original source file

Returns:

int The line number value

setAttributeContainer

void setAttributeContainer(LineNumberTableAttribute attr)

Set the LineNumberTableAttribute containing the current LineNumberTableEntry

Parameters:

attr - The container

getAttributeContainer

LineNumberTableAttribute getAttributeContainer()

Get the LineNumberTableAttribute containing the current LineNumberTableEntry

Returns:

LineNumberTableAttribute The container

fromStream

void fromStream(java.io.DataInputStream dis)
                throws java.io.IOException

Reads the line number table entry from the given input stream.

Parameters:

dis - The input stream the line number table entry has to be read from

Throws:

java.io.IOException - Something went wrong with the given stream

toStream

void toStream(java.io.DataOutputStream dos)
              throws java.io.IOException

Writes the line number table entry to the given output stream.

Parameters:

dos - The output stream the line number table entry has to be written to

Throws:

java.io.IOException - Something went wrong with the given stream

validate

void validate()
              throws MissingAttributeContainerException,
                     LineNumberTableEntryValidationException

Performs the validation of the current LineNumberTableEntry.

Throws:

MissingAttributeContainerException

LineNumberTableEntryValidationException

clone

java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Throws:

java.lang.CloneNotSupportedException
