Constructor Detail

LineNumberTableAttribute

public LineNumberTableAttribute()

Method Detail

getLineNumberTable

public LineNumberTableEntry[] getLineNumberTable()

Get the list of line number associations of the parent Code structure as an array of LineNumberTableEntry structures.

Returns:

the array

setLineNumberTable

public void setLineNumberTable(LineNumberTableEntry[] lineNumberTable)

Set the list of line number associations of the parent Code structure as an array of LineNumberTableEntry structures.

Parameters:

lineNumberTable - the index

read

public void read(DataInput in)
          throws InvalidByteCodeException,
                 IOException

Description copied from class: AbstractStructure

Read this structure from the given DataInput.

Excpects DataInput to be in JVM class file format and just before a structure of this kind. No look ahead parsing since the class file format is deterministic.

Overrides:

read in class AttributeInfo

Throws:

InvalidByteCodeException

IOException

write

public void write(DataOutput out)
           throws InvalidByteCodeException,
                  IOException

Description copied from class: AbstractStructure

Write this structure to the given DataOutput.

The written bytes are in JVM class file format.

Overrides:

write in class AttributeInfo

Throws:

InvalidByteCodeException

IOException

getAttributeLength

public int getAttributeLength()

Description copied from class: AttributeInfo

Get the length of this attribute as a number of bytes.

Overrides:

getAttributeLength in class AttributeInfo

Returns:

the length

debug

protected void debug(String message)

Description copied from class: AbstractStructure

Utility method for derived structures. Dump a specific debug message.

Overrides:

debug in class AbstractStructure

Parameters:

message - the debug message
