create

public static LocalVariableTableEntry create(DataInput in,
                                             ClassFile classFile)
                                      throws InvalidByteCodeException,
                                             IOException

Factory method for creating LocalVariableTableEntry structures.

Parameters:

in - the DataInput from which to read the LocalVariableTableEntry structure

classFile - the parent class file of the structure to be created

Returns:

the new LocalVariableTableEntry structure

Throws:

InvalidByteCodeException - if the byte code is invalid

IOException - if an exception occurs with the DataInput

getStartPc

public int getStartPc()

Get the start_pc of this local variable association.

Returns:

the start_pc

setStartPc

public void setStartPc(int startPc)

Set the start_pc of this local variable association.

Parameters:

startPc - the start_pc

getLength

public int getLength()

Get the length in bytes of this local variable association.

Returns:

the length

setLength

public void setLength(int length)

Set the length in bytes of this local variable association.

Parameters:

length - the length

getNameIndex

public int getNameIndex()

Get the index of the constant pool entry containing the name of this local variable.

Returns:

the index

setNameIndex

public void setNameIndex(int nameIndex)

Set the index of the constant pool entry containing the name of this local variable.

Parameters:

nameIndex - the index

getDescriptorIndex

public int getDescriptorIndex()

Get the index of the constant pool entry containing the descriptor of this local variable.

Returns:

the index

setDescriptorIndex

public void setDescriptorIndex(int descriptorIndex)

Get the index of the constant pool entry containing the descriptor of this local variable.

Parameters:

descriptorIndex - the index

getIndex

public int getIndex()

Get the index of this local variable.

Returns:

the index

setIndex

public void setIndex(int index)

Set the index of this local variable.

Parameters:

index - 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 AbstractStructure

Parameters:

in - the DataInput from which to read

Throws:

IOException - if an exception occurs with the DataInput

InvalidByteCodeException - if the byte code is invalid

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 AbstractStructure

Parameters:

out - the DataOutput to which to write

Throws:

InvalidByteCodeException - if the structure is internally inconsistent

IOException - if an exception occurs with the DataOutput

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
