Parameters:

startPc - the start_pc

endPc - the end_pc

handlerPc - the handler_pc

catchType - the constant pool index for the catch type of this exception table entry

Method Detail

create

public static ExceptionTableEntry create(java.io.DataInput in,
                         ClassFile classFile)
                                  throws InvalidByteCodeException,
                                         java.io.IOException

Factory method for creating ExceptionTableEntry structures.

Parameters:

in - the DataInput from which to read the ExceptionTableEntry structure

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

Returns:

the new ExceptionTableEntry structure

Throws:

InvalidByteCodeException - if the byte code is invalid

java.io.IOException - if an exception occurs with the DataInput

getStartPc

public int getStartPc()

Get the start_pc of this exception table entry.

Returns:

the start_pc

setStartPc

public void setStartPc(int startPc)

Set the start_pc of this exception table entry.

Parameters:

startPc - the start_pc

getEndPc

public int getEndPc()

Get the end_pc of this exception table entry.

Returns:

the end_pc

setEndPc

public void setEndPc(int endPc)

Set the end_pc of this exception table entry.

Parameters:

endPc - the end_pc

getHandlerPc

public int getHandlerPc()

Get the handler_pc of this exception table entry.

Returns:

the handler_pc

setHandlerPc

public void setHandlerPc(int handlerPc)

Set the handler_pc of this exception table entry.

Parameters:

handlerPc - the handler_pc

getCatchType

public int getCatchType()

Get the constant pool index for the catch type of this exception table entry.

Returns:

the index

setCatchType

public void setCatchType(int catchType)

Set the constant pool index for the catch type of this exception table entry.

Parameters:

catchType - the index

read

public void read(java.io.DataInput in)
          throws InvalidByteCodeException,
                 java.io.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:

InvalidByteCodeException - if the byte code is invalid

java.io.IOException - if an exception occurs with the DataInput

write

public void write(java.io.DataOutput out)
           throws InvalidByteCodeException,
                  java.io.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

java.io.IOException - if an exception occurs with the DataOutput

debug

protected void debug(java.lang.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

printAccessFlagsVerbose

protected java.lang.String printAccessFlagsVerbose(int accessFlags)

Description copied from class: AbstractStructure

Utility method for derived structures. Print an access flag as a space separated list of verbose java access modifiers.

Specified by:

printAccessFlagsVerbose in class AbstractStructure

Parameters:

accessFlags - the unsigned short value to print as a hex string

Returns:

the hex string
