Method Detail

create

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

Factory for creating ElementValuePair structures.

Parameters:

in - the DataInput from which to read the ElementValuePair structure

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

Returns:

the new ElementValue structure

Throws:

InvalidByteCodeException - if the byte code is invalid

IOException - if an exception occurs with the DataInput

getElementValue

public ElementValue getElementValue()

Get the element_value of this element value pair.

Returns:

the element_value

setElementValue

public void setElementValue(ElementValue elementValue)

Set the element_value of this element value pair.

Parameters:

elementValue - the element_value

getElementNameIndex

public int getElementNameIndex()

Get the element_name_index of this element value pair.

Returns:

the element_name_index

setElementNameIndex

public void setElementNameIndex(int elementNameIndex)

Set the element_name_index of this element value pair.

Parameters:

elementNameIndex - the element_name_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:

InvalidByteCodeException - if the byte code is invalid

IOException - if an exception occurs with the DataInput

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:

IOException - if an exception occurs with the DataOutput

InvalidByteCodeException - if the structure is internally inconsistent

printAccessFlagsVerbose

protected 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

getLength

protected int getLength()

getEntryName

public String getEntryName()
