read

public final 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 final 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

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
