Detailed Description

An implementation of the ConstantPool interface storing records internally in RAM.

The CPoolRecord objects are held directly in a map container. This class can be used as a stand-alone ConstantPool that holds all its records in RAM. Or, it can act as a local CPoolRecord cache for some other implementation.

Member Function Documentation

getRecord()

const CPoolRecord * ConstantPoolInternal::getRecord ( const vector< uintb > &  refs ) const

virtual

Retrieve a constant pool record (CPoolRecord) given a reference to it.

Parameters

refs	is the reference (made up of 1 or more identifying integers)

Returns

the matching CPoolRecord or NULL if none matches the reference

Implements ConstantPool.

restoreXml()

void ConstantPoolInternal::restoreXml ( const Element *  el, TypeFactory &  typegrp  )

virtual

Restore constant pool records from an XML stream.

(If supported) The container is populated with CPooLRecords initialized from a <constantpool> XML tag.

Parameters

el	is the XML element
typegrp	is the TypeFactory used to resolve data-type references in the XML

Implements ConstantPool.

saveXml()

void ConstantPoolInternal::saveXml ( ostream &  s ) const

virtual

Save all records in this container to an XML stream.

(If supported) An <constantpool> element is written containing <cpoolrec> child elements for each CPoolRecord in the container.

Parameters

s	is the output stream

Implements ConstantPool.
