Detailed Description

A cheap (efficient) placeholder for a reference to a constant pool record.

A reference can be an open-ended number of (1 or more) integers. In practice, the most integers we see in a reference is two. So this is a slightly more efficient container than an open-ended vector. The field a is the first integer, the field b is the second integer, or zero if there is no second integer. The references are ordered lexicographically. The class also serves to serialize/deserialize references from XML

Member Function Documentation

void ConstantPoolInternal::CheapSorter::apply ( vector< uintb > &  refs ) const

inline

Convert the reference back to a formal array of integers.

Parameters

refs	is the provided container of integers

References CPoolRecord::restoreXml(), and CPoolRecord::saveXml().

Referenced by ConstantPoolInternal::restoreXml().

bool ConstantPoolInternal::CheapSorter::operator< ( const CheapSorter &  op2 ) const

inline

Lexicographic comparison.

Parameters

op2	is the reference to compare with this

Returns

true if this should be ordered before the other reference

References a, and b.

void ConstantPoolInternal::CheapSorter::restoreXml

(

const Element *

el

)

Deserialize the reference from an XML element.

Restore this reference from a <ref> XML tag

Parameters

el	is the XML element

References Element::getAttributeValue().

Referenced by ConstantPoolInternal::restoreXml().

void ConstantPoolInternal::CheapSorter::saveXml

(

ostream &

s

)

const

Serialize the reference to an XML element.

The reference is output as a <ref> tag.

Parameters

s	is the output stream
