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

apply()

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 a, and b.

Referenced by ConstantPoolInternal::restoreXml().

operator<()

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.

restoreXml()

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().

saveXml()

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

References a, a_v_u(), and b.
