PETSC_HASH_MAP#

Instantiate a PETSc hash table map type

Synopsis#

#include <petsc/private/hashmap.h>
PETSC_HASH_MAP(HMapT, KeyType, ValType, HashFunc, EqualFunc, DefaultValue)

Input Parameters#

  • HMapT - The hash table map type name suffix

  • KeyType - The type of keys

  • ValType - The type of values

  • HashFunc - Routine or function-like macro computing hash values from keys

  • EqualFunc - Routine or function-like macro computing whether two values are equal

  • DefaultValue - Default value to use for queries in case of missing keys

Developer Note#

Each time this macro is used to create a new hash map type, the make rule for allmanpages in $PETSC_DIR/makefile should be updated to cause the automatic generation of appropriate manual pages for that type. The manual pages are generated from the templated version of the documentation in include/petsc/private/hashmap.txt.
