int pblMapContainsKey

( PblMap* map, void* key,
  size_t keyLength )

Returns true if this map contains a mapping for the specified key.

Documentation

Returns true if this map contains a mapping for the specified key.

More formally, returns true if and only if this map contains a mapping for a key k such that (key==null ? k==null : memcmp( key, k, keyLength ) == 0. (There can be at most one such mapping.)

For hash maps his method has a time complexity of O(1). For tree maps this method has a time complexity of O(Log N).

Parameters:

map - The map to check
key - Key whose presence in this map is to be tested
keyLength - Length of the key

Returns:

int rc > 0: The map contains a mapping for the specified key.
int rc == 0: The map did not contain a mapping for the key.
