## Member Function Documentation

bool log4cplus::helpers::Properties::exists | ( | const log4cplus::tstring & | key | ) | const`[inline]`

| Tests to see if `key` can be found in this map. Definition at line 47 of file property.h.

log4cplus::tstring log4cplus::helpers::Properties::getProperty | ( | const log4cplus::tstring & | key,
|  | const log4cplus::tstring & | defaultVal
| ) | const

| Searches for the property with the specified key in this property list. If the key is not found in this property list, the default property list, and its defaults, recursively, are then checked. The method returns the default value argument if the property is not found.

log4cplus::tstring log4cplus::helpers::Properties::getProperty | ( | const log4cplus::tstring & | key | ) | const

| Searches for the property with the specified key in this property list. If the key is not found in this property list, the default property list, and its defaults, recursively, are then checked. The method returns `null` if the property is not found.

Properties log4cplus::helpers::Properties::getPropertySubset | ( | const log4cplus::tstring & | prefix | ) | const

| Returns a subset of the "properties" whose keys start with "prefix". The returned "properties" have "prefix" trimmed from their keys.

void log4cplus::helpers::Properties::init | ( | log4cplus::tistream & | input | ) | `[protected]`

std::vector<log4cplus::tstring> log4cplus::helpers::Properties::propertyNames | ( |  | ) | const

| Returns all the keys in this property list.

bool log4cplus::helpers::Properties::removeProperty | ( | const log4cplus::tstring & | key | ) |

| Removed the property index by `key` from this map.

void log4cplus::helpers::Properties::setProperty | ( | const log4cplus::tstring & | key,
|  | const log4cplus::tstring & | value
| ) |

| Inserts `value` into this map indexed by `key`.

size_t log4cplus::helpers::Properties::size | ( |  | ) | const`[inline]`

| Returns the number of entries in this map. Definition at line 55 of file property.h.
