# Java Methods Swept

These are the methods that I have found that reference the system properties table. If you can think of others I have missed, add them (alphabetically) to this list, perform the sweep using Eclipse and add your results.

- `Boolean#getBoolean(String)`
- `Integer#getInteger(String)`
- `Integer#getInteger(String, Integer)`
- `Integer#getInteger(String, int)`
- `Long#getLong(String)`
- `Long#getLong(String, Long)`
- `Long#getLong(String, long)`
- `System#getProperties`
- `System#getProperty(String)`
- `System#getProperty(String, String)`

# Miscellaneous

DistributionConfigImpl constructor prepends `gemfire.` to each valid attribute name, then looks for a System property with that value. If such a property name exists, it overrides any read from a property file or any properties passed into the caller.

`org.apache.geode.internal.cache.Oplog` looks for properties of the form:

- fullRegionName + `_UNIT_BUFF_SIZE`
-- Integer; "Asif: The minimum unit size of the Pool created. The ByteBuffer pools present at different indexes will be multiple of this size. Default unit buffer size is 1024"
- fullRegionName + `_MAX_POOL_SIZE`
-- Integer; "The initial pool size . Default pool size is zero"
- fullRegionName + `_WAIT_TIME`
-- Integer; "Asif: MAX time in milliseconds for which a thread will wait for a buffer to get freed up. If not available in that duration a buffer will be created on the fly. The timeout has no meaning if the max pool size is -1( no upper bound)"
