Here is the call graph for this function:

getProperty() [1/2]

static final String org.jau.sys.PropertyAccess.getProperty ( final String propertyKey, final boolean jnlpAlias ) throws SecurityException, NullPointerException, IllegalArgumentException

static

Query the property with the name propertyKey.

If jnlpAlias is true and the plain propertyKey could not be resolved, an attempt to resolve the JNLP aliased trusted property is made.
Example: For the propertyName OneTwo, the jnlp alias name is jnlp.OneTwo, which is considered trusted.

Parameters

propertyKey	the property name to query.
jnlpAlias	true if a fallback attempt to query the JNLP aliased trusted property shall be made, otherwise false.

Returns

the property value if exists, or null

Exceptions

NullPointerException	if the property name is null
IllegalArgumentException	if the property name is of length 0
SecurityException	if access is not allowed to the given propertyKey
