GraphicStore createGraphicStore(URI provider, Map<String,Object> params) throws IOException, GraphicStoreException
GraphicStore
connecting to the indicated provider or service.
The returned GraphicStore
may have been previously cached.
Additional hints or configuration information may be provided according
to the metadata indicated by getParametersInfo()
. This information
often includes security information such as username and password.
provider
- Often a URI or JDBC URI locating the service to connect to.params
- Map of hints or configuration information.
GraphicStore
connected to the indicated provider or service.
IOException
- if the GraphicStore
cannot connect to its source.
GraphicStoreException
- if anything else goes wrong while creating the GraphicStore
.GraphicStore createNewGraphicStore(URI provider, Map<String,Object> params) throws IOException, GraphicStoreException
GraphicStore
connecting to the indicated provider or service.
Additional hints or configuration information may be provided according
to the metadata indicated by getParametersInfo()
. This information
often includes security information such as username and password.
provider
- Often a URI or JDBC URI locating the service to connect to.params
- Map of hints or configuration information.
GraphicStore
connected to the newly created provider or service.
IOException
- if the GraphicStore
cannot connect to its source.
GraphicStoreException
- if anything else goes wrong while creating the GraphicStore

to end users.
InternationalString getDescription()
GraphicStore
.
Map<String,Class> getParametersInfo()
Object
array relating to the parameters needed (beyond
the URI) to instantiate a GraphicStore
.
Param
[] based on ISO standards (ISO 19119).boolean canProcess(URI provider)
GraphicStoreFactory
communicate with the indicated provider or service.
This method should not fail, if a connection needs to be made
to parse a GetCapabilities
file or negotiate WMS versions any
IO problems simply indicate the inability to process.
This method may be considered the same as:
canProcess(provider, hints)
where hints was generated by using all the default values specified by the
getParametersInfo()
method.
provider
- Provider or Server of spatial information.boolean canProcess(URI provider, Map<String,Object> params)
GraphicStoreFactory
communicate with the indicated provider or service.
This method differs from canProcess(URI)
in that additional configuration
information may be supplied.
provider
- Provider or Server of spatial information.params
- additional configuration information.
true
if this factory can communicate with the provider.boolean isAvailable()
GraphicStoreFactory
to ensure all its preconditions are met,
such as the presense of required libraries.
true
if available
