Method Summary

java.lang.String[]	getAlias(java.lang.String propetry) returns the alieas names of the datastore fields assigned to a property
java.lang.String	getCRS() returns the name of the coordinated reference system the geo spatial data are stored.
java.lang.String[]	getDatastoreField(java.lang.String property) returns the names of the datastore fields a property of the feature type will be mapped to
int	getDatastoreFieldType(java.lang.String datastoreField) returns the type of a named datastore fields The types are encoded like defined at java.sql.types
java.lang.String	getInternalCRS() returns the name of the coordinated reference system as it is used within the data source.
java.util.HashMap	getMappings() returns all mappings with property names as keys
MasterTable	getMasterTable() returns the description of the datastores master table
java.lang.String	getName() returns the name of the feature type
OutputFormat[]	getOutputFormat() returns an array of objects that describes the output formatting for the feature type. at least one
OutputFormat	getOutputFormat(java.lang.String name) returns a named output format. if no output format with the submitted name is known null will be returned
TableDescription[]	getPath(java.lang.String property) returns the list (in correct order) of tables that are used to reach the submitted property
java.lang.String	getProperty(java.lang.String datastoreField) returns the names of the property a datastore field will be mapped to
java.lang.String	getPropertyFromAlias(java.lang.String alias) returns the names of the property a datastore field (alias) will be mapped to
int	getPropertyType(java.lang.String property) returns the type of the property a datastore field will be mapped to
java.lang.String	getReferencedBy(java.lang.String name) returns the name of the table where the submitted table (name) is referenced by.
RelatedTable[]	getRelatedTables() returns a description of all tables that are related direct or indirect to the master table. if no related tables are defined the method returns a zero length array
TableDescription	getTableByName(java.lang.String name) returns a description object for the table identified by the submitted name.
boolean	isPropertyKnown(java.lang.String property) Checks if a Property (XPath-expression or mapping) is known to the datastore.

Method Detail

getName

public java.lang.String getName()

returns the name of the feature type

getOutputFormat

public OutputFormat[] getOutputFormat()

returns an array of objects that describes the output formatting for the feature type. at least one

getOutputFormat

public OutputFormat getOutputFormat(java.lang.String name)

returns a named output format. if no output format with the submitted name is known null will be returned

getMappings

public java.util.HashMap getMappings()

returns all mappings with property names as keys

getDatastoreField

public java.lang.String[] getDatastoreField(java.lang.String property)

returns the names of the datastore fields a property of the feature type will be mapped to

getAlias

public java.lang.String[] getAlias(java.lang.String propetry)

returns the alieas names of the datastore fields assigned to a property

getPropertyFromAlias

public java.lang.String getPropertyFromAlias(java.lang.String alias)

returns the names of the property a datastore field (alias) will be mapped to

getProperty

public java.lang.String getProperty(java.lang.String datastoreField)

returns the names of the property a datastore field will be mapped to

getDatastoreFieldType

public int getDatastoreFieldType(java.lang.String datastoreField)

returns the type of a named datastore fields The types are encoded like defined at java.sql.types

isPropertyKnown

public boolean isPropertyKnown(java.lang.String property)

Checks if a Property (XPath-expression or mapping) is known to the datastore. XPath expressions (e.g. "/TABLE/FIELD") are only valid, if no mappings are defined at all. Properties may be used if they are explicitly defined in the datastore configuration.

Parameters:

property - Property to be looked up

Returns:

true, if it is known, else false

getPropertyType

public int getPropertyType(java.lang.String property)

returns the type of the property a datastore field will be mapped to

getMasterTable

public MasterTable getMasterTable()

returns the description of the datastores master table

getRelatedTables

public RelatedTable[] getRelatedTables()

returns a description of all tables that are related direct or indirect to the master table. if no related tables are defined the method returns a zero length array

getReferencedBy

public java.lang.String getReferencedBy(java.lang.String name)

returns the name of the table where the submitted table (name) is referenced by. If the name of the master table is submitted, null will be returned because it isn't referenced by a related table.

getTableByName

public TableDescription getTableByName(java.lang.String name)

returns a description object for the table identified by the submitted name. if no table with the submitted can be found null will be returned.

getCRS

public java.lang.String getCRS()

returns the name of the coordinated reference system the geo spatial data are stored.

getInternalCRS

public java.lang.String getInternalCRS()

returns the name of the coordinated reference system as it is used within the data source. This code may differs from the EPSG code stored in element

getPath

public TableDescription[] getPath(java.lang.String property)

returns the list (in correct order) of tables that are used to reach the submitted property
