public FeatureSchema()

Method Detail

clone

public Object clone()

Overrides:

clone in class Object

getAttributeIndex

public int getAttributeIndex(String attributeName)

Returns the zero-based index of the attribute with the given name (case-sensitive)

Throws:

IllegalArgumentException - if attributeName is unrecognized

hasAttribute

public boolean hasAttribute(String attributeName)

Returns whether this FeatureSchema has an attribute with this name

Parameters:

attributeName - the name to look up

Returns:

whether this FeatureSchema has an attribute with this name

getGeometryIndex

public int getGeometryIndex()

Returns the attribute index of the Geometry, or -1 if there is no Geometry attribute

getAttributeName

public String getAttributeName(int attributeIndex)

Returns the (case-sensitive) name of the attribute at the given zero-based index.

getAttributeType

public AttributeType getAttributeType(int attributeIndex)

Returns whether the attribute at the given zero-based index is a string, integer, double, etc.

getAttributeType

public AttributeType getAttributeType(String attributeName)

Returns whether the attribute with the given name (case-sensitive) is a string, integer, double, etc.

getAttributeCount

public int getAttributeCount()

Returns the total number of spatial and non-spatial attributes in this FeatureSchema. There are 0 or 1 spatial attributes and 0 or more non-spatial attributes.

addAttribute

public void addAttribute(String attributeName,
                         AttributeType attributeType)

Adds an attribute with the given case-sensitive name.

Throws:

AssertionFailedException - if a second Geometry is being added

equals

public boolean equals(Object other)

Returns whether the two FeatureSchemas have the same attribute names with the same types and in the same order.

Overrides:

equals in class Object

equals

public boolean equals(Object other,
                      boolean orderMatters)

Returns whether the two FeatureSchemas have the same attribute names with the same types and (optionally) in the same order.

setCoordinateSystem

public FeatureSchema setCoordinateSystem(CoordinateSystem coordinateSystem)

Sets the CoordinateSystem associated with this FeatureSchema, but does not perform any reprojection.

Returns:

this FeatureSchema

getCoordinateSystem

public CoordinateSystem getCoordinateSystem()
