| org.geotools.data.oracle.sdo.CoordinateAccess
| CoordinateAccess | | public interface CoordinateAccess extends CoordinateSequence(Code) | | Allows manipulation of a Geometry's CoordianteSequece.
The number of ordinates in each Coordiante is getDimension() + getNumAttributes()
The examples given in this interface are based on a 2-dimensional
coordinate system, x and y,
with two attributes: z and t.
In this case z is the third dimension, but is not used for rendering and
the coordinate
remains 2-dimensional.

| Method Summary | |
| Object | getAttribute(int coordinate, int attribute)
getAttribute purpose. | | int | getDimension()
Retrieve the number of spatial dimensions of Coordiantes. | | int | getNumAttributes()
Retrieve number of measures associated with a Coordiantes
This is the number of non spatially significant ordinates. | | double | getOrdinate(int coordinate, int ordinate)
| | void | setAt(int coordinate, double[] ordinates, Object[] attributes)
Allows modification of a single coordinate (including attribute values).
Normal Use: where D is getDimensions() and N is getNumAttributes():
dimensions: [ ordX, ordY, ..., ordD ]
attributes: [ atr1, atr2, ...., atrN ]
When dealing with attributes that are all double values the ordinates
array may be used to set both ordinates and attribute values.
Optimized Use: where D is getDimensions() and N is getNumAttributes():
dimensions: [ ordX, ordY, ..., ordD, atr1, atr2, ...
| | void | setAttribute(int coordinate, int attribute, Object value)
setAttribute purpose. | | void | setAttributeArray(int attribute, Object attributeArray)
setAttributeArray purpose. | | void | setCoordinateArrays(double[][] ordinateArrays, Object[] attributeArrays)
Completely replace sequence with the provided information. | | void | setOrdinate(int coordinate, int ordinate, double value)
Set a single ordinate. | | void | setOrdinateArray(int ordinate, double[] ordinateArray)
Supplies an array of ordiantes. | | Object[] | toAttributeArray(int attribute)
toAttributeArray purpose. | | Object[] | toAttributeArrays()
Retrieve Attribute information (an array of attributes for each
coordiante). | | double[] | toOrdinateArray(int ordinate)
Retrive ordinates as an array.
Example: (x,y) getDimension()==2
This is defined for the number of dimensions. | | double[][] | toOrdinateArrays()
Retrieve ordinate information (an array of ordinates for each
coordinate). |
| getAttribute | | Object getAttribute(int coordinate, int attribute)(Code) | | getAttribute purpose.
attribute is between 0 and getNumAttributes()
Parameters:
coordinate -
Parameters:
attribute - is between 0 and getNumAttributes() |
| getDimension | | int getDimension()(Code) | | Retrieve the number of spatial dimensions of Coordiantes.
This is the number of spatially significant ordiantes (usually 2 or 3)
Number of spatially signficant ordinates |
| getNumAttributes | | int getNumAttributes()(Code) | | Retrieve number of measures associated with a Coordiantes
This is the number of non spatially significant ordinates.
Number of measures, or 0 if measures not used |
| getOrdinate | | double getOrdinate(int coordinate, int ordinate)(Code) | | Retrive a single ordinate
Parameters:
coordinate - Coordinate to retrive from
Parameters:
ordinate - Ordinate to retrive from coordiante Specified ordinate |
| setAt | | void setAt(int coordinate, double[] ordinates, Object[] attributes)(Code) | | Allows modification of a single coordinate (including attribute values).
Normal Use: where D is getDimensions() and N is getNumAttributes():
dimensions: [ ordX, ordY, ..., ordD ]
attributes: [ atr1, atr2, ...., atrN ]
When dealing with attributes that are all double values the ordinates
array may be used to set both ordinates and attribute values.
Optimized Use: where D is getDimensions() and N is getNumAttributes():
dimensions: [ ordX, ordY, ..., ordD, atr1, atr2, ... attrN ]
attributes: null
Parameters:
coordinate - index of coordiante to be modified
Parameters:
ordinates - array ordinate values (may be extended with attributevalues)
Parameters:
attributes - array of attribute values, or null is ordinates hasbeen extended |
| setAttribute | | void setAttribute(int coordinate, int attribute, Object value)(Code) | | setAttribute purpose.
attribute is between 0 and getNumAttributes()
Parameters:
coordinate - the coordinate to be modified
Parameters:
attribute - between 0 and getNumAttributes()
Parameters:
value - |
| setAttributeArray | | void setAttributeArray(int attribute, Object attributeArray)(Code) | | setAttributeArray purpose.
Description ...
Parameters:
attribute - between 0 and getNumAttributes()
Parameters:
attributeArray - May be an object or primative array |
| setCoordinateArrays | | void setCoordinateArrays(double[][] ordinateArrays, Object[] attributeArrays)(Code) | | Completely replace sequence with the provided information.
Example: (x,y,m,g) getDimension()==2, getNumAttributes()==2
dimensions:[ [ x1, x2,...,xN], [ y1, y2,...,yN] ]
attributes:[ [ m1, m2,...,mN], [ g1, g2,..., gN] ]
Parameters:
ordinateArrays - dimensions column major ordinate arrays (these are spatially significant)
Parameters:
attributeArrays - Indiviual attribute arrays may be primative orobject arrays |
| setOrdinate | | void setOrdinate(int coordinate, int ordinate, double value)(Code) | | Set a single ordinate.
Parameters:
coordinate - Corrdinate to modify
Parameters:
ordinate - Ordinate to modify in coordinate
Parameters:
value - new value |
| setOrdinateArray | | void setOrdinateArray(int ordinate, double[] ordinateArray)(Code) | | Supplies an array of ordiantes.
The ordinateArray should be the same length as the CoordinateSequence.
ordinate should be between 0 and getDimension().
If the attributes are doubles as well, then ordinate can be as great as
getDimension() + getNumAttributes().
|
| toAttributeArray | | Object[] toAttributeArray(int attribute)(Code) | | toAttributeArray purpose.
Description ...
Parameters:
attribute - Between 0 and getNumAttrributes() an array of attributes |
| toAttributeArrays | | Object[] toAttributeArrays()(Code) | | Retrieve Attribute information (an array of attributes for each
coordiante).
Example: (x,y,m,g) getDimension()==2, getAttributes()==2
[ [ m1, m2,...,mN], [ g1, g2,..., gN] ]
Attribute Arrays, may be object or primative arrays |
| toOrdinateArray | | double[] toOrdinateArray(int ordinate)(Code) | | Retrive ordinates as an array.
Example: (x,y) getDimension()==2
This is defined for the number of dimensions. If the other attributes
happen to be a double, they can still be accessed by using an ordinate
value geater than getDimension().
-
ordinate 0: x ordinate
-
ordinate 1: y ordinate
-
ordinate 2: m attribute
-
ordinate 3: g attribute
Parameters:
ordinate - Ordinate to retrieve. ordinate is less than
getDimension()+getMeasures() if the measures are doubles aswell. Otherwise
ordinate is less than getDimensions(). ordinate array |

coordinate).
Example: (x,y,m,g) getDimension()==2, getNumAttributes()==2
[ [ x1, x2,...,xN], [ y1, y2,...,yN] ]
column major ordinate arrays (these are spatially significant) |
