Class AimsBuffer

java.lang.Object
  com.moximedia.aims.AimsBuffer

All Implemented Interfaces:

java.lang.Cloneable, java.io.Serializable

public class AimsBuffer

extends java.lang.Object

implements java.lang.Cloneable, java.io.Serializable

Implementation of ArcIMS buffer. When in SPATIALFILTER, BUFFER defines a new spatial filter polygon; this polygon will be built around the spatial filter's geometry and will be used as new spatial filter. When in SPATIALQUERY, BUFFER defines the polygon that will be built around features extracted by the query. When in SPATIALQUERY, BUFFER may have a TARGETLAYER subtag. In this case, the buffer built around all extracted features will be used as a spatial filter to extract features from the target layer. TODO: Implement targetlayer functionality. In the meantime, similar functionality can be accomplished by using the geometry of the query to build another filter.

Parameters:

project - The project attribute.

getProject

public boolean getProject()

Gets the project attribute setting.

setDistance

public void setDistance(double distance)

Sets the buffer distance

Parameters:

distance - The buffer distance.

getTargetLayerId

Gets the buffer's target layer ID.

Returns:

The target layer for the buffer.

setTargetLayerId

public void setTargetLayerId(java.lang.String targetLayerId)

Sets the buffer's target layer. The target layer is only used by buffers associated with AimsSpatialFilters.

Parameters:

targetLayerId - The target layer for the buffer.

clone

public java.lang.Object clone()

Creates a copy of this object.

Returns:

An object that is a copy of this object. The object must be cast to an AimsBuffer before use.

toAxlString

public java.lang.String toAxlString()

Returns the AXL string to refresh this object, using the default environment coordinate separators. This method is not typically used by the application programmer.

Returns:

The AXL string to refresh this object.

toAxlString

public java.lang.String toAxlString(AimsEnvironment env)

Returns the AXL string to refresh this object, using the coordinate separators in the specified environnment setting. This method is not typically used by the application programmer.

Parameters:

env - The environment object containing coordinate separators.

Returns:

The AXL string to refresh this object.

toAxlString

public java.lang.String toAxlString(java.lang.String requestType,
                                    AimsEnvironment env)

Returns the AXL string to refresh this object, using the coordinate separators in the specified environnment setting. This method is not typically used by the application programmer.

Parameters:

requestType - The parent tag of the buffer, valid values are SPATIALQUERY or null.

env - The environment object containing coordinate separators.

Returns:

The AXL string to refresh this object.
