public interface XQueryImplementation
extends Implementation

Class representing the XQuery implementation type

Method Summary

java.lang.String	getLocation() Location of the XQuery implementation file
java.lang.String	getLocationURL()
java.lang.String	getXqExpression() The XQuery expression that is loaded from the XQuery implementation file
java.util.Map<java.lang.reflect.Method,java.lang.String>	getXqExpressionExtensionsMap() The XQuery expression should be extended for with additional script, which provides the external variables needed to invoke a function.

Method Detail

getLocation

java.lang.String getLocation()

Location of the XQuery implementation file

Returns:

setLocation

void setLocation(java.lang.String location)

getLocationURL

java.lang.String getLocationURL()

setLocationURL

void setLocationURL(java.lang.String location)

getXqExpression

java.lang.String getXqExpression()

The XQuery expression that is loaded from the XQuery implementation file

Returns:

setXqExpression

void setXqExpression(java.lang.String expression)

getXqExpressionExtensionsMap

java.util.Map<java.lang.reflect.Method,java.lang.String> getXqExpressionExtensionsMap()

The XQuery expression should be extended for with additional script, which provides the external variables needed to invoke a function. In this way for each function that is defined in the original XQuery expression additional expression is defined, which can invoke this function, using external variables as input. These expression extensions are stored in this map. It provides for each method of a service interface that is implemented by this component type corresponding expression extension

Returns:

getCompiledExpressionsCache

java.util.Map<java.lang.String,XQueryExpression> getCompiledExpressionsCache()

This map is a kind of cache for function invocations. If a given XQuery function of this implementation has been invoked already its compiled expression can be reused. In this manner the performance can be increased

Returns:
